gif2bgi

- -A program to display images saved as GIF files on IBM PC display devices using -the BGI (Borland) driver interface.

- -The program operates as follows:

- -

    -
  1. -Reads the GIF file header and determines the image size.

    - -

  2. -Dynamically allocates enough memory to hold all the image internally. -One byte per pixel is always allocated, so a little bit more than -width*height (of screen, not image) bytes are required.

    - -

  3. -Reads all the image in. Interlaced images are read in correctly, although -they are displayed sequentially.

    - -

  4. -Display first image using the defaults as set by the command line option.

    - -

  5. -Goes to interactive mode. For a full description of the interactive mode -see below.

    -

- -

Usage:

- -
-gif2bgi [-q] [-d BGI dir] [-u driver] [-z zoom] [-b] [-h] gif-file
-
- -If no GIF is given, gif2bgi will try to read a GIF file from stdin.

- -

Memory required:

- -Screen. - -

Options:

-
-
[-q] -
Quiet mode. Default off on MSDOS, on under UNIX. Controls printout - of running scan lines. Use -q- to invert.

- -

[-d BGI Directory] -
Where we should look for default drivers (as supplied by Borland). - For example '-d c:/tc/bgi'.

- -

[-u driver] -
Specifies a user-defined BGI driver. If for example - you have a BGI driver for your special vga called MYVGA.BGI and you want - to run it in mode 2, then type '-u c:/tc/bgi/myvga.2'. Note the absolute - path to the driver must be specified. Also note that we use '/' and not - '\' so they won't be treated as options.

- -

[-z zoom] -
Sets zoom factor of the view. Zoom factor should be - power of 2 up to 256. Default is 1 (no zoom).

- -

[-h] -
Print one line of command-line help, similar to Usage above.

-

- -

Interactive mode:

- -Once the image is displayed, the gif2bgi program goes into interactive mode -which recognizes the following commands:

- -

-
C - get Color and position -
In this submenu, a cursor appears and the location and color of the - pixel underneath it are printed. The 4 arrows may be used (shifted for - faster movement) to move the cursor. Any other key will abort this submode.

- -

D - zoom Down -
Zoom down by factor of 2 unless current zoom factor is 1.

- -

R - Redraw -
Redraw the image.

- -

S - print Status -
Print status of image and program.

- -

U - zoom Up -
Zoom up by factor of 2 unless current zoom factor is 256.

- -

arrow keys -
The 4 arrow keys can be used to pan in the desired direction, if the image - overflows in that direction. If the image fits into the screen, arrow - keys are ignored. The panning steps are 1/2 screen if not on image end.

- -

SPC - abort -
Space bar may be used to abort current image drawing.

- -

ESC - abort -
Escape may be used to abort current image drawing. -
- - -

Notes:

- -This program is useless in a Unix environment and is not normally -built there.

- -No color quantization is used in this program; thus, if a GIF image has more -colors than the BGI driver support, this program will abort.

- -This driver is optimized for drivers with one byte per pixel (256 colors) -and will run MUCH faster on such drivers.

- -

Bugs:

- -For some reason I could not figure out, on my ATI wonder card, int 10h call -10h (AH = AL = 10h) to set the color registers sometimes result with wrong -colors. Direct access of the card registers gives correct results.

gif2epsn

- -A program to dump images saved as GIF files on Epson type printers.

- -

Usage:

- -
-gif2epsn [-q] [-d dither] [-t bw] [-m map] [-i] [-n] [-p printer] [-h] gif-file
-
- -If no gif-file is given, Gif2Epsn will try to read a GIF file from stdin.

- - -

Memory required:

- -Screen. - -

Options:

- -
-
[-q] -
Quiet mode. Default off on MSDOS, on under UNIX. Controls printout - of running scan lines. Use -q- to invert.

- -

[-d dither] -
Sets size of dithering matrix, where DitherSize can be - 2,3 or 4 only (for 2x2, 3x3 and 4x4 dithering matrices). Default is 2. - Note image will be displayed in this mode only if the mapping - option (see -m) selected this mode.

- -

[-t bw] -
Sets threshold level for B&W mapping in percent. - This threshold level is used in the different mappings as selected via -m. - Default is 19%.

- -

[-m map] -
Select method to map colors to B&W. Mapping can be: - -
-
0
- Every none background color is considered foreground (white color but - is drawn as black by printer, unless -i is specified).

- -

1
- If 0.3 * RED + 0.59 * GREEN + 0.11 * YELLOW > BW the pixel is - considered white color.

- -

2
- Colors are mapped as in 1, and use dithering of size as defined using - -d option. BWthreshold is used here as scaler.

-

- -The default is option 0.

- -

[-i] -
Invert the image, i.e. black -> white, white -> black.

- -

[-n] -
Nicer image. Uses double-density feature of Epson printer. This - takes more time (and kills your ink cartridge faster...) but results - are usually better.

- -

[-p printer] -
Under Unix, output goes to stdout by default; under DOS, the - default is LPT1:. With this switch you can specify the output - target.

- -

[-h] -
print one line of command line help, similar to Usage above.

-

- -

Notes:

- -The output has an aspect ratio of 1, so a square image will be square in -hardcopy as well.

- -The widest image can be printed is 640 pixels, on 8 inch paper. You -probably will need to flip wider images, if height is less than that: -`gifflip -r x29.gif | gif2epsn'. Wider -images will be clipped.

Options:

- -
[-q] -
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout - of running scan lines. Use -q- to invert.

- -

[-d dither] -
Sets size of dithering matrix, where dither can be - 2,3 or 4 only (for 2x2, 3x3 and 4x4 dithering matrices). Default is 2. - Note: the image will be dithered only if the mapping (see -m) - selected dithering mode.

- -

[-z zoom] -
Sets zoom factor of the image. Zoom factor should be - power of 2 up to 256. Default is 1 (no zoom).

- -

[-t bw] -
Sets threshold level for B&W mapping in percent. - This threshold level is used in the different mappings as selected via -m. - Default is 19%.

- -

[-m map] -
Select method to map colors to B&W. Mapping can be: - -
-
0
- Every non-background color is considered foreground (white). - -
1
- 0.3 * RED + 0.59 * GREEN + 0.11 * YELLOW > BWThreshold is considered white. - -
2
- Colors are mapped as in 1, and use dithering of size as defined using - -d option. BWthreshold is used here as scaler. -
- -Default is option 0, which is much faster than the other two.

- -

[-i] -
Invert the image, i.e. black -> white, white -> black.

- -

[-b] -
Disable beeps. Every time the image is complete, or a wrong key was - presses, sound is generated. The -b option disables that.

- -

[-h] -
Print one line of command line help, similar to Usage above.

- - -

Interactive mode:

- -Once the image is displayed, the program goes into an interactive mode -which recognizes the following commands: - -
-
C - get Color and position -
In this submenu, a cursor appears and the location and color of the - pixel underneath it are printed. The 4 arrows may be used (shifted for - faster movement) to move the cursor. Any other key will abort this - submode.

- - -

D - zoom Down -
Zoom down by factor of 2 unless current zoom factor is 1.

- -

H - Increase dither matrix size -
...unless current size is maximum (4), in which case size is set - to minimum (2).

- -

I - Invert -
Invert the image, i.e. white -> black, black -> white.

- -

M - Method -
Increment color -> BW mapping method, unless current method is maximum - (2), in which case method is set to minimum (0).

- -

R - Redraw -
Redraw the image.

- -

S - print Status -
Print status of image and program.

- -

U - zoom Up -
Zoom up by factor of 2 unless current zoom factor is 256.

- -

arrow keys -
The 4 arrow keys can be used to pan in the desired direction, if the image - overflows in that direction. If the image fits into the screen, arrow - keys are ignored. The panning steps are 1/2 screen if not on image end.

- -

SPC - abort -
Space bar may be used to abort current image drawing.

- -

ESC - abort -
Escape may be used to abort current image drawing.

The image format described in this document is + designed to support current and future image technology and will in + addition serve as a basis for future CompuServe graphics products. + + The main focus of this document is to provide the technical + information necessary for a programmer to implement GIF encoders and + decoders. As such, some assumptions are made as to terminology relavent + to graphics and programming in general. + + The first section of this document describes the GIF data format + and its components and applies to all GIF decoders, either as standalone + programs or as part of a communications package. Appendix B is a + section relavent to decoders that are part of a communications software + package and describes the protocol requirements for entering and exiting + GIF mode, and responding to host interrogations.

How images larger than the physical display are + handled is implementation dependent and can take advantage of hardware + characteristics (e.g. Macintosh scrolling windows). Otherwise images + can be clipped to the edges of the display. + + The value of 'pixel' also defines the maximum number of colors + within an image. The range of values for 'pixel' is 0 to 7 which + represents 1 to 8 bits. This translates to a range of 2 (B & W) to 256 + colors. Bit 3 of word 5 is reserved for future definition and must be + zero. + +Graphics Interchange Format (GIF) Page 5 + + + +Specification + + GLOBAL COLOR MAP + + The Global Color Map is optional but recommended for images where + accurate color rendition is desired. The existence of this color map is + indicated in the 'M' field of byte 5 of the Screen Descriptor. A color + map can also be associated with each image in a GIF file as described + later. However this global map will normally be used because of + hardware restrictions in equipment available today. In the individual + Image Descriptors the 'M' flag will normally be zero. If the Global + Color Map is present, it's definition immediately follows the Screen + Descriptor. The number of color map entries following a Screen + Descriptor is equal to 2**(# bits per pixel), where each entry consists + of three byte values representing the relative intensities of red, green + and blue respectively. The structure of the Color Map block is: + + bits + 7 6 5 4 3 2 1 0 Byte # + +---------------+ + | red intensity | 1 Red value for color index 0 + +---------------+ + |green intensity| 2 Green value for color index 0 + +---------------+ + | blue intensity| 3 Blue value for color index 0 + +---------------+ + | red intensity | 4 Red value for color index 1 + +---------------+ + |green intensity| 5 Green value for color index 1 + +---------------+ + | blue intensity| 6 Blue value for color index 1 + +---------------+ + : : (Continues for remaining colors) + + Each image pixel value received will be displayed according to its + closest match with an available color of the display based on this color + map. The color components represent a fractional intensity value from + none (0) to full (255). White would be represented as (255,255,255), + black as (0,0,0) and medium yellow as (180,180,0). For display, if the + device supports fewer than 8 bits per color component, the higher order + bits of each component are used. In the creation of a GIF color map + entry with hardware supporting fewer than 8 bits per component, the + component values for the hardware should be converted to the 8-bit + format with the following calculation: + + = *255/(2** -1) + + This assures accurate translation of colors for all displays. In + the cases of creating GIF images from hardware without color palette + capability, a fixed palette should be created based on the available + display colors for that hardware. If no Global Color Map is indicated, + a default color map is generated internally which maps each possible + incoming color index to the same hardware color index modulo where + is the number of available hardware colors. + +Graphics Interchange Format (GIF) Page 6 + + + +Specification + + IMAGE DESCRIPTOR + + The Image Descriptor defines the actual placement and extents of + the following image within the space defined in the Screen Descriptor. + Also defined are flags to indicate the presence of a local color lookup + map, and to define the pixel display sequence. Each Image Descriptor is + introduced by an image separator character. The role of the Image + Separator is simply to provide a synchronization character to introduce + an Image Descriptor. This is desirable if a GIF file happens to contain + more than one image. This character is defined as 0x2C hex or ',' + (comma). When this character is encountered between images, the Image + Descriptor will follow immediately. + + Any characters encountered between the end of a previous image and + the image separator character are to be ignored. This allows future GIF + enhancements to be present in newer image formats and yet ignored safely + by older software decoders. + + bits + 7 6 5 4 3 2 1 0 Byte # + +---------------+ + |0 0 1 0 1 1 0 0| 1 ',' - Image separator character + +---------------+ + | | 2 Start of image in pixels from the + +- Image Left -+ left side of the screen (LSB first) + | | 3 + +---------------+ + | | 4 + +- Image Top -+ Start of image in pixels from the + | | 5 top of the screen (LSB first) + +---------------+ + | | 6 + +- Image Width -+ Width of the image in pixels (LSB first) + | | 7 + +---------------+ + | | 8 + +- Image Height-+ Height of the image in pixels (LSB first) + | | 9 + +-+-+-+-+-+-----+ M=0 - Use global color map, ignore 'pixel' + |M|I|0|0|0|pixel| 10 M=1 - Local color map follows, use 'pixel' + +-+-+-+-+-+-----+ I=0 - Image formatted in Sequential order + I=1 - Image formatted in Interlaced order + pixel+1 - # bits per pixel for this image + + The specifications for the image position and size must be confined + to the dimensions defined by the Screen Descriptor.

If + the 'M' bit of byte 10 of the Image Descriptor is set, then a color map + follows the Image Descriptor that applies only to the following image. + At the end of the image, the color map will revert to that defined after + the Screen Descriptor. Note that the 'pixel' field of byte 10 of the + Image Descriptor is used only if a Local Color Map is indicated. This + defines the parameters not only for the image pixel size, but determines + the number of color map entries that follow. The bits per pixel value + will also revert to the value specified in the Screen Descriptor when + processing of the image is complete. + + RASTER DATA + + The format of the actual image is defined as the series of pixel + color index values that make up the image. The pixels are stored left + to right sequentially for an image row. By default each image row is + written sequentially, top to bottom. In the case that the Interlace or + 'I' bit is set in byte 10 of the Image Descriptor then the row order of + the image display follows a four-pass process in which the image is + filled in by widely spaced rows.

This may be a carriage + return entered at the keyboard or a mouse click. For interactive + applications this user action must be passed on to the host as a + carriage return character so that the host application can continue. + The decoding software will then typically leave graphics mode and resume + any previous process. + + GIF EXTENSION BLOCKS + + To provide for orderly extension of the GIF definition, a mechanism + for defining the packaging of extensions within a GIF data stream is + necessary. Specific GIF extensions are to be defined and documented by + CompuServe in order to provide a controlled enhancement path. + + GIF Extension Blocks are packaged in a manner similar to that used + by the raster data though not compressed. The basic structure is: + + 7 6 5 4 3 2 1 0 Byte # + +---------------+ + |0 0 1 0 0 0 0 1| 1 '!' - GIF Extension Block Introducer + +---------------+ + | function code | 2 Extension function code (0 to 255) + +---------------+ ---+ + | byte count | | + +---------------+ | + : : +-- Repeated as many times as necessary + |func data bytes| | + : : | + +---------------+ ---+ + . . . . . . + +---------------+ + |0 0 0 0 0 0 0 0| zero byte count (terminates block) + +---------------+ + + A GIF Extension Block may immediately preceed any Image Descriptor + or occur before the GIF Terminator. + + All GIF decoders must be able to recognize the existence of GIF + Extension Blocks and read past them if unable to process the function + code. This ensures that older decoders will be able to process extended + GIF image files in the future, though without the additional + functionality. + +Graphics Interchange Format (GIF) Page 9 + +Appendix A - Glossary + + GLOSSARY + +Pixel - The smallest picture element of a graphics image. This usually + corresponds to a single dot on a graphics screen. Image resolution is + typically given in units of pixels. For example a fairly standard + graphics screen format is one 320 pixels across and 200 pixels high. + Each pixel can appear as one of several colors depending on the + capabilities of the graphics hardware. + +Raster - A horizontal row of pixels representing one line of an image. A + typical method of working with images since most hardware is oriented to + work most efficiently in this manner. + +LSB - Least Significant Byte. Refers to a convention for two byte numeric + values in which the less significant byte of the value preceeds the more + significant byte. This convention is typical on many microcomputers. + +Color Map - The list of definitions of each color used in a GIF image. + These desired colors are converted to available colors through a table + which is derived by assigning an incoming color index (from the image) + to an output color index (of the hardware). While the color map + definitons are specified in a GIF image, the output pixel colors will + vary based on the hardware used and its ability to match the defined + color. + +Interlace - The method of displaying a GIF image in which multiple passes + are made, outputting raster lines spaced apart to provide a way of + visualizing the general content of an entire image before all of the + data has been processed. + +B Protocol - A CompuServe-developed error-correcting file transfer protocol + available in the public domain and implemented in CompuServe VIDTEX + products. This error checking mechanism will be used in transfers of + GIF images for interactive applications. + +LZW - A sophisticated data compression algorithm based on work done by + Lempel-Ziv & Welch which has the feature of very efficient one-pass + encoding and decoding. This allows the image to be decompressed and + displayed at the same time. The original article from which this + technique was adapted is: + + Terry A. Welch, "A Technique for High Performance Data + Compression", IEEE Computer, vol 17 no 6 (June 1984) + + This basic algorithm is also used in the public domain ARC file + compression utilities. The CompuServe adaptation of LZW for GIF is + described in Appendix C. + +Graphics Interchange Format (GIF) Page 10 + + + +Appendix B - Interactive Sequences + + GIF Sequence Exchanges for an Interactive Environment + + The following sequences are defined for use in mediating control + between a GIF sender and GIF receiver over an interactive communications + line. These sequences do not apply to applications that involve + downloading of static GIF files and are not considered part of a GIF + file. + + GIF CAPABILITIES ENQUIRY + + The GCE sequence is issued from a host and requests an interactive + GIF decoder to return a response message that defines the graphics + parameters for the decoder. This involves returning information about + available screen sizes, number of bits/color supported and the amount of + color detail supported. The escape sequence for the GCE is defined as: + + ESC [ > 0 g (g is lower case, spaces inserted for clarity) + (0x1B 0x5B 0x3E 0x30 0x67) + + GIF CAPABILITIES RESPONSE + + The GIF Capabilities Response message is returned by an interactive + GIF decoder and defines the decoder's display capabilities for all + graphics modes that are supported by the software. Note that this can + also include graphics printers as well as a monitor screen. The general + format of this message is: + + #version;protocol{;dev, width, height, color-bits, color-res}... + + '#' - GCR identifier character (Number Sign) + version - GIF format version number; initially '87a' + protocol='0' - No end-to-end protocol supported by decoder + Transfer as direct 8-bit data stream. + protocol='1' - Can use an error correction protocol to transfer GIF data + interactively from the host directly to the display. + dev = '0' - Screen parameter set follows + dev = '1' - Printer parameter set follows + width - Maximum supported display width in pixels + height - Maximum supported display height in pixels + color-bits - Number of bits per pixel supported. The number of + supported colors is therefore 2**color-bits. + color-res - Number of bits per color component supported in the + hardware color palette. If color-res is '0' then no + hardware palette table is available. + + Note that all values in the GCR are returned as ASCII decimal + numbers and the message is terminated by a Carriage Return character. + +Graphics Interchange Format (GIF) Page 11 + + + +Appendix B - Interactive Sequences + + The following GCR message describes three standard EGA + configurations with no printer; the GIF data stream can be processed + within an error correcting protocol: + + #87a;1 ;0,320,200,4,0 ;0,640,200,2,2 ;0,640,350,4,2 + + ENTER GIF GRAPHICS MODE + + Two sequences are currently defined to invoke an interactive GIF + decoder into action. The only difference between them is that different + output media are selected. These sequences are: + + ESC [ > 1 g Display GIF image on screen + (0x1B 0x5B 0x3E 0x31 0x67) + ESC [ > 2 g Display image directly to an attached graphics printer. + The image may optionally be displayed on the screen as + well. + (0x1B 0x5B 0x3E 0x32 0x67) + + Note that the 'g' character terminating each sequence is in lower + case. + + INTERACTIVE ENVIRONMENT + + The assumed environment for the transmission of GIF image data from + an interactive application is a full 8-bit data stream from host to + micro. All 256 character codes must be transferrable. The establishing + of an 8-bit data path for communications will normally be taken care of + by the host application programs. It is however up to the receiving + communications programs supporting GIF to be able to receive and pass on + all 256 8-bit codes to the GIF decoder software. + +Graphics Interchange Format (GIF) Page 12 + + + +Appendix C - Image Packaging & Compression + + The Raster Data stream that represents the actual output image can + be represented as: + + 7 6 5 4 3 2 1 0 + +---------------+ + | code size | + +---------------+ ---+ + |blok byte count| | + +---------------+ | + : : +-- Repeated as many times as necessary + | data bytes | | + : : | + +---------------+ ---+ + . . . . . . + +---------------+ + |0 0 0 0 0 0 0 0| zero byte count (terminates data stream) + +---------------+ + + The conversion of the image from a series of pixel values to a + transmitted or stored character stream involves several steps. In brief + these steps are: + + 1. Establish the Code Size - Define the number of bits needed to + represent the actual data. + 2. Compress the Data - Compress the series of image pixels to a series + of compression codes. + 3. Build a Series of Bytes - Take the set of compression codes and + convert to a string of 8-bit bytes. + 4. Package the Bytes - Package sets of bytes into blocks preceeded by + character counts and output. + +ESTABLISH CODE SIZE + + The first byte of the GIF Raster Data stream is a value indicating + the minimum number of bits required to represent the set of actual pixel + values. Normally this will be the same as the number of color bits. + Because of some algorithmic constraints however, black & white images + which have one color bit must be indicated as having a code size of 2. + This code size value also implies that the compression codes must start + out one bit longer. + +COMPRESSION + + The LZW algorithm converts a series of data values into a series of + codes which may be raw values or a code designating a series of values. + Using text characters as an analogy, the output code consists of a + character or a code representing a string of characters. + +Graphics Interchange Format (GIF) Page 13 + +Appendix C - Image Packaging & Compression + + The LZW algorithm used in GIF matches algorithmically with the + standard LZW algorithm with the following differences: + + 1. A special Clear code is defined which resets all + compression/decompression parameters and tables to a start-up state. + The value of this code is 2**. For example if the code + size indicated was 4 (image was 4 bits/pixel) the Clear code value + would be 16 (10000 binary). The Clear code can appear at any point + in the image data stream and therefore requires the LZW algorithm to + process succeeding codes as if a new data stream was starting. + Encoders should output a Clear code as the first code of each image + data stream. + + 2. An End of Information code is defined that explicitly indicates the + end of the image data stream. LZW processing terminates when this + code is encountered. It must be the last code output by the encoder + for an image. The value of this code is +1. + + 3. The first available compression code value is +2. + + 4. The output codes are of variable length, starting at +1 + bits per code, up to 12 bits per code. This defines a maximum code + value of 4095 (hex FFF). Whenever the LZW code value would exceed + the current code length, the code length is increased by one. The + packing/unpacking of these codes must then be altered to reflect the + new code length. + +BUILD 8-BIT BYTES + + Because the LZW compression used for GIF creates a series of + variable length codes, of between 3 and 12 bits each, these codes must + be reformed into a series of 8-bit bytes that will be the characters + actually stored or transmitted. This provides additional compression of + the image. The codes are formed into a stream of bits as if they were + packed right to left and then picked off 8 bits at a time to be output. + Assuming a character array of 8 bits per character and using 5 bit codes + to be packed, an example layout would be similar to: + + byte n byte 5 byte 4 byte 3 byte 2 byte 1 + +-.....-----+--------+--------+--------+--------+--------+ + | and so on |hhhhhggg|ggfffffe|eeeedddd|dcccccbb|bbbaaaaa| + +-.....-----+--------+--------+--------+--------+--------+ + + Note that the physical packing arrangement will change as the + number of bits per compression code change but the concept remains the + same. + +PACKAGE THE BYTES + + Once the bytes have been created, they are grouped into blocks for + output by preceeding each block of 0 to 255 bytes with a character count + byte. A block with a zero byte count terminates the Raster Data stream + for a given image. These blocks are what are actually output for the + +Graphics Interchange Format (GIF) Page 14 + + + +Appendix C - Image Packaging & Compression + + GIF image. This block format has the side effect of allowing a decoding + program the ability to read past the actual image data if necessary by + reading block counts and then skipping over the data. + +Graphics Interchange Format (GIF) Page 15 + + + + +Appendix D - Multiple Image Processing + + Since a GIF data stream can contain multiple images, it is + necessary to describe processing and display of such a file. Because + the image descriptor allows for placement of the image within the + logical screen, it is possible to define a sequence of images that may + each be a partial screen, but in total fill the entire screen. The + guidelines for handling the multiple image situation are: + + 1. There is no pause between images. Each is processed immediately as + seen by the decoder. + + 2. Each image explicitly overwrites any image already on the screen + inside of its window. The only screen clears are at the beginning + and end of the GIF image process. See discussion on the GIF + terminator. diff -Nru giflib-4.1.6/doc/gifasm.html giflib-5.0.5-2/doc/gifasm.html --- giflib-4.1.6/doc/gifasm.html 2005-10-10 06:22:21.000000000 +0000 +++ giflib-5.0.5-2/doc/gifasm.html 1970-01-01 00:00:00.000000000 +0000 @@ -1,59 +0,0 @@ - - - -gifasm - - - -Go to index page. - -

gifburst

- -The gifburst program takes a named GIF file and breaks it into equal-sized -tiles. This is useful if a GIF is too large for your viewer, so you have -to look at it in sections.

- -

Usage:

- -
-gifburst [-s n] [-p b] gif-file
-
- -

Memory required:

- -Proportional to the size of the largest pasted image. - -

Options:

- -
[-s nnn] -
Specify the number of pieces. Valid values are presently 4 (2x2) - and 6 (2x3). Default is 4. - -
[-p nnn] -
Specify the number of pixels of overlap between interior boundaries - of pieces. Default 20. - -

Note:

- -The gifburst program is written on Perl, using the C utilities. You must have -both the giflib utilities and Perl installed to run it.

gifclip

- -A program to clip images in GIF files. Only one image in a GIF file can be -modified at a time. Neither the image position on screen nor the screen size -is modified (use gifpos for that).

- -

Usage:

- -
-gifclip [-q] [-i Xmin Ymin Xmax Ymax] [-n n Xmin Ymin Xmax Ymax] [-c] [-h] gif-file
-
- -If no gif-file is given, GifClip will try to read a GIF file from stdin.

- -

Memory required:

- -Line. - -

Options:

- -
-
[-q] -
Quiet mode. Default off on MSDOS, on under UNIX. Controls printout - of running scan lines. Use -q- to invert.

- -

[-i Xmin Ymin Xmax Ymax] -
Clip first image to the dimensions as specified - by the 4 coordinates (Xmin Ymin Xmax Ymax) of a box clipping region.

- - For example: '-i 11 22 33 44' will crop the box from top left [11,22] - to bottom right [33,44] out of the first image.

- - If the first parameter is bigger than third one (Xmin > Xmax) they are - swapped. Same for Y.

- - The dimensions of the clipped image must be confined to original image - width and height. Note the clipped image includes both the min & max - boundary; an image of width W can have coordinates 0 to W-1 (zero based).

- - Only one of -i or -n can be specified.

- -

[-n n Xmin Ymin Xmax Ymax] -
Same as -i above but for the nth image: - `-n 1 11 22 33 44' is exactly the same as the example in -i. Only one of - -i or -n can be specified.

- -

[-c] -
Complement. This removes horizontal and/or vertical bands of the - image. For example `-c -i 638 3 658 13' would remove a horizontal band - 11 pixels deep beginning at raster line 3, and a vertical band 21 pixels - right beginning at pixel 658.

- -

[-h] -
Print one line of command line help, similar to Usage above.

-

- -Note: all coordinates are 0-based --- the top left corner is (0, 0).

- -

[-s] -
Select the global screen color map.

- -

[-l map] -
Load color map from this file instead of selected color map.

- -

[-t trans] -
Change color index values. The change is made to both - the selected color table and the raster bits of the selected image. A - translation file is a list of pairs of `before' and `after' index values. - At present, the `before' index values must be in ascending order starting - from 0.

- -

[-g Gamma] -
Apply gamma correction to selected color map.

- -

[-i image] -
Select the color map of the numbered image.

- -

[-h] -
Print one command line help, similar to Usage above.

-

- -

Notes:

- -
    -
  • -The default operation is to dump out the selected color map in text -format.

    - -

  • -The file to load/dump is simply one color map entry per line. Each such -entry line has four integers: "ColorIndex Red Green Blue", where color -index is in ascending order starting from 1.

gifcompose

- -The gifcompose program uses the GIFLIB utility tools to support a minilanguage -for describing GIF pasteup sequences.

- -

Usage:

- -
-gifcompose [-v] <specfile
-
- -

Specification Syntax

- -The gifcompose tool takes a series of text lines and interprets them as -commands to do pasteup operations. The commands are:

- -

Generators

- -
-
gif <name>
- Paste in <name>.gif

- -

raw <name> <width> <height>
- Paste in the given raw-format file (no suffix supplied). Raw format - is a stream of 8-bit indices into the EGA color map. Accordingly, the - width and height must be specified, and the source must be exactly - width times height bytes long.

- -

rgb <name> <width> <height>
- Paste in the given RGB-format file (no suffix supplied). Raw format - is a stream of 24-bit color values. Accordingly, the width and height - must be specified, and the source must be exactly 3 times width times - height bytes long.

- -

rle <name>
- Paste in the given RLE-format file (no suffix supplied). This converts - the Utah Raster Kit format to GIF.

- -

text <text> [foreground <index>] [color <r> <g> <b>]
- Copy 8x8 monospace font, with transparent background and index 1 as - foreground. If the text string contains whitespaces, they must be - escaped or the string must be quoted (shell conventions).

- - The optional suffix `foreground <n>' sets the foreground color index. - The optional suffix `color <r> <g> <b>' sets the RGB color to be used - for the foreground index.

-

- -Each generator operation may be followed by any combination of the -following suffixes: - -

Modifiers

- -
at <x> <y>
- Place the image at the given (upper-left-hand-corner) coordinates - in the pasted-up result.

- -

clip <name> <top-x> <top-y> <bottom-x> <bottom-y>
- Clip image using the given rectange, paste it onto.

- -

xflip
- Flip the image around the X axis before placing it.

- -

yflip
- Flip the image around the Y axis before placing it.

- -

left
- Rotate the image 90 degrees counterclockwise before placing it.

- -

right
- Rotate the image 90 degrees clockwise before placing it.

- -

Target Operations

- -
screen size <x-size> <y-size>
- Set the global screen size of the final image.

- -

screen position <x> <y>
- Set the global screen position of the final image.

- -

Comments

- -Comments or comment lines may be preceded with `#' and will be ignored.

- -

Memory required:

- -Proportional to the size of the largest pasted image.

- -

Options:

- -
-
[-v] -
Emit a report on each composition action to stderr as it happens. -
- -

Bugs:

- -The suffix sequence `left left' sometimes mysteriously fails to work, -probably due to some restriction in gifflip.

- -No support for resizing or odd-angle rotations yet.

- -The `color' suffix of text is a no-op, because the present version of -gifovly throws away color tables.

- -Error checking is rudimentary.

The GIFLIB Library

- -
-Gershon Elber, May 1991
-Eric S. Raymond, Sep 1992
-Toshio Kuratomi, May 2004
-
- -The Graphics Interchange Format(c) is the Copyright property of -CompuServe Incorporated. GIF(sm) is a Service Mark property of CompuServe -Incorporated.

- -Gershon wrote: "This library was written because I couldn't find -anything similar and I wanted one. I was inspired by the RLE Utah tool kit, -which I hoped to port to an IBM PC, but found it to be too machine specific, -and its compression ratio too low. I compromised on the GIF format, but I am -not sure how long 8 bits per pixel will be enough."

- -This document explains the GIF library code in directory `lib'. The -code is collected into libgif.a which is used in all the utilities in -`util'. It can be used in any application needs to read/write the GIF -file format. This document does not explain the GIF file -format and assumes you know it, at least to the level of the GIF file -structure.

- -When a GIF file is opened, a GIF file descriptor is created which -is a pointer to GifFileType structure as follows:

- -


-typedef struct GifFileType {
-    int SWidth, SHeight,			       /* Screen dimensions. */
-	SColorResolution, 		 /* How many colors can we generate? */
-	SBackGroundColor;		/* I hope you understand this one... */
-    ColorMapObject *SColorMap;			      /* NULL if not exists. */
-    int ImageCount;				  /* Number of current image */
-    GifImageDesc Image;			   /* Block describing current image */
-    struct SavedImage *SavedImages;	/* Use this to accumulate file state */
-    VoidPtr Private;	  /* The regular user should not mess with this one! */
-} GifFileType;
-
- -This structure was copied from gif_lib.h - the header file for the GIF -library. Any application program that uses the libgif.a library should -include it. Members beginning with S refer to GIF Screen; others hold -properties of the current image (a GIF file may have more than one image) -or point to allocated store used by various routines.

- -The user almost never writes into this structure (exception: it may -occasionally useful to alter things in the SavedImages array), but can read -any of these items at any time it is valid (image information is invalid -until first image was read/write).

- -As the library needs to keep its own internal data, a Private pointer -to hidden data is included. Applications should ignore this item.

- -The library has no static data. This means that it is fully reentrant -and any number of GIF files (up to memory limits) can be opened for -read/write. Instead of the static data, internal structure pointed by the -Private pointer is used.

- -The library allocates its own memory dynamically, on opening of files, -and releases that once closed. The user is never required to allocate -any memory for any of the functions of this library nor to free them -directly.

- -In order to reduce disk access, the file buffer is increased to -FILE_BUFFER_SIZE (defined in gif_lib.h). The library was compiled in large -model on the PC as the memory allocated per file is quite big: about 17k for -decoding (DGIF_LIB.C), and 32k for encoding (EGIF_LIB.C), excluding the -FILE_BUFFER_SIZE.

- -Here is a module summary:

- -

-
egif_lib.c
Encoding routines, all prefixed with E.

- -

dgif_lib.c
Decoding routines, all prefixed with D.

- -

dev2gif.c
Routines to convert specific device buffers into GIF files.

- -

gifalloc.c
Routines for colormap handling and GIF record allocation.

- -

gif_font.c
The 8x8 font table for the GIF utility font.

- -

gif_err.c
Error handler for the library.

-

- -The library includes a sixth file of hash-function code which is accessed -internally only.

- -

Most of the routines return GIF_ERROR (see gif_lib.h) if something -went wrong, GIF_OK otherwise. After an error return, the code in the -gif_err.c module can be used to do something about it.

- -In addition, a module to parse command line arguments is supplied. -This module is called getarg.c and its headers are in getarg.h. See the header -of getarg.c for details on its usage.

- -

Decoding (dgif_lib.c)

- -The following functions are used to set up input from a GIF:

- -


-GifFileType *DGifOpenFileName(char *GifFileName)
-
- -Open a new GIF file using the given GifFileName, and read its Screen -information. - - -If any error occurs, NULL is returned and the error handler can be -used to get the exact error (see gif_err.c). - - -The file is opened in binary mode, and its buffer size is set to -FILE_BUFFER_SIZE bytes. - - -

-GifFileType *DGifOpenFileHandle(int GifFileHandle)
-
- -Open a new GIF file using the given GifFileHandle, and read its Screen -information.

- -If any error occurs, NULL is returned and the error handler can be -used to get the exact error (see gif_err.c).

- -The file is opened in binary mode, and its buffer size is set to -FILE_BUFFER_SIZE bytes.

- -Once you have acquired a handle on a GIF, there are two ways to read it in. -The high-level function - -


-int DGifSlurp(GifFileType)
-
- -reads the rest of a complete (possibly multi-image) GIF file from the -indicated file handle into in-core allocated structures. It returns -GIF_OK on success, GIF_ERROR on failure.

- -Once you have done this, all image, raster, and extension-block data in the -GIF is accessable in the SavedImages member (see the structures in fif_lib.h). -When you have modified the image to taste, write it out with EGifSpew().

- -If you are handling large images on a memory-limited machine, you may need -to use the following functions for sequential read.

- -


-int DGifGetScreenDesc(GifFileType *GifFile)
-
- -Reads the screen information into the GifFile structure. Note this -routine is automatically called once a file is opened, and therefore -usually need not be called explicitly.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int DGifGetRecordType(GifFileType *GifFile, GifRecordType *GifType)
-
- -As the GIF file can have different records in arbitrary order, this -routine should be called once the file was open to detect the next -record type, and act upon it. It can return these types in GifType:

- -

-
1. UndefinedRecordType
something is wrong!

- -

2. ScreenDescRecordType
screen information. As the screen info - is automatically read in when the file is open, this should - not happen.

- -

3. ImageDescRecordType
next record is an image descriptor.

- -

4. ExtensionRecordType
next record is extension block.

- -

5. TerminateRecordType
last record reached, can close the file.

-

-The first two types can usually be ignored. The function -returns GIF_ERROR if something went wrong, GIF_OK otherwise. - -

-int DGifGetImageDesc(GifFileType *GifFile)
-
- -Reads image information into the GifFile structure. -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int DGifGetLine(GifFileType *GifFile, PixelType *GifLine, int GifLineLen)
-
- -Load a block of pixels from the GIF file. The line can be -of any length. More than that, this routine may be interleaved with -DGifGetPixel until all pixels have been read.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -

-int DGifGetPixel(GifFileType *GifFile, PixelType GifPixel)
-
- -Loads one pixel from the GIF file. This routine may be interleaved -with DGifGetLine, until all pixels are -read. Because of the overhead per each call, use of this routine is -not recommended.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int DGifGetComment(GifFileType *GifFile, char *GifComment)
-
- -Load a comment from the GIF file. Because DGifGetRecordType will -only tell if the record is of type extension, this routine should be -called iff it is known %100 that is must be a comment.

- -For the definition of a comment, see EGifPutComment. Returns GIF_ERROR if -something went wrong, GIF_OK otherwise.

- -


-int DGifGetExtension(
-        GifFileType *GifFile,
-        int *GifExtCode,
-        ByteType **GifExtension)
-
- -Loads an extension block from the GIF file. Extension blocks -are optional in GIF files. This routine should be followed by -DGifGetExtensionNext.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int DGifGetExtensionNext(GifFileType *GifFile, ByteType **GifExtension)
-
- -As extensions may contain more than one block, use this routine to -continue after DGifGetExtension, until *GifExtension is NULL.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- - -


-int DGifGetCode(
-        GifFileType *GifFile, 
-        int *GifCodeSize, ByteType **GifCodeBlock)
-
- -It sometimes may be desired to read the compressed code as is -without decoding it. This routine does exactly that (with -DGifGetCodeNext), and can be used instead of DGifGetLine.

- -This compressed code information can be written out using the -EGifPutCode/EGifPutCodeNext sequence (see gifpos.c for example). -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int DGifGetCodeNext(GifFileType *GifFile, ByteType **GifCodeBlock)
-
- -See DGifGetCode above.

- -


-int DGifGetLZCodes(GifFileType *GifFile, int *GifCode)
-
- -This routine can be called instead of DGifGetLine/DGifGetPixel or -DGifGetCode/DGifGetCodeNext to get the 12 bits LZ codes of the images. -It will be used mainly for debugging purposes (see GifText.c for -example).

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int DGifCloseFile(GifFileType *GifFile)
-
- -Close GIF file and free all memory allocated for it. GifFile should -not be used after this routine has been called.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -

Encoding (egif_lib.c)

- -There are two ways to write out a GIF. The high-level function

- -

-int EGifSpew(GifFileType *GifFile, int GifFileHandle)
-
- -Writes a complete (possibly multi-image) GIF file to the indicated file -handle from in-core allocated structures created by a previous DGifSlurp() -or equivalent operations. Its arguments are a GIF file descriptor (as -above) and an ordinary output file descriptor.

- -The file is written with a GIF87 stamp unless it contains one of the four -special extension blocks defined in GIF89, in which case it is written -with a GIF89 stamp.

- -If you are handling large images on a memory-limited machine, you may need -to use the following functions for sequential write.

- -


-GifFileType *EGifOpenFileName(char *GifFileName, int GifTestExistance)
-
- -Open a new GIF file using the given GifFileName. If GifTestExistance -is TRUE, and file exists, the file is not destroyed, and NULL -returned.

- -If any error occurs, NULL is returned and the error handler can be -used to get the exact error (see gif_err.c).

- -The file is opened in binary mode, and its buffer size is set to -FILE_BUFFER_SIZE bytes.

- -


-GifFileType *EGifOpenFileHandle(int GifFileHandle)
-
- -Open a new GIF file using the given GifFileHandle.

- -If any error occurs, NULL is returned and the error handler can be -used to get the exact error (see gif_err.c).

- -The file is opened in binary mode, and its buffer size is set to -FILE_BUFFER_SIZE bytes.

- -


-void EGifSetGifVersion(char *Version)
-
- -Sets the GIF version of all files opened, until another call to this -routine is made. Version is a 3 characters string of the form "87a" -or "89a". No test is made to validate this string.

- -


-int EGifPutScreenDesc(GifFileType *GifFile,
-        int GifWidth, int GifHeight,
-        int GifColorRes, int GifBackGround,
-        ColorMapObject *GifColorMap)
-
- -Update the GifFile Screen parameters, in GifFile structure and in -the real file. If error occurs, returns GIF_ERROR (see gif_lib.h), -otherwise GIF_OK.

- -This routine should be called immediately after the GIF file was -opened.

- -


-int EGifPutImageDesc(GifFileType *GifFile,

- -


-int EGifPutLine(GifFileType *GifFile, PixelType *GifLine, int GifLineLen)
-
- -Dumps a block of pixels out to the GIF file. The slab can be -of any length. More than that, this routine may be interleaved with -, until all pixels have been sent.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int EGifPutPixel(GifFileType *GifFile, PixelType GifPixel)
-
- -Dumps one pixel to the GIF file. This routine may be interleaved with -EGifPutLine, until all pixels were sent. -Because of the overhead for each call, use of this routine is not -recommended.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int EGifPutComment(GifFileType *GifFile, char *GifComment)
-
- -Uses extension GIF records to save a string as a comment is the file. -The extension code is 'C' (for Comment).

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int EGifPutExtension(
-        GifFileType *GifFile,
-        int GifExtCode,
-        int GifExtLen,
-        void *GifExtension)
-
- -Dumps the given extension block into the GIF file. Extension blocks -are optional in GIF file. Extension blocks of more than 255 bytes or -more than one block are not supported in this function. Please use -EGifPutExtensionFirst, EGifPutExtensionNext, and EGifPutExtensionLast -if your extension blocks may fall into this category.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int EGifPutExtensionFirst(
-        GifFileType * GifFile,
-        int GifExtCode,
-        int GifExtLen,
-        const VoidPtr GifExtension)
-
-Dumps the beginning of a GIF extension block to a GIF file. Extension blocks -are optional in GIF files. This function outputs the meta information -necessary to a GIF extension block and the extension data described in the -GifExtension argument.

- -Further blocks of the GIF Extension should be dumped using -EGifPutExtensionNext. When finished with this extension block, -EGifPutExtensionLast should be called to output the block termination.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int EGifPutExtensionNext(
-        GifFileType * GifFile,
-        int GifExtCode,
-        int GifExtLen,
-        const VoidPtr GifExtension)
-
-Dumps a subblock of a GIF extension to a GIF File. Extension blocks are -optional in GIF files. This function will write the Extension Data in -GifExtension to the file as a subblock of the preceding Extension Block. -Repeat calling of this function until all data subblocks have been output.

- -Note that EGifPutExtensionFirst needs to be called before any calls to this -function. EGifPutExtensionLast should be called to finish the Extension -block after all data subblocks have been output.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int EGifPutExtensionLast(
-        GifFileType * GifFile,
-        int GifExtCode,
-        int GifExtLen,
-        const VoidPtr GifExtension)
-
-Dumps an optional GIF extension data subblock and the GIF extension block -terminator to a GIF File. Extension blocks are optional in GIF files. This -function will write the Extension Data in GifExtension to the file as a -subblock of the preceding Extension Block. Then it will output the GIF -extension block terminator to end the current Extension block. As a special -case, if GifExtLen is zero, the function will assume there isn't another -data block to output and will simply write the block terminator.

- -Note that a call to EGifPutExtensionFirst is needed to open the GIF -Extension Block prior to calling this function.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int EGifPutCode(
-        GifFileType *GifFile,
-        int *GifCodeSize,
-        ByteType **GifCodeBlock)
-
- -It sometimes may be desired to write the compressed code as is -without decoding it. For example a filter for a GIF file that change -only screen size (GifPos), does not need the exact pixel values. -Piping out the compressed image as is makes this process much -faster.

- -This routine does exactly that (with EGifPutCodeNext), and can be -used instead of EGifPutLine. You'll usually use this with the -DGifGetCode/DgifGetCodeNext routines, which reads the compressed -code, while EGifPutCode/EGifPutCodeNext write it out. See gifpos.c -for example.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -


-int EGifPutCodeNext(GifFileType *GifFile, ByteType **GifCodeBlock)
-
- -See EGifPutCode above.

- -


-int EGifCloseFile(GifFileType *GifFile)
-
- -Close a GIF file and free all memory allocated for it. gif-file$ -should not be used, once this routine was called.

- -Returns GIF_ERROR if something went wrong, GIF_OK otherwise.

- -

Color map handling and allocation routines

- -

-ColorMapObject *MakeMapObject(int ColorCount, GifColorType *ColorMap)
-
- -Allocate storage for a color map object with the given number of -RGB triplet slots. If the second argument is non-NULL, initialize -the color table portion of the new map from it. Returns NULL if -memory is exhausted or if the size is not a power of 2 <= 256.

- -


-void FreeMapObject(ColorMapObject *Object)
-
- -Free the storage occupied by a ColorMapObject that is no longer needed.

- -


-ColorMapObject *UnionColorMap(
-        ColorMapObject *ColorIn1, ColorMapObject *ColorIn2,
-        GifPixelType ColorTransIn2[])
-
- -Create the union of two given color maps and return it. If the result -won't fit into 256 colors, NULL is returned, the allocated union -otherwise. ColorIn1 is copied as it to ColorUnion, while colors from -ColorIn2 are copied iff they didn't exist before. ColorTransIn2 maps -the old ColorIn2 into ColorUnion color map table.

- -


-SavedImage *GifAttachImage(GifFileType *GifFile)
-
- -Add an image block to the SavedImages array. The image block is -initially zeroed out. This image block will be seen by any following -EGifSpew() calls. - - -

The GIF Utility Font

- -The 8x8 utility font used in text2gif and gifcolor lives in the library -module gif_font.c, in a table called AsciiTable. The library header file -includes suitable externs and defines.

- -The GIF utility font support includes entry points for drawing legends -on in-core images, drawing boxes and rectangles, and boxing text. -These entry points are as follows:

- -


-void DrawText(
-        SavedImage *Image,
-        const int x, const int y,
-        const char *legend,
-        const int color)
-
- -Draw text using the 8x8 utility font on the saved image. Upper left -corner of the text is at image pixel (x, y). Use the specified -color index.

- -


-void DrawBox(SavedImage *Image,
-        const int x, const int y,
-        const int w, const int h,
-        const int color)
-
- -Draw a box on the saved image. Upper left corner of the box is at -image pixels (x, y), width is w, height is h. Use the specified color -index.

- -


-void DrawRectangle(SavedImage *Image,
-        const int x, const int y,
-        const int w, const int h,
-        const int color)
-
- -Draw a (filled) rectangle on the saved image. Upper left corner of -the box is at image pixels (x, y), width is w, height is h. Use the -specified color index.

- -


-void DrawBoxedText(SavedImage *Image,
-        const int x, const int y,
-        const char *legend,
-        const int border,
-        const int bg, const int fg)
-
- -Draw text on a filled rectangle. The rectangle will be sized to fit -the text, with upper left hand corner at (x, y) on the saved image. -The `border' argument specifies a pixel margin around the text. The -`bg' argument is the color table index to fill the rectangle with; -`fg' is the color table index to draw the text with.

- -This function interprets some characters in the legend string -specially. A tab (\t) is interpreted as a command to center the -following text in the box. A carriage return (\r) is interpreted -as a request for a line break.

- -

Error Handling (egif_lib.c)

- -

-void PrintGifError(void)
-
- -Print a one-line diagnostic on the last giflib error to stderr.

- -


-int GifLastError(void)
-
- -Return the number of the last giflib error, and clear the error. -The error types are defined in gif_lib.h.

- -Note it is the user's responsibility to call the file closing -routine, so the file will be closed (if was opened), and allocated -memory will be released.

- -

Device Specific (XXX2gif.c)

- -

-int DumpScreen2Gif(char *FileName, int ReqGraphDriver, int ReqGraphMode1,
-						       int ReqGraphMode2)
-
- -Dumps the whole device buffer as specified by GraphDriver and -GraphMode (as defined in TC 2.0 graphics.h) into FileName as GIF file. -Current devices supported:

- -

-	1. Hercules.
-
-	2. EGA, EGA64, EGAMONO (all modes - see TC graphics.h).
-
-	3. VGA (all modes - see TC graphics.h).
-
-	4. SVGA_SPECIAL. This mode is special and not supported by Borland
-	   graphics.h. ReqGraphDriver must be equal to 999, and ReqGraphMode
-	   is ignored. This modes assumes 800 by 600 in 16 colors.
-	  Returns GIF_ERROR if something went wrong, GIF_OK otherwise.
-
-	5. SGI 4D using gl graphic library - window dump.
-
-	6. X11 window dump.
-
- - -

Command Line Parsing

- -

-int GAGetArgs(int argc, char **argv, char *CtrlStr, ...)
-
- -Main routine of this module. Given argc & argv as received by -the main procedure, the command line CtrlStr, and the addresses of -all parameters, parse the command line, and update the parameters.

- -The CtrlStr defines what types of variables should follow. Look at the -beginning of getarg.c for exact usage.

- -Returns 0 if successful, error number (as defined by getarg.h) otherwise.

- -


-void GAPrintErrMsg(int Error)
-
- -If an error occurred in GAGetARgs, this routine may be used to print -one line diagnostic to stderr.

- -


-void GAPrintHowTo(char *CtrlStr)
-
- -Given the same CtrlStr as for GAGetArgs, can be used to print a one line -'how to use'.

- -

Skeletons of GIF filters

- -If you are developing on a virtual-memory OS such as most flavors of -UNIX, or are otherwise sure of having enough memory to keep all of GIFs you -need to operate in core, writing a filter is trivial. See the file -gifspnge.c in util.

- -A sequential filter skeleton will usually look like the example file -giffiltr.c in util.

- -

Please look at the utilities in the util directory for more ideas once -you feel comfortable with these skeletons. Also try to follow the coding -standards of this package if you want the maintainer to officially add your new -utility to it.

The GIFLIB Library + + + + + Eric + Steven + Raymond + + + Thyrsus Enterprises +
+ &email; +
+ + + + 2012 + Eric S. Raymond + + + + + + +Introduction + +The Graphics Interchange Format(c) is the Copyright property of +CompuServe Incorporated. GIF(sm) is a Service Mark property of CompuServe +Incorporated. + +This document explains the GIF library code in directory `lib'. The +code is collected into a service library which is used in all the utilities in +`util'. It can be used in any application needs to read/write the GIF +file format. This document does not explain the GIF file +format and assumes you know it, at least to the level of the GIF file +structure. + + +Credit and Blame + +Gershon wrote: "This library was written because I couldn't find +anything similar and I wanted one. I was inspired by the RLE Utah tool kit, +which I hoped to port to an IBM PC, but found it to be too machine specific, +and its compression ratio too low. I compromised on the GIF format, but I am +not sure how long 8 bits per pixel will be enough." + +During his first spell of maintainership between 1989 and 1994, Eric +S. Raymond (aka "ESR") ported the code to Unix, wrote the high-level +DGIfSlurp()/EGifSpew() interface, rationalized the internal data +structures, and did a lot of general cleanup and refactoring to +improve the code quality. + +Between 1994 and 2012 Toshio Kuratomi fixed various tool bugs, +build-recipe problems and rare segfaults. He partially untangled the +somewhat misdesigned extension-block handling in earlier versions. +The core code was very stable during this period. + +During his second spell of maintainership, ESR fixed the +extension API, made the library re-entrant and thread-safe, wrote a +regression-test suite, greatly improved the documentation, and +discarded a lot of obsolete code. + + +The GIF descriptor + +When a GIF file is opened, a GIF file descriptor is created which +is a pointer to GifFileType structure as follows: + + +typedef struct GifFileType { + GifWord SWidth, SHeight; /* Size of virtual canvas */ + GifWord SColorResolution; /* How many colors can we generate? */ + GifWord SBackGroundColor; /* Background color for virtual canvas */ + GifByteType AspectByte; /* Used to compute pixel aspect ratio */ + ColorMapObject *SColorMap; /* Global colormap, NULL if nonexistent. */ + int ImageCount; /* Number of current image (both APIs) */ + GifImageDesc Image; /* Current image (low-level API) */ + SavedImage *SavedImages; /* Image sequence (high-level API) */ + int ExtensionBlockCount; /* Count extensions past last image */ + ExtensionBlock *ExtensionBlocks; /* Extensions past last image */ + int Error; /* Last error condition reported */ + void *UserData; /* hook to attach user data (TVT) */ + void *Private; /* Don't mess with this! */ +} GifFileType; + + +This structure was copied from gif_lib.h - the header file for the GIF +library. Any application program that uses the libgif.a library should +include it. Members beginning with S refer to the GIF screen; others hold +properties of the current image (a GIF file may have more than one image) +or point to allocated store used by various routines. + +The user almost never writes into this structure (exception: it +may occasionally be useful to alter things in the SavedImages array and +Trailing member), but can read any of these items at any time it is +valid (Image information is invalid until the first image has been read; +read; SavedImages information is valid only after a DGifSlurp() call). + +As the library needs to keep its own internal data, a Private pointer +to hidden data is included. Applications should ignore this. + +The library allocates its own memory dynamically, on opening of files, +and releases that once closed. The user is never required to allocate +any memory for any of the functions of this library, and is almost never +required to free them directly. The "almost" in the latter clause is because +one manual free() call may be required on a failed file close; see the +documentation of DGifClose() and EGifClose() for details. + +Here is a module summary: + + + +egif_lib.c + +Encoding routines, all prefixed with E. + + + + +dgif_lib.c + +Decoding routines, all prefixed with D. + + + + +gifalloc.c + +Routines for colormap handling and GIF record allocation. + + + + +gif_font.c + +The 8x8 font table for the GIF utility font. + + + + +The library includes a sixth file of hash-function code which is accessed +internally only. + +Most of the routines return GIF_ERROR (see gif_lib.h) if something +went wrong, GIF_OK otherwise. After an error return, all routines that +take a pointer-to-GifFileType argument set the Error member with a code that +can be interpreted into an expolanatory string with the function +GifErrorString() in gif_err.c. + + +Decoding (dgif_lib.c) + +The following functions are used to set up input from a GIF: + + +GifFileType *DGifOpenFileName(char *GifFileName, int *ErrorCode) + + +Open a new GIF file (in binary mode, if under Windows) using the +given GifFileName, and read its Screen information. + +If any error occurs, NULL is returned and ErrorCode is set (if +non-NULL). + + +GifFileType *DGifOpenFileHandle(int FileHandle, int *ErrorCode) + + +Open a new GIF file using the given FileHandle, and read its Screen +information. + +If any error occurs, NULL is returned and ErrorCode is set (if +non-NULL). + +Once you have acquired a handle on a GIF, the high-level +function + + +int DGifSlurp(GifFileType) + + +reads the rest of a complete (possibly multi-image) GIF file from the +indicated file handle into in-core allocated structures. It returns +GIF_OK on success, GIF_ERROR on failure; on failure, the Error member +will be set. + +Once you have done this, all image, raster, and extension-block +data in the GIF is accessable in the SavedImages member (see the +structures in gif_lib.h). When you have modified the image to taste, +write it out with EGifSpew(). + +One detail that may not be clear from just looking at the +structures is how extension blocks and sub-blocks are stored. Each +ExtensionBlock structure represents an extension data block. Those +with a zero function code represent continuation data blocks attached +to previous blocks with nonzero function codes. + +You can read from a GIF file through a function hook. Initialize +with + + +GifFileType *DGifOpen(void *userPtr, InputFunc readFunc, int *ErrorCode) + + +and see the library header file for the type of InputFunc. + +There is also a set of deprecated functions for sequential I/O, +described in a later section. + +Encoding (egif_lib.c) + +The high-level function + + +int EGifSpew(GifFileType *GifFile) + + +writes a complete (possibly multi-image) GIF file to the indicated file +handle from in-core allocated structures created by a previous DGifSlurp() +or equivalent operations. Its argument is a GIF file descriptor, which +imnplicitly points to storage previously allocated by DGifSlurp(). + +The file is written with a GIF87 stamp unless it contains one of the four +special extension blocks defined in GIF89, in which case it is written +with a GIF89 stamp. + +EGifSpew() finishes by closing the GIF (writing a termination +record to it) and deallocating the associated storage. + +You can write to a GIF file through a function hook. Initialize +with + + +GifFileType *EGifOpen(void *userPtr, OutputFunc writeFunc, int *ErrorCode) + + +and see the library header file for the type of OutputFunc. + +There is also a set of deprecated functions for sequential I/O, +described in a later section. + +Color map handling and allocation routines + + +ColorMapObject *GifMakeMapObject(int ColorCount, GifColorType *ColorMap) + + +Allocate storage for a color map object with the given number of +RGB triplet slots. If the second argument is non-NULL, initialize +the color table portion of the new map from it.

If the result +won't fit into 256 colors, NULL is returned, the allocated union +otherwise. ColorIn1 is copied as it to ColorUnion, while colors from +ColorIn2 are copied iff they didn't exist before. ColorTransIn2 maps +the old ColorIn2 into ColorUnion color map table. + + +SavedImage *GifAttachImage(GifFileType *GifFile) + + +Add an image block to the SavedImages array. The image block is +initially zeroed out. This image block will be seen by any following +EGifSpew() calls. + + +Graphics control extension handling + +GIF89 added a graphics control extension block, but versions +of GIFLIB before 5.0 weren't much help in reading or modifying them. +This lack has been remedied with the following structure and functions: + + +typedef struct GraphicsControlBlock { + int DisposalMode; +#define DISPOSAL_UNSPECIFIED 0 /* No disposal specified. */ +#define DISPOSE_DO_NOT 1 /* Leave image in place */ +#define DISPOSE_BACKGROUND 2 /* Set area too background color */ +#define DISPOSE_PREVIOUS 3 /* Restore to previous content */ + bool UserInputFlag; /* User confirmation required before disposal */ + int DelayTime; /* pre-display delay in 0.01sec units */ + int TransparentColor; /* Palette index for transparency, -1 if none */ +#define NO_TRANSPARENT_COLOR -1 +} GraphicsControlBlock; + +int DGifSavedExtensionToGCB(GifFileType *GifFile, + int ImageIndex, + GraphicsControlBlock *GCB); +int EGifGCBToSavedExtension(const GraphicsControlBlock *GCB, + GifFileType *GifFile, + int ImageIndex); + + +With these functions you can extract the data from a graphics +control extension associated with a saved image into a +GraphicsControlBlock, modify it, and write it back out. Note that if +the specified saved image doesn't have a graphics control extension, +DGifSavedExtensionToGCB() will fill the GCB with default values and +return GIF_ERROR (which can be ignored); EGifGCBToSavedExtension() +will create a new leading extension block. + + +Error Handling (gif_err.c) + + +int GifErrorString(int ErrCode) + + +Returns a sting describing the specified GIFLIB error code. +Return NULL if the argument is not a valid error code. + + +The GIF Utility Font + +The 8x8 utility font used in gifecho and gifcolor lives in the library +module gif_font.c, in a table called GifAsciiTable.

GifFile should not be used +after this routine has been called. + +Returns GIF_ERROR if something went wrong, GIF_OK otherwise.When +GIF_ERROR is returned, the GifFile structure is not freed so that the +diagnostic error code will remain accessible in GifFile->Error. + + + + +Forward and Backward Compatibility + +Except for some details of extension-block handling and the addition +of read/write function hooks, the DGifSlurp()/EGifSpew() interface has +been stable since 1990. It is expected to remain so. + +However, the signatures of the file-opener functions were changed in 5.0 +in order to make the library fully reentrant and thread-safe - earlier library +versions did not feature the final pointer-to-error-code argument in +DGifOpen() and friends. For the same reason, the static storage queried by +GifLastError() in older versions is gone, and that function abolished. + +The library header contains some version #defines you can use if you +need to condition your code so it can compile with different library +versions + +Versions up to 4.1.6 defined a GIF_LIB_VERSION macro that was +string-valued with a tricky format to parse. This macro has been +retired. + +Versions after 4.1.6 define integer-valued GIFLIB_MAJOR, GIFLIB_MINOR, +and GIFLIB_RELEASE macros for the three components of the version. See the +NEWS file in the GIFLIB distribution to track API changes. + +The following functions are entirely new: + + +New functions DGifSavedExtensionToGCB() and +EGifGCBToSavedExtension() make it easy to read and edit GIF89 graphics +control blocks in saved images. + + +A few changes in behavior were introduced in 5.0: + +General behavior + + +The library is now fully re-entrant and +thread-safe. + + + All functions exported by this library now have DGif, +EGif, or Gif as a name prefix. +The default GIF version to write is now computed at +write time from the types of an image's extension blocks. (Formerly +EGifSpew() behaved this way, but the sequential-writing code didn't.) +The result of this computation is available through the new function +EGifGetGifVersion(). + + + +In documented functions: + + +GIF file openers - DGifOpenFileName(), +DGifOpenFileHandle(), DGifOpen(), EGifOpenFileName(), +EGifOpenFileHandle(), and EGifOpen() - all now take a final integer +address argument. If non-null, this is used to pass back an error +code when the function returns NULL. +EGifSlurp() and EGifSpew() read and write +extension blocks trailing after the last image, handle interlaced +images properly. +EGifPutExtensionFirst() has been replaced by +EGifPutExtensionLeader(); the difference is the new function doesn't +take an optional block, it just writes a block +leader. +EGifPutExtensionNext() has been replaced by +EGifPutExtensionBlock(); the difference is that the new function does +not take and then discard a function code argument. +EGifPutExtensionLast() has been replaced by +EGifPutExtensionTrailer(); all it does is write the terminator +block. Split your old EGifPutExtensionLast() calls into +EGifPutExtensionBlock() followed by +EGifPutExtensionTrailer(). + + + +In undocumented functions: + + +Some undocumented functions have been renamed. +AddExtensionBlock() is now GifAddExtensionBlock(), and takes an additional +function code argument. ApplyTranslation() is now GifApplyTranslation(); +FreeExtension() has become GifFreeExtensions() and takes a different argument +type; MakeSavedImage() is now GifMakeSavedImage(), FreeSavedImages() is +now GifFreeSavedImages(), and BitSize() is now GifBitSize(). +Three documented functions - MakeMapObject(), +FreeMapObject(), and UnionColorMap() - have been renamed to +GifMakeMapObject(), GifFreeMapObject(), and GifUnionColorMap() +respectively. + + + +Error handling: + + +Library error handling no longer uses a static cell to +store the last error code registered; that made the library +thread-unsafe. +For functions other than GIF file openers, the Error +code is now put in an Error member of the GifFileType +structure. +The GifError() amd +GifLastError() functions that referenced that static cell are gone, +and the GifErrorString() function introduced in the 4.2 release now +takes an explicit error code argument. + + + +Skeletons of GIF filters + +If you are developing on a virtual-memory OS such as most flavors of +UNIX, or are otherwise sure of having enough memory to keep all of GIFs you +need to operate in core, writing a filter is trivial. See the file +gifsponge.c in util. + +A sequential filter skeleton will usually look like the example file +giffilter.c in util. + +Please look at the utilities in the util directory for more ideas once +you feel comfortable with these skeletons. Also try to follow the coding +standards of this package if you want the maintainer to officially add your new +utility to it. + + +Unimplemented features + +Some features of the original GIF specification have not stood the +test of time. This library mostly ignores them, but they are described +here for completeness. + +The GIF standard fails to be explicit about a small but crucial detail: +the unsigned two-byte integer fields in it are little-endian. + +The GIF format seems to have been designed with the idea that viewers +would render multiple images in a GIF on a common canvas, giving an effect like +a picture wall. The 'logical screen descriptor block' (LSDB), 6 bytes right +after the 6-byte GIF stamp and version header at the beginning of a +GIF file, includes both two-byte canvas width and canvas height +fields and a canvas background color. Each image, besides height and +width, also has 'left' and 'top' cordinates specifying where it is to +be placed on the canvas. + +GIFLIB can read and set these fields; the gifpos and giftool +utilities will enable you to script such changes. But browsers and +modern image viewers ignore them. Nowadays multiple-image GIFs are +generally used either as animations in which each sub-image is a frame +or as image libraries, with the GIF client handling compositing into +some canvas about which the GIF format holds no information. + +Another feature of the LSDB that is generally ignored is the +pixel aspect ratio byte. Until 5.0, GIFLIB ignored this flag on input +and zeroed it on output; now it is read and preserved if present. The +GIF standard doesn't give a rationale for it, but it seems likely that +the designers intended it for representing image captures from the +analog television of the day, which had rectangular pixel-equivalents. + +Yet another ignored feature of both the LSDB and sub-images is +the sort flag, which is supposed to signal whether the colors in the +associated color map are sorted by decreasing importance in case the +display device can only render a limited number of them. This feature +reflected the high cost of dual-port memory at the time the GIF +specification was written in the late 1980s. That kind of limit +disappeared in the mid-1990s. Until 5.0, GIFLIB ignored this flag on +input and zeroed it on output; now it is read and preserved if +present. + +Finally, the plaintext extension block. This is an extension block +that contains instructions for overlaying text captions on a following image. +GIFLIB treats these blocks as raw data, not attempting to parse out the +location and text data. + +

giftext

- -A program to dump (text only) general information about GIF file.

- -

Usage:

- -
-giftext [-q] [-c] [-e] [-z] [-p] [-r] [-h] gif-file
-
- -If no gif-file is given, GifText will try to read a GIF file from stdin.

- -As giftext can generate huge amounts of data, ^C will kill it, but 'q' will -stop only the printing (of one of -e, -z, -p), while file integrity will still -be checked.

- -

Memory required:

- -Line. - -

Options:

- -
-
[-q] -
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout - of running scan lines. Use -q- to invert.

- -

[-c] -
Dumps the color maps.

- -

[-e] -
Dumps encoded bytes - the pixels after compressed using LZ - algorithm and chained to form bytes. This is the form the data is saved - in the GIF file. Dumps in hex - 2 digit per byte.

- -

[-z] -
Dumps the LZ codes of the image. Dumps in hex - 3 digits per - code (as we are limited to 12 bits).

- -

[-p] -
Dumps the pixels of the image. Dumps in hex - 2 digit per - pixel (<=byte).

- -

[-r] -
Dumps raw pixels as one byte per pixel. This option inhibits all - other options and only the pixels are dumped. This option may be used to - convert GIF files into raw data. Note: the color map can be extracted by - gifclrmp utility. If more than one image is included in the file, all - images will be dumped in order.

- -

[-h] -
Print one line of command line help, similar to Usage above.

-

Specification Syntax

- -Here is a syntax summary in informal BNF. The token `NL' represents a -required newline.

- -

-<gif-spec> ::= <header-block> <image-block>...
-
-<header-block> ::= <header-declaration>...
-
-<header-declaration ::=
-		| screen width <digits> NL
-		| screen height <digits> NL
-		| screen colors <digits> NL
-		| screen background <digits> NL
-		| screen map <color-table> NL
-
-<color-table> ::= <color-declaration>... end NL
-
-<color-declaration> ::= rgb <digits> <digits> <digits> is <key> NL

-
-<image-declarations> ::= image top <digits> NL
-			| image left <digits> NL
-			| image interlaced NL
-			| image map <color-table> NL
-			| image bits <digits> by <digits> NL <raster-block>
-
-<extension> := <comment> NL <extension-block> NL end NL
-		| <plaintext> NL <extension-block> NL end NL
-		| extension <hex-digits> NL <extension-block> NL end NL
-
- -If the semantics of the `screen height', `screen width', `screen background', -`image top', `image left' declarations aren't obvious to you, what are you -doing with this software?

- -A color table declares color indices (in ascending order from 0) and -assiciates them with key characters. These characters can later be used in -raster blocks. As these must be printable and non-whitespace, you can only -specify 94 colors per icon. Life is like that sometimes.

- -A raster block is just a block of key characters. It should be sized correctly -for the `image bits' declaration that leads it.

- -The `comment' or `plaintext' keywords lead defined GIF89 extension -record data (the other two GIF89 types, graphics control and application -block, are not yet supported). You can also say `extension' followed -by a hexadecimal record type. All of these extension declarations -must be followed by an extension block, which is terminated by the -keyword `end' on its own line.

- -An extension block is a series of text lines, each interpreted as a string of -bytes to fill an argument block (the terminating newline is stripped). Text -may include standard C-style octal and hex escapes preceded by a backslash.

- -All tokens are interpreted as decimal numerals; -tokens are interpreted as two hex digits (a byte). All coordinates are -zero-origin with the top left corner (0,0). Range checking is weak and -signedness checking nonexistent; caveat hacker!

- -In general, the amount of whitespace and order of declarations within a -header or image block is not significant, except that a raster picture -must immediately follow its `image bits' bits declaration.

- -The `include' declaration includes a named GIF as the next image. The global -color maps of included GIFs are merged with the base table defined by any -`screen color' declaration. All images of an included multi-image GIF will -be included in order.

- -Comments may be preceded with `#' and will be ignored.

- -

Memory required:

- -For the compilation mode, proportional to the size of the input file. For -dumping, proportional to the line size of the widest GIF.

- -

Options:

- -
-
[-q] -
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout - of running scan lines. Use -q- to invert.

- -

[-d] -
Dump the input GIF file(s) into the text form described above.

- -

[-t] -
Specify name characters to use when dumping raster blocks. Only - valid with -d option.

- -

[-h] -
Print one line of command line help, similar to Usage above.

-

- -

Bugs:

- -Because there are only 94 characters unambiguously usable for raster blocks, -an attempt to dump a GIF with a larger color map will fail.

- -Error checking is rudimentary.

- -

Example:

- -A sample icon file called `sample.ico' is included in the pic directory.

Introduction to GIFLIB

- -GIFLIB is a package of portable tools and library routines for working -with GIF images. You can find the latest version at the GIFLIB home -page http://www.ccil.org/~esr/giflib.

- -The Graphics Interchange Format(c) specification is the copyrighted -property of CompuServe Incorporated. GIF(sm) is a service mark -property of CompuServe Incorporated. As this package existed before -UniSys's lawyeritis attack of New Years' Day 1995, it is grandfathered -in under their license terms and you do not have to pay fees -for using it.

- -This package has been released under an X Consortium-life freeware -license. Use and copy as you see fit. If you make useful changes, -add new tools, or find and fix bugs, please send your mods to the -maintainers for general distribution.

- -The util directory includes programs to clip, rotate, scale, and -position GIF images. It includes an X11 viewer, code to dump GIFs to -an Epson-compatible printer in graphics mode, and many conversion -utilities. These are no replacement for an interactive graphics -editor, but they can be very useful for scripted image generation or -transformation.

- -The library includes program-callable entry points for reading and writing -GIF files, an 8x8 utility font for embedding text in GIFs, and an error -handler. GIF manipulation can be done at a relatively low level by -sequential I/O (which automatically does/undoes image compression) or at -a higher level by slurping an entire GIF into allocated core.

- -This library speaks both GIF87a and GIF89. The differences between -GIF87 and GIF89 are minor: in the latter, the interpretation of some -extension block types is defined. The library never needs to actually -interpret these, but giftext notices them.

- -

Utilities

- -Here is a summary of the utilities in this package. If you're looking -at this page through a web browser, each utility name should be a -hotlink to HTML documentation.

- -

text2gif -
generate GIF images out of regular text in 8x8 font -
gifinto -

C Code Templates

- -
-
giffiltr -
template code for filtering a GIF sequentially -
gifspnge -
template code for filtering a GIF with in-core operations -
- -Under MS-DOS, most filters will print the current input scan line number -(counting up) whenever they read image input, and will print output image line -number (counting down) when they dump output. Utilities that only read or -write always print in increasing order. Utilities (like GifPos that only -change positions) that copy the image as a block of compressed data will print -nothing --- they cannot identify a scan line number, and are enough faster that -the feedback to the user doesn't seem necessary.

- -Some of the utilities require memory on the order of the whole screen, while -others read one scan line at a time. Each utility HTML file has entry called -Memory Usage which will be one of:

- -

-
Line
memory required is on the order of one scan line -
Image
proportional to the size of the biggest image in GIF file -
Screen
proportional to GIF screen size -
- -In all cases a byte is allocated per pixel, so an image of 320 by 200 pixels -will requires approximately 64k bytes of main memory.

- -

Library Functions

- -The library contains two groups of C functions. One group does sequential -I/O on the stream-oriented GIF format. The other supports grabbing an -entire GIF into allocated core, operating on it in core, and then writing -the modified in-core GIF out to disk.

- -Unless you are on a 286 or some other very memory-limited machine -running under DOS, you probably want to use the second group.

- -Detailed documentation on the library entry points is in gif_lib.html. Library error codes are -described in liberror.html

- -

The GIF Standard

- -The doc subdurector includes flat-ASCII descriptions of GIF89 format and Lempel-Ziv -Compression.

- -

History

- -This package was originally written by Gershon Elber -in 1990 on an IBM PC under MS-DOS using Borland Turbo C. He made it portable -to several UNIX environments.

- -The 2.1 version featured substantial changes and additions by Eric -S. Raymond . These included the -DGifSlurp/EGifSpew function pair for enabling non-sequential -operations on GIF images and the tools icon2gif, gifovly, gifburst, and -gifcompose.

- -The 2.4 version converted all the docs from an idiosyncratic -plain-text formal to to HTML.

- -

Package Status

- -GIFLIB's current maintainer is Eric S. Raymond. You can find his home -page at http://www.ccil.org/esr.

- -GIFLIB is not under active development, but bug fixes are being accepted.

If you're looking +at this page through a web browser, each utility name should be a +hotlink to HTML documentation. + +Most utilities have a -v (verbose) option that will cause them to print +the current input scan line number (counting up) whenever they read +image input, and will print output image line number (counting down) +when they dump output. Utilities that only read or write always print +in increasing order. + + + +Conversion Utilities + + + +gif2rgb + +convert images saved as GIF to 24-bit RGB image(s) or vice-versa + + + +gif2raw + +convert GIF files into raw 8-bit image data or vice-versa + + + + + +Test Pattern Generators + + + +gifbg + +generate a single-color test pattern GIF + + + +gifcolor + +generate color test patterns + + + +gifwedge + +create a test GIF image resembling a color monitor test pattern + + + + + +Image Manipulation Components + + + +gifclrmp + +modify GIF image colormaps + + + +giffix + +clumsily attempts to fix truncated GIF images + + + + + +Report Generators + + + +giftext + +print (text only) general information about a GIF + + + +gifhisto + +generate color-frequency histogram from a GIF + + + + + +GIF Composition Tools + + + +gifbuild + +converter/deconverter to/from an editable text format + + + +gifecho + +generate GIF images out of regular text in 8x8 font + + + +gifinto + +end-of-pipe fitting for GIF-processing pipelines + + + +giftool + +GIF transformation tool + + + + + + +Library Functions + +The library contains two groups of C functions. One group does +sequential I/O on the stream-oriented GIF format. The other supports +grabbing an entire GIF into allocated core, operating on it in core, +and then writing the modified in-core GIF out to disk. + +Unless you are on extremely memory-limited machine, you probably want +to use the second group. + +Detailed documentation on the library entry points is in gif_lib.html. + + +The GIF Standard + +The doc subdirectory includes flat-ASCII descriptions of GIF89 format and Lempel-Ziv Compression. For historical +completeness, we also include a copy of the GIF87 standard. + +You can also read a +detailed narrative description of how GIFs are laid out. It +clarifies some points on which the standard is obscure. + + +Package Status + +GIFLIB's current maintainer is Eric S. Raymond.

GIFLIB error codes

- -Errors as reported from the GIF_LIB library are divided to two major -categoriess: the encoder (errors prefixed by E_GIF_ERR), and the -decoder (errors prefixed by D_GIF_ERR). This document explains them -briefly:

- -

Encoding errors:

- -
-
E_GIF_ERR_OpenFailed
- Message printed using PrintGifError: "Failed to open given file" - IO error result when attempt to open the given GIF file.

- -

E_GIF_ERR_WriteFailed
- Message printed using PrintGifError: "Failed to Write to given file" - IO error result when attempt to write to the given GIF file.

- -

E_GIF_ERR_HasScrnDscr
- Message printed using PrintGifError: "Screen Descriptor already been set" - Attempt to write second screen descriptor to same GIF file. GIF file should - have exactly one screen descriptor which should be set directly after the - file is opened.

- -

E_GIF_ERR_HasImagDscr
- Message printed using PrintGifError: "Image Descriptor is still active" - Image descriptor should be sent before and image dump, and no second - image descriptor should be sent before current image dump ended. This error - occurred probably because current image was not complete.

- -

E_GIF_ERR_NoColorMap
- Message printed using PrintGifError: "Neither Global Nor Local color map" - An image must have either global (screen) or local (image) color map. - Neither were given in this case.

- -

E_GIF_ERR_DataTooBig
- Message printed using PrintGifError: "#Pixels bigger than Width * Height" - The number of pixels dumped for this image is bigger than specified by - image Height times image Width.

- -

E_GIF_ERR_NotEnoughMem
- Message printed using PrintGifError: "Fail to allocate required memory" - Once an attemp is made to open GIF file, special structures are allocated - to hold internal data for it. If allocation fails this error is returned.

- -

E_GIF_ERR_DiskIsFull
- Message printed using PrintGifError: "Write failed (disk full?)" - Writing encoded data failed.

- -

E_GIF_ERR_CloseFailed
- Message printed using PrintGifError: "Failed to close given file" - Closing file failed.

- -

E_GIF_ERR_NotWriteable
- Message printed using PrintGifError: "Given file was not opened for write" - GIF files can be opened both for read (DGIF part of library) and write - (EGIF part of library). This error occurs when a file is opened for read - (using DGIF) is given to one of the encoding (EGIF) routines.

-

- -

Encoding errors:

- -
-
D_GIF_ERR_OpenFailed
- Message printed using PrintGifError: "Failed to open given file" - IO error result when attempt to open the given GIF file.

- -

D_GIF_ERR_ReadFailed
- Message printed using PrintGifError: "Failed to Read from given file" - IO error result when attempt to write to the given GIF file.

- -

D_GIF_ERR_Notgif-file$
- Message printed using PrintGifError: "Given file is NOT GIF file" - GIF files should have special stamp identifies them as such, If that stamp - is not found, this error is issued.

- -

D_GIF_ERR_NoScrnDscr
- Message printed using PrintGifError: "No Screen Descriptor detected" - Each GIF file should have screen descriptor in its header. This error will - be generated if no such descriptor was found.

- -

D_GIF_ERR_NoImagDscr
- Message printed using PrintGifError: "No Image Descriptor detected" - Each image should have image descriptor in its header. This error will - be generated if no such descriptor was found.

- -

D_GIF_ERR_NoColorMap
- Message printed using PrintGifError: "Neither Global Nor Local color map" - An image must have either global (screen) or local (image) color map. - Neither were given in this case.

- -

D_GIF_ERR_WrongRecord
- Message printed using PrintGifError: "Wrong record type detected" - Each record in GIF file has special identifier, in its header. If the - record has wrong identifier, this error is generated.

- -

D_GIF_ERR_DataTooBig
- Message printed using PrintGifError: "#Pixels bigger than Width * Height" - The number of pixels dumped for this image is bigger than specified by - image Height times image Width.

- -

D_GIF_ERR_NotEnoughMem
- Message printed using PrintGifError: "Fail to allocate required memory" - Once an attemp is made to open GIF file, special structures are allocated - to hold internal data for it. If allocation fails this error is returned.

- -

D_GIF_ERR_CloseFailed
- Message printed using PrintGifError: "Failed to close given file" - Closing file failed.

- -

D_GIF_ERR_NotReadable
- Message printed using PrintGifError: "Given file was not opened for read" - GIF files can be opened both for read (DGIF part of library) and write - (EGIF part of library). This error occurs when a file is opened for write - (using EGIF) is given to one of the decoding (DGIF) routines.

- -

D_GIF_ERR_ImageDefect
- Message printed using PrintGifError: "Image is defective, decoding aborted" - This error is generated, once the decoding failed - probably image is - defect.

- -

D_GIF_ERR_EOFTooSoon
- Message printed using PrintGifError: "Image EOF detected, before image complete" - This error is generated once EOF code is detected in encoded image before - all the pixels (Width * Height) has be decoded.

raw2gif

- -A program to convert RAW image data into GIF files. Only one image can be -handled. The RAW image file is assumed to hold one pixel color in one byte, -and therefore the file size must be Width times Height as specified by the --s option below.

- -

Usage:

- -
-raw2gif [-q] -s Width Height [-p ColorMapFile] [-h] RawFile
-
- -If no RawFile is given, Raw2Gif will try to read RAW data from stdin. -The generated GIF File is dumped to stdout.

- -

Memory required:

- -Line. - -

Options:

- -
-
[-q] -
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout - of running scan lines. Use -q- to invert.

- -

-s Width Height -
the dimensions of the image MUST be specified in the - command line. The RAW image file size must be exactly Width times Height - bytes (each byte is one pixel color).

- -

[-p ColorMapFile] -
Color map to load for given RAW image. This file has - 4 integers in line (ColorIndex Red Green Blue), and the ColorIndex is - in order starting from 1. See GifClrMp, which can also use/create these - bitmap files. If no color map is specified, uses the EGA 16 color pallete - as default color map.

- -

[-h] -
Print one line of command line help, similar to Usage above.

rgb2gif

- -A program to convert 24 bit images to a GIF image using color quantization.

- - -

Usage:

- -
-rgb2gif [-q] [-c #Colors] [-1] -s Width Height [-h] RGBFile
-
- -If no RGBFile is given, RGB2Gif will try to read a GIF file from stdin.

- -

Memory required:

- -Screen. - -

Options:

- -
-
[-q] -
Quiet mode. Defaulte off on MSDOS, on under UNIX. Controls printout - of running scan lines. Use -q- to invert.

- -

[-c #Colors] -
Specifies number of colors to use, in bits per pixels, so - '-c 8' specifies actually 256 colors (maximum and default).

- -

[-1] -
Only one file in the format of RGBRGB... triplets (Each of R, G, B - is a byte) is read from input. This file size is 3 * Width * Height (see - '-s' below. If stdin is used for input, this option is implicitly applied. - The default (if not '-1') is 3 files with the names RGBFile.R, RGBFile.G, - RGBFile.B, each of which is Width * Height bytes.

- -

[-s Width Height] -
Specifies the size of the image to read.

- -

[-h] -
Print one line of command line help, similar to Usage above.

rle2gif

- -A program to convert images saved as RLE (Utah raster toolkit) to GIF -format.

- -

Usage:

- -
-rle2Gif [-q] [-c #Colors] [-h] RleFile
-
- -If no RleFile is given, Rle2Gif will try to read an Rle file from stdin.

- -

Memory required:

- -Screen. - -

Options:

- -
-
[-q] -
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout - of running scan lines. Use -q- to invert.

- -

[-c #Colors] -
Select size of color map in the output Gif file. #Colors - should be given as the based 2 log of number of colors. Default is 8 - which is 256 colors, and which is also the maximum. - -
[-h] -
Print one line of command line help, similar to Usage above..

-

- -

Notes:

- -As the RLE format allows full 24 bits per pixel (8 per primary color) -Colors must be quantized to the number of colors as set by the [-c] -option, above. This process is quite slow. See the quantize.c file -in the lib directory for the code for this quantization algorithm -(median cut).

What's In A GIF

(animation and transparency)
+ +
+ + +

In addition to being able to store simple image data, +GIF files (specifically GIF89a files) allow for some special features. Tricks +such as transparency and animation can be accomplished with the +help of the Graphics Control Extension block. Here's a sample of what this +block looks like:

+ +

+ +

I'll show you how to manipulate the bytes in this block to achieve +special effects.

+ +

Animation

+ +

Cartoons are created by animators who draw a sequence of pictures, +each slightly different from the one before, which, when rapidly shown +one after the other, give the illusion of motion. Animation in GIF +images is achieved in much the same way. Multiple images may be stored +in the same file and you can tell the computer how much time to wait +before showing the next image. Let's walk though the parts that make +up this simple traffic light animation. +

+ +

+

+ + 47 + 49 + 46 + 38 + 39 + 61 + 0B + 00 + 1D + 00 + A2 + 05 + 00 + FF + 00 + 00 + 00 + FF + 00 + FF + FF + 00 + 8E + 8E + 8E + 00 + 00 + 00 + FF + FF + FF + 00 + 00 + 00 + 00 + 00 + 00 + 21 + FF + 0B + 4E + 45 + 54 + 53 + 43 + 41 + 50 + 45 + 32 + 2E + 30 + 03 + 01 + 00 + 00 + 00 + 21 + F9 + 04 + 04 + 64 + 00 + 00 + 00 + 2C + 00 + 00 + 00 + 00 + 0B + 00 + 1D + 00 + 00 + 03 + 30 + 48 + BA + DC + DE + 23 + BE + 48 + 21 + AD + EB + 62 + A5 + 25 + D3 + 93 + F7 + 8C + E4 + 27 + 9A + 1B + D7 + A1 + 17 + 9B + 1E + A0 + F3 + 96 + 34 + 13 + DC + CF + AD + 37 + 7A + 6F + F7 + B8 + 05 + 30 + 28 + F4 + 39 + 76 + B5 + 64 + 02 + 00 + 21 + F9 + 04 + 04 + 32 + 00 + 00 + 00 + 2C + 02 + 00 + 0B + 00 + 07 + 00 + 10 + 00 + 00 + 03 + 19 + 78 + 27 + AC + CB + 0D + CA + 49 + E1 + B3 + 0A + BB + CD + F7 + F8 + CE + 27 + 1E + 62 + 69 + 9E + A3 + 19 + 82 + 47 + 02 + 00 + 21 + F9 + 04 + 04 + 64 + 00 + 00 + 00 + 2C + 02 + 00 + 02 + 00 + 07 + 00 + 10 + 00 + 00 + 03 + 19 + 78 + 07 + AC + CB + 0D + CA + 49 + E1 + B3 + 0A + BB + CD + F7 + F8 + CE + 27 + 1E + 62 + 69 + 9E + A3 + 19 + 82 + 45 + 02 + 00 + 3B +

+ +

This file is similar to the ones we've previously encountered. The +bytes start out with the GIF header. Next we have a logical +screen descriptor which tells us that our image is 11px by 29 px +and will have a global color table with 8 colors in it (of which we +only really need 5). Immediately after, follows the global color table +which tells us what those colors are (0=red, 1=green, 2=yellow, +3=light grey, 4=black, 5=white, 6=black [not used], 7=black [not used] +).

+ +

Next we encounter an application +extension block. This is this block that causes our animation to +repeat rather than play once and stop. The first three bytes tell us +we are looking at (1) an extension block (2) of type +"application" which is followed by (3) 11 bytes of fixed +length data. These 11 bytes contain the ASCII character codes for +"NETSCAPE2.0". Then begins the actual "application +data" which is contained in sub-blocks. There are two values that +are stored in these sub-blocks. The first value is always the byte +01. Then we have a value in the unsigned +(lo-hi byte) format that says how many times the animation should +repeat. You can see that our sample image has a value of 0; this means +the animation should loop forever. These three bytes are preceded by +the 03 that lets the decoder know that three +bytes of data follow, and they are terminated by 00, the block terminator.

+ +

This very basic animation is essentially made up of three different +"scenes". The first is the one with the green light lit, +the second with the yellow, and the last with the red. You should be +able to see three separate chunks of image data in the bytes +above.

+ + + + + + + + +
123
scene 1: green lightscene 2: yellow lightscene 3: red light
+ +

The first chunk begins immediately after the application extension +block. It is there we encounter our first graphic control +extension. As with all extensions, it begins with 21. Next, the type specific label for the graphic +control type of extension is F9. Next we see +the byte size of the data in the block; this should always be 04. The first of these four data blocks is a +packed field.

+ +

The packed field stores three values. The first three (highest) +bits are "reserved for future use" so those have been left +as zeros. The next three bits indicate the disposal method. The +disposal method specifies what happens to the current image +data when you move onto the next. We have three bits which means we +can represent a number between 0 and 7. Our sample animated image has +a value of 1 which tells the decoder to leave the image in place and +draw the next image on top of it. A value of 2 would have meant that +the canvas should be restored to the background color (as indicated by +the logical screen descriptor). A value of 3 is defined to mean that +the decoder should restore the canvas to its previous state before the +current image was drawn. I don't believe that this value is widely +supported but haven't had the chance to test it out. The behavior for +values 4-7 are yet to be defined. If this image were not animated, +these bits would have been set to 0 which indicates that do not wish +to specify a disposal method. The seventh bit in they byte is the +user input flag. When set to 1, that means that the decoder +will wait for some sort of "input" from the person viewing +the image before moving on to the next scene. I'm guessing it's highly +unlikeley that you will encounter any other value that 0 for this bit. +The final bit is the transparency flag. We will go into more detail +about transparency in the next +section. Since this image isn't using any transparency, we see +this bit has been left at 0.

+ +

The next two bytes are the delay time. This value is in the same +unsigned lformat as all the other integers in the file. This number +represents the number of hundredths of a second to wait before moving +on to the next scene. We see that our sample image has specified +a value of 100 (64 00) +in the first graphics control block which means we would wait 1 second +before changing our green light to yellow.

+ +

Our graphics control extension block ends with the block +terminator 00. You will notice this +type of block appearing two more times in this image, the second +instance differing only in the delay time (the yellow light only +stays up for half a second).

+ +

The next chunk is an image descriptor. The block declares that it +will be drawing an image starting at the top left corner and taking up +the whole canvas (11px x 29px). This block is followed by the image +data that contains all the codes to draw the first scene, the one with +the green light on.

+ + + + + + + + +
Green(Difference)Yellow
green light enlargeddifference between green and yellow imagesyellow light enlarged
+ +

If we compare the first and the second scene, we see they share many +of the same pixel color values. Rather than redrawing the whole canvas, +we can specify just the part that changes (that is, the smallest +rectangle that covers the part that changes). You'll see that the +image descriptor before the second block of image data specifies +that it will start at the pixel at (2, 11) and draws a box that's +7px wide by 16px tall. This is just large enough to cover the bottom two +lights. The works because we chose the "do not dispose" disposal +method for out graphics control extension block. In the same way, +the third and final image data block only renders the top two circles +to both fill in the red and cover up the yellow.

+ +

Transparency

+ +

Normally, GIF images are rectangles that cover up what ever +background may be beneath them. Transparency allows you to "see +though" the image to whatever is below. This is a very simple +trick to pull off in a GIF image. You can set up one color in your +color table that is converted to "invisible ink." Then, as +the image is drawn, whenever this special color is encountered, the +background is allowed to show through.

+ +

There are only two pieces of data we have to set to pull this +off. First we must set the Transparency Color Flag to 1. This is the +lowest bit in the packed byte of the Graphic Control Extension. This +will tell the decoder that we want our image to have a transparent +component. Secondly we must tell the decoder which color we want to +use as our invisible ink. The decoder will then all you to see thought +every pixel that contains this color. Therefore make sure it's not a +color that you are using else where in your image. The color you +choose must be in the active color table and you specify its value in +the Transparent Color Index byte by setting this value to the index of +the color in the color table.

+ +

Let's demonstrate this by revisiting the sample image we used +in Bits and Bytes. We will update this +file to make the white center part transparent. Let's start creating +the Graphic Control Extension block that will do this for us. Again we +start with the 21 F9 +04 punch. In the next byte, we need to flip +the transparent color flag to 1 (we can leave the others at zero) so +this whole byte is simply 01. The next two +bytes can be left at zero.

+ +

We must now specify which color to disappear. Recall that our +sample image had the following global color table:

+ + + + + + + +
IndexColor
0White
1Red
2Blue
3Black
+ +

We already know what we want to make all the white sections +transparent. The color white has an index of 0. Therefore we will +specify a value of 00 for the transparent +color index block. Had we wanted to make the red transparent we would +have used 01, or 02 for blue. Lastly we tack on the block +terminator of 00 and we're done. We have +created the following block:

+ +

+ 21 + F9 + 04 + 01 + 00 + 00 + 00 + 00 +

+ +

Now, all we have to do is plug this into our sample image right before the +image descriptor. I've placed our original sample image on a black background +as well as the one we just made so you can see the results. I've also included +ones where red or blue are transparent. The last three differ by only the +transparent color index byte.

+ + + + + + + + + + + + + + +
OriginalTransparent
+White (00)		Transparent
+Red (01)		Transparent
+Blue (02)
+previous sample +transparent white +transparent red +transparent blue
+ +

This concludes our description of the bits inside GIFs. If you +have not already read the documentation of +the GIFLIB API, you may wish to continue with that.

What's In A GIF

(Bits and bytes)
+ +
+ + +

The authority on the content of GIFs is the GIF89a specification. Originally developed at +CompuServe in the late 1980s, it is now a W3C standard.

+ +

A GIF file is made up of a sequence of data blocks. The first two +blocks are fixed length and fixed format. Later ones are variable +length but self-describing; they consisting of a byte identifying the block +type, followed by a payload length byte, followed by payload.

+ +

The following railroad diagram shows all of the different types of +blocks and where they can be in the file. Every path following the +arrows corresponds to a valid block sequence. The large middle +secction, in particular, can be repeated any number of times.

+ +

We will learn more by walking through a sample GIF file. You can +see the sample file and its corresponding bytes below.

+ +

Note that not all possible block types are represented in this +sample file. Later we'll provide samples of missing block types where +appropriate. The different types of blocks include: header, logical screen descriptor, +global color table, graphics control +extension, image descriptor, +local color table, image data, plain text extension, application extension, comment extension, and trailer. Let's get started with the first +block!

+ +

Header Block

+ +

From the sample file: + 47 + 49 + 46 + 38 + 39 + 61 +

+ +

All GIF files must start with a header block. The header takes up +the first six bytes of the file. These bytes should all correspond to +ASCII character codes. The first +three bytes are called the signature. These should +always be "GIF" (ie 47="G", 49="I", +46="F"). The next three specify the version +of the specification that was used to encode the image. + +

Normally the version string will be either "89a" (ie +38="8", 39="9",61="a") or "87a" (ie +38="8", 37="7",61="a"). All modern +GIF-processing software recognizes both versions, For maximum +compatibility, GIFLIB will normally write an 87a signature unless the +file contains GIF89 features.

+ +

GIF header block layout

+ +

Logical Screen Descriptor

+

From Sample File: 0A + 00 0A 00 91 00 00

+ +

The logical screen descriptor always immediately follows the +header. This block tells the decoder how much room this image will +take up. It is exactly seven bytes long. It starts with the +canvas width and canvas height. +These value can be found in the first two pairs of two bytes each. +Both are 16-bit, nonnegative integers (0-65,535).

+ +

As with all the other multi-byte values in the GIF format, the +least significant byte is stored first (little-endian format). This +means where we would read 0A 00 from the byte stream, we would normally write +it as 000A which is the same as 10. Thus the +width of our sample image is 10 pixels. As a further example 255 would +be stored as FF 00 + but 256 would be 00 01 .

+ +

The canvas width and height are usually ignored by modern viewers. +The GIF format seems to have been designed with the idea that viewers +would render multiple images in a GIF on a common canvas, giving an +effect like a picture wall. But nowadays multiple-image GIFs are +generally used either as animations in which each sub-image is a frame +or as image libraries, with the GIF client handling compositing into +some canvas about which the GIF format holds no information.Thus, the +canvas width and height are mainly fossils. GIFLIB does extract them +and allow you to set them, however.

+ +

The next byte contains four fields of packed data, the "logical +screen descriptor". To understand these, we need to expand the byte + 91 to binary as 10010001 and look at the fields inside it.

+ +

GIF logical screen descriptor block layout

+ +

The first (most-significant) bit is the global color table +flag. If it's 0, then there is no global color table. If it's +1, then a global color table will follow. In our sample image, we can +see that we will have a global color table (as will usually be the +case).

+ +

The next three bits are the color resolution. They +are only meaningful if there is a global color table, and allow you to +compute its size. If the value of this filed is N, the number of +entries in the global color table will be 2 ^ (N+1) - that is, two +raised to the power (N+1). Thus, the 001 in +the sample image represents 2 bits/pixel; 111 would represent 8 bits/pixel.

+ +

The GIF format shows its age here. A more modern design would +simply have allocated a byte or two for color table length. But GIF +was designed when memory was much more expensive than it is today, +and the designers felt strong pressure to economize on every bit. +The consequence is that color table lengths have to be an exact power +of two. Perversely, this can force a waste of memory space in images +with odd color counts.

+ +

The next single bit is the sort flag. If the +values is 1, then the colors in the global color table are sorted in +order of "decreasing importance," which typically means +"decreasing frequency" in the image. This can help the image +decoder, but is not required. In the sample file this value has been +left at 0.

+ +

The sort flag reflected the high cost of dual-port memory at the +time the GIF specification was written in the late 1980s. That kind +of limit disappeared in the mid-1990s, and modern GIF software ignores +this flag. Until version 5.0, GIFLIB ignored it on input and zeroed +it on output; 5.0 and later versions read and preserve it.

+ +

The next byte gives us the background color +index. This byte is only meaningful if the global color table +flag is 1, and if there is no global color table, this byte should be +0.. To understand it you have to remember the original "picture wall" +rendering model for GIFs in which sub-images are composited onto a +larger canvas. It represents which index in the global color table +should be used for pixels on the virtual canvas that aren't overlayed +by an image. GIFLIB supports reading and setting this byte, but modern +viewers and browsers generally have no use for it.

+ +

The last byte of the logical screen descriptor is the pixel +aspect ratio. Modern viewers don't use this. Until 5.0, +GIFLIB ignored this flag on input and zeroed it on output; now it is +read and preserved if present. The GIF standard doesn't give a +rationale for it, but it seems likely that the designers intended it +for representing image captures from the analog television of the day, +which had rectangular pixel-equivalents. The GIF specification says +that if there was a value specified in this byte, N, the actual ratio +used would be (N + 15) / 64 for all N<>0.

+ +

Global Color Table

+ +

From the sample file: + FF + FF + FF + FF + 00 + 00 + 00 + 00 + FF + 00 + 00 + 00 +

+ +

GIFs can have either a global color table or local +color tables for each sub-image. Each color table consists of a list +of RGB (Red-Green-Blue) color component intensities, three bytes for +each color, with intensities ranging from 0 (least) to 255 (most). The +color (0,0,0) is deepest black, the color (255,255,255) brightest +white. The other extreme colors are red at (255,0,0), green at +(0,255,0) and blue at (0,0,255).

+ +

As previously noted, the length of the global color table is +2^(N+1) entries where N is the value of the color depth field in the +logical screen descriptor. The table will take up 3*2^(N+1) bytes in +the stream.

+ +
+ + + + + + + + + + +

Colors		Byte

1412
2824
31648
43296
564192
6128384
7256768
+
+ +

Our sample file has a global color table size of 1. This means it +holds 2^(1+1)=2^2=4 colors. We can see that it takes up 12, (3*4), +bytes as expected. We read the bytes three at a time to get each of +the colors. The first color is #FFFFFF (white). This value is given an +index of 0. The second color is #FF0000 (red). The color with an +index value of 2 is #0000FF (blue). The last color is #000000 +(black). The index numbers will be important when we decode the actual +image data.

+ +

Note that this block is labeled as "optional." Not every +GIF has to specify a global color table. However, if the global color +table flag is set to 1 in the logical screen descriptor block, the +color table is then required to immediately follow that block. +

+ +

+ +

Graphics Control Extension

+ +

From the sample file: + 21 + F9 + 04 + 00 + 00 + 00 + 00 + 00 +

+ +

Graphic control extension blocks are used to specify transparency +settings and control animations. They are an optional GIF89 extension. +The semantics of this extension will be described in detail in a later section +(see Transparency and Animation); +for completeness we'll describe the data fields here.

+ +

The first byte is the extension introducer. All +extension blocks begin with 21. Next is the graphic control +label, F9, which is the value that +flags this as a graphic control extension. Third up is the total +block size in bytes. Next is a packed field. Bits 1-3 +are reserved for future use. Bits 4-6 indicate disposal +method. The penultimate bit is the user input +flag and the last is the transparent color +flag. The delay time value follows in the +next two bytes stored in unsigned format. After that we have the +transparent color index byte. Finally we have the +block terminator which is always 00.

+ +

+ +

Image Descriptor

+ +

From the sample file: + + 2C + 00 + 00 + 00 + 00 + 0A + 00 + 0A + 00 + 00 +

+ +

A single GIF file may contain multiple images. In the original GIF +rendering model these wwere meant to be composited onto a larger +virtual canvas. Nowadays nultiple images are normally used for animations.

+ +

Each image begins with an image descriptor block. This block is +exactly 10 bytes long.

+ +

The first byte is the image separator. Every image +descriptor begins with the value 2C. The +next 8 bytes represent the location and size of the following +image.

+ +

An image in the stream may not necessarily take up the entire +canvas size defined by the logical screen descriptor. Therefore, the +image descriptor specifies the image left position +and image top position of where the image should +begin on the canvas. Both these fields are usually ignored by modern +viewers and browsers.

+ +

Next, this block specifies the image width and +image height. Each of these values is in the +two-byte, unsigned little-endian format. Our sample image indicates +that the image starts at (0,0) and is 10 pixels wide by 10 pixels +tall. (This image does take up the whole canvas size.)

+ +

The last byte is another packed field. In our sample file this byte is 0 so +all of the sub-values will be zero. The first (most significant) bit in +the byte is the local color table flag. Setting this flag +to 1 allows you to specify that the image data that follows uses a different +color table than the global color table. (More information on the local +color table follows.)

+ +

The second bit is the interlace flag. Interlacing +changes the way images are rendered onto the screen in a way that may +reduce annoying visual flicker. The effect of interlacing on a display +is that the first pass of appears immediately, displaying the graphic +as a first as a blur and then sharpenining it up as later passes fill +in lines. That allows the human viewer to at least get an idea of +what's coming up rather than waiting for the entire image to be +painted, line by line. See an +example. To support this, the scan lines of the image need to be +stored in a different order than the normal top-down, separated into +sections that will be rendered in four separate passes.

+ +

+ +

Local Color Table

+

A local color table is organized the same as a global color table. The local +color table would always immediately follow an image descriptor but will only +be there if the local color table flag is set to 1. It is effective only for the +block of image data that immediately follows it. If no local color table +is specified, the global color table is used for the following image data.

+ +

The size of the local color table can be calculated by the value +given in the image descriptor. Just like with the global color table, +if the image descriptor specifies a size of N, the color table will +contain 2^(N+1) colors and will take up 3*2^(N+1) bytes.

+ +

Image Data

+ +

From the sample file: + 02 + 16 + 8C + 2D + 99 + 87 + 2A + 1C + DC + 33 + A0 + 02 + 75 + EC + 95 + FA + A8 + DE + 60 + 8C + 04 + 91 + 4C + 01 + 00

+ +

Finally we get to the actual image data. The image data is composed of +a series of output codes which tell the decoder which colors to emit +to the canvas. These codes are combined into the bytes that make up +the block.

+ +

There's another section on decoding these output code into an image +(see LZW Image Data). Here we'll +just see how to determine how long the block will be.

+ +

The first byte of this block is the LZW minimum code +size. This value is used to decode the compressed output +codes. (Again, see the section on LZW +compression to see how this works.) The rest of the bytes +represent data sub-blocks. Data sub-blocks are are groups of +1 - 256 bytes. The first byte in the sub-block tells you how many +bytes of actual data follow. This can be a value from 0 (00) it 255 (FF). After +you've read those bytes, the next byte you read will tell you now many +more bytes of data follow that one. You continue to read until you +reach a sub-block that says that zero bytes follow. +

+ +

You can see our sample file has a LZW minimum code size of 2. The +next byte tells us that 22 bytes of data follow it (16 hex = 22). After we've read those 22 bytes, we +see the next value is 0. This means that no bytes follow and we have +read all the data in this block.

+ +

+ +

Plain Text Extension

+

Example (not in the sample file): + + 21 + 01 + 0C + 00 + 00 + 00 + 00 + 64 + 00 + 64 + 00 + 14 + 14 + 01 + 00 + 0B + 68 + 65 + 6C + 6C + 6F + 20 + 77 + 6F + 72 + 6C + 64 + 00

+ +

The GIF89 specification allows you to specify text captions to be +overlayed on the following image. This feature never took off; +browsers and image-processing applications such as Photoshop ignore +it, and GIFLIB doesn't try to interpret it.

+ +

The block begins with an extension introducer as all +extension block types do. This value is always 21. +The next byte is the plain text label. This value of +01 is used to distinguish plain text extensions +from all other extensions. The next byte is the block size. +This tells you how many bytes there are until the actual text data begins, or +in other words, how many bytes you can now skip. The byte value will probably be +0C which means you should jump forward 12 bytes. The +text that follows is encoded in data sub-blocks +(see Image Data to see how +these sub-blocks are formed). The block ends when you reach a sub-block of +length 0.

+ +

Application Extension

+

Example (not in sample file): + 21 + FF + 0B + 4E + 45 + 54 + 53 + 43 + 41 + 50 + 45 + 32 + 2E + 30 + 03 + 01 + 05 + 00 + 00 +

+ +

The GIF89 specification allows for application-specific information +to be embedded in the GIF file itself. This capability is not much +used. About the only known public one is the Netscape 2.0 +extension (described below) which is used to loop an animated GIF +file. We'll go into more detail on looping in when we talk about animation.

+ +

The Netscape 2.0 looping block must appear immediately after the +global color table of the logical screen descriptor. It is +19 bytes long. + +

+byte  1        : 33 (hex 0x21) GIF Extension code
+byte  2        : 255 (hex 0xFF) Application Extension Label
+byte  3        : 11 (hex 0x0B) Length of Application Block
+                 (eleven bytes of data to follow)
+bytes 4 to 11  : "NETSCAPE"
+bytes 12 to 14 : "2.0"
+byte  15       : 3 (hex 0x03) Length of Data Sub-Block
+                 (three bytes of data to follow)
+byte  16       : 1 (hex 0x01)
+bytes 17 to 18 : 0 to 65535, an unsigned integer in
+                 little-endian byte format. This specifies the
+                 number of times the loop should
+                 be executed.
+byte  19       : 0 (hex 0x00) a Data Sub-Block Terminator.
+
+

+ +

As with all extensions, we start with 21 +which is the extension introducer. Next is the +extension label which for application extensions is +FF. The next value is the block +size which tells you how many bytes there are before the +actual application data begins. This byte value should be 0B which indicates 11 bytes. These 11 bytes hold +two pieces of information. First is the application +identifier which takes up the first 8 bytes. These bytes +should contain ASCII character codes that identify to which +application the extension belongs. In the case of the example above, +the application identifier is "NETSCAPE" which is +conveniently 8 characters long. The next three bytes are the +application authentication code. The spec says these +bytes can be used to "authenticate the application +identifier." With the Netscape 2.0 extension, this value is simply +a version number, "2.0", hence the extensions name. What +follows is the application data broken into data sub-blocks. As with +the other extensions, the block terminates when you read a sub-block +that has zero bytes of data.

+ +

Comment Extension

+ +

Example (not in sample file): + 21 + FE + 09 + 62 + 6C + 75 + 65 + 62 + 65 + 72 + 72 + 79 + 00

+ +

One last GIF89 extension type is the comment extension. This allows you +to embed ASCII text in a GIF file, and is sometimes used to include an +image description, image credit, or other human-readable metadata such as +the GPS location of the image capture.

+ +

It's probably no surprise by now that the first byte is the +extension introducer which is 21. The next byte is always FE which is the comment label. +Then we jump right to data sub-blocks containing ASCII character codes +for your comment. As you can see from the example we have one data +sub-block that is 9 bytes long. If you translate the character codes +you see that the comment is "blueberry." The final byte, +00, indicates a sub-block with zero bytes +that follow which let's us know we have reached the end of the block.

+ +

+ +

Trailer

+ +

From sample file: 3B

+ +

The trailer block indicates when you've reached the end of the file. +It is always a byte with a value of 3B.

+ +

Now that you know what the basic parts of a GIF file are, let's next +focus our attention on how the actual image data is stored and compressed.

What's In A GIF

(LZW image data)
+ +
+ + +

Now let's look at exactly how we go about storing an image in a GIF +file. The GIF format is a raster format, meaning it stores image data +by remembering the color of every pixel in the image. More +specifically, GIF files remember the index of the color in a color +table for each pixel. To make that clearer, let's review the +sample image we used in the first +section.

+ + + + + + +
+

Color Table

+ + + + + + +
IndexColor
0White
1Red
2Blue
3Black
+
+ +

The color table came from the global color table block. The colors +are listed in the order which they appear in the file. The first color +is given an index of zero. When we send the codes, we always start at +the top left of the image and work our way right. When we get to the +end of the line, the very next code is the one that starts the next +line. (The decoder will "wrap" the image based on the image +dimensions.) We could encode our sample image in the following +way:

+ +

1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 1, +1, 1, 1, 1, 2, 2, 2, 2, 2, 1, 1, 1, 0, 0, 0, 0, 2, 2, 2, 1, 1, 1, +0, 0, 0, 0, 2, 2, 2, ...

+ +

The above listing shows the sequence required to render the first five +lines of the image. We could continue with this method until we've +specified the color for every pixel; however, this can result in a +rather large file. Luckily for us, the GIF format allows us to take +advantage of repetition in our output and to compress our data.

+ +

Much of the following information came from John Barkaus's tutorial +LZW and GIF Explained, which seems to have fallen off the +web. I've tried to provide more detailed samples as well +as illustrations to make the process even clearer

+ +

LZW Compression

+ +

The compression method GIF use is a variant of LZW +(Lempel-Ziv-Welch) compression. To start using this method, we need a +code table. This code table will allow us to use +special codes to indicate a sequence of colors rather than just one at +a time. The first thing we do is to initialize the code +table. We start by adding a code for each of the colors in the +color table. This would be a local color table if one was provided, or +the global color table. (I will be starting all codes with +"#" to distinguish them from color indexes.)

+ + + + + + + + + +
CodeColor(s)
#00
#11
#22
#33
#4Clear Code
#5End Of Information Code
+ +

I added a code for each of the colors in the global color table of +our sample image. I also snuck in two special control codes. (These +special codes are only used in the GIF version of LZW, not in standard +LZW compression.) Our code table is now considered initialized.

+ +

Let me now explain what those special codes are for. The first new code +is the clear code (CC). Whenever you come across the clear code +in the image data, it's your cue to reinitialize the code table. (I'll +explain why you might need to do this in a bit.) The second new code +is the end of information code (EOI). When you come across +this code, this means you've reached the end of the image. Here I've placed +the special codes right after the color codes, but actually the value of +the special codes depends on the value of the LZW minimum code size +from the image data block. If the LZW minimum code size is the same as +the color table size, then special codes immediatly follow the colors; however +it is possible to specify a larger LWZ minimum code size which may leave +a gap in the codes where no colors are assigned. This can be +summarizaed in the following table.

+ +
+ + + + + + + + + +

8#0-#255#256#257
+
+ +

Before we proceed, let me define two more terms. First the index +stream will be the list of indexes of the color for each of +the pixels. This is the input we will be compressing. The code +stream will be the list of codes we generate as output. The +index buffer will be the list of color indexes +we care "currently looking at." The index buffer will contain a list +of one or more color indexes. Now we can step though the LZW +compression algorithm. First, I'll just list the steps. After that +I'll walk through the steps with our specific example.

+ +
    +
  • Initialize code table
    • +
  • Always start by sending a clear code to the code stream.
    • +
  • Read first index from index stream. This value is now the value +for the index buffer
    • +
  • <LOOP POINT>
    • +
  • Get the next index from the index stream to the index buffer. We will +call this index, K
    • +
  • Is index buffer + K in our code table?
    • +
  • Yes: +
      +
    • add K to the end of the index buffer
      • +
    • if there are more indexes, return to LOOP POINT
      • +
    +
    • +
  • No: +
      +
    • Add a row for index buffer + K into our code table with + the next smallest code
      • +
    • Output the code for just the index buffer to our code steam
      • +
    • Index buffer is set to K
      • +
    • K is set to nothing
      • +
    • if there are more indexes, return to LOOP POINT
      • +
    +
    • +
  • Output code for contents of index buffer
    • +
  • Output end-of-information code
    • +
+ +

Seems simple enough, right? It really isn't all that bad. Let's +walk though our sample image to show you how this works. (The steps I +will be describing are summarized in the following table. Numbers +highlighted in green are in the index buffer; numbers in purple are +the current K value.) We have already initialized our code table. We +start by doing two things: we output our clear code (#4) to the code +stream, and we read the first color index from the index stream, 1, +into our index buffer [Step 0].

+ +

Now we enter the main loop of the algorithm. We read the next index +in the index stream, 1, into K [Step 1]. Next we see if we have a +record for the index buffer plus K in the code stream. In this case we +looking for 1,1. Currently our code table only contains single colors +so this value is not in there. Now we will actually add a new row to +our code table that does contain this value. The next available code +is #6, we will let #6 be 1,1. Note that we do not actually send this +code to the code stream, instead we send just the code for the +value(s) in the index buffer. The index buffer is just 1 and the code +for 1 is #1. This is the code we output. We now reset the index buffer +to just the value in K and K becomes nothing. [Step 2].

+ +

We continue by reading the next index into K. [Step 3]. Now K is 1 and the +index buffer is 1. Again we look to see if there is a value in our code +table for the buffer plus K (1,1) and this time there is. (In fact we just +added it.) Therefore we add K to the end of the index buffer and clear out +K. Now our index buffer is 1,1. [Step 4].

+ +

The next index in the index stream is yet another 1. This is our +new K [Step 5]. Now the index buffer plus K is 1,1,1 which we do not +have a code for in our code table. As we did before, we define a new +code and add it to the code table. The next code would be #7; thus #7 += 1, 1, 1. Now we kick out the code for just the values in the index +buffer (#6 = 1,1) to the code stream and set the index buffer to be +K. [Step 6].

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

I've included a few more steps to help you see the pattern. You +keep going until you run out of indexes in the index stream. When +there is nothing new to read, you simply write out the code for +whatever values you may have in your index buffer. Finally you should +send the end-of-information code to the code stream. In this example, +that code is #5. (View the +complete code table.)

+ +

As you can see we dynamically built many new codes for our code +table as we compressed the data. For large files this can turn into a +large number of codes. It turns out that the GIF format specifies a +maximum code of #4095 (this happens to be the largest 12-bit +number). If you want to use a new code, you have to clear out all of +your old codes. You do this by sending the clear code (which for our +sample was the #4). This tells the decoder that you are reinitializing +your code table and it should too. Then you start building your own +codes again starting just after the value for your end-of-information +code (in our sample, we would start again at #6).

+ +

The final code stream would look like this:

+ +

#4 #1 #6 #6 #2 #9 #9 #7 #8 #10 #2 #12 #1 #14 #15 #6 #0 #21 #0 #10 #7 #22 #23 +#18 #26 #7 #10 #29 #13 #24 #12 #18 #16 #36 #12 #5

+ +

This is only 36 codes versus the 100 that would be required without compression.

+ +

LZW Decompression

+ +

At some point we will need to turn this code stream back into +a picture. To do this, we only need to know the values in the stream +and the size of the color table that was used. That's it. You remember that +big code table we built during compression? We actually have enough information +in the code stream itself to be able to rebuild it.

+ +

Again, i'll list the algorithm and then we will walk though an example. Let +me define a few terms i will be using. CODE will be current code we're working +with. CODE-1 will be the code just before CODE in the code stream. {CODE} +will be the value for CODE in the code table. For example, using the code +table we created during compression, if CODE=#7 then {CODE}=1,1,1. +In the same way, {CODE-1} would be the value in the code table for the +code that came before CODE. Looking at step 26 from the compression, +if CODE=#7, then {CODE-1} would be {#9}, not {#6}, which was 2,2.

+ +
    +
  • Initialize code table
    • +
  • let CODE be the first code in the code stream
    • +
  • output {CODE} to index stream
    • +
  • <LOOP POINT>
    • +
  • let CODE be the next code in the code stream
    • +
  • is CODE in the code table?
    • +
  • Yes: +
      +
    • output {CODE} to index stream
      • +
    • let K be the first index in {CODE}
      • +
    • add {CODE-1}+K to the code table
      • +
    +
    • +
  • No: +
      +
    • let K be the first index of {CODE-1}
      • +
    • output {CODE-1}+K to index stream
      • +
    • add {CODE-1}+K to code table
      • +
    +
    • +
  • return to LOOP POINT
    • +
+ +

Let's start reading though the code stream we've created to show how to +turn it back into a list of color indexes. The first value in the code +stream should be a clear code. This means we should initialize our code +table. To do this we must know how many colors are in our color table. +(This information comes from the first byte in the image data block in +the file. More on this later.) Again we will set up codes #0-#3 to be each +of the four colors and add in the clear code (#4) +and end of information code (#5).

+ +

The next step is to read the first color code. In the following table you +will see the values of CODE highlighted in purple, and the values for +CODE-1 highlighted in green. Our first CODE value is #1. We then output +{#1}, or simply 1, to the index stream [Step 0].

+ +

Now we enter the main loop of the algorithm. The next code gets assigned +to CODE which now makes that value #6. Next we check to see if this value +is in our code table. At this time, it is not. This means we must find the +first index in the value of {CODE-1} and call this K. Thus K = first index of +{CODE-1} = first index of {#1} = 1. Now we output {CODE-1} + K to the index +stream and add this value to our code table. The means we output 1,1 and +give this value a code of #6 [Step 1].

+ +

We start the loop again by reading the next code. CODE now would be +#6 and this time we do have a record for this code in our code +table. Thus we dump {#6} to the index stream which would be 1,1. +Now we take the first index in {#6} and call that K. Here, {#6} has +two indexes, the first of which is 1; thus K = 1. Before moving +on, we add {CODE-1}+K to the code table. This #7 is now 1, 1, 1 [Step 2].

+ +

I've included a few more steps so you can see the algorithm in action. While +the explanation may sound complicated, you can see it's actually quite simple. +You'll also notice that you end up building the exact same +code table +as the one that was created during compression. This is the reason that +LZW is so great; we can just share the codes and not the table.

+ +

Saving the Code Stream as Bytes

+ +

I've shown you how to go back and forth between index and code stream, but +haven't told you what to do with them. The index stream is used to specify the +color of each of the pixel of your image and really only shows up on screen. +It is the code stream that is actually saved in the GIF files on your computer +or transmitted over the internet. In order to save these code streams, we must +turn them into bytes. The first thought might be to store each of the codes +as its own byte; however this would limit the max code to just #255 and +result in a lot of wasted bits for the small codes. To solve these problems, +the GIF file format actually uses flexible code sizes.

+ +

Flexible code sizes allow for further compression by limiting the bits +needed to save the code stream as bytes. The code size is the number +of bits it takes to store the value of the code. When we talk about bits, +we're referring to the 1's and 0's that make up a byte. The codes are +converted to their binary values to come up with the bits. To specify +the code for #4, you would look at this binary equivalent, which is 100, +and see that you would need three bits to store this value. The largest code +value in our sample code stream is #36 (binary: 100100) which would +take 6 bits to encode. Note that the number of bits i've just given is +the minimum number. You can make the number take up more bits by adding +zeros to the front.

+ +

GIF image data block layout

+ +

We need a way to know what size each of the codes are. Recall that the +image data block begins with a single byte value called the +LZW minimum code size. The GIF format allows sizes as small +as 2 bits and as large as 12 bits. This minimum code size value is typically +the number of bits/pixel of the image. So if you have 32 colors in your image, +you will need 5 bits/pixel (for numbers 0-31 because 31 in binary is 11111). +Thus, this will most likely be one more than the bit value for the size of the +color table you are using. (Even if you only have two colors, the minimum +code size most be at least 2.) Refer to the +code table above to remind yourself how that works.

+ +

Here's the funny thing: the value for minimum code size isn't +actually the smallest code size that's used in the encoding +process. Because the minimum code size tells you how many bits are +needed just for the different colors of the image, you still have to +account for the two special codes that we always add to the code +table. Therefore the actual smallest code size that will be used is +one more than the value specified in the "minimum" code size +byte. I'll call this new value the first code size.

+ +

We now know how many bytes the first code will be. This size will probably +work for the next few codes as well, but recall that the GIF format +allows for flexible code sizes. As larger code values get added to your +code table, you will soon realize that you need larger code sizes if you +were to output those values. When you are encoding the data, you increase +your code size as soon as your write out the code equal to +2^(current code size)-1. If you are decoding from codes to indexes, +you need to increase your code size as soon as you add the code value that +is equal to 2^(current code size)-1 to your code table. That is, the next +time you grab the next section of bits, you grab one more.

+ +

Note that the largest code size allowed is 12 bits. If you get to this +limit, the next code you encounter should be the clear code which +would tell you to reinitialize the code table. You then go back to using +the first code size and grow again when necessary.

+ +

Jumping back to our sample image, we see that we have a minimum code +size value of 2 which means out first code size will be 3 bits long. +Out first three codes, #1 #6 and #6, would be coded as 001 110 and 110. +If you see at Step 6 of the encoding, we added a code of #7 to our code +table. This is our clue to increase our code size because 7 is equal to +2^3-1 (where 3 is our current code size). Thus, the next code we +write out, #2, will use the new code size of 4 and therefore look +like 0010. In the decoding process, we again would increase our code +size when we read the code for #7 and would read the next 4, rather than +the next 3 bits, to get the next code. In the sample table above this +occurs in Step 2.

+ +

Finally we must turn all these bit values into bytes. The lowest bit of the +code bit value gets placed in the lowest available bit of the byte. After +you've filled up the 8 bits in the byte, you take any left over bits and +start a new byte. Take a look at the following illustration to see +how that works with the codes from our sample image.

+ +

+ +

You can see in the first byte that was returned (8C) that the lowest three bits (because that was +our first code size) contain 110 which is the binary value of 4 so +that would be the clear code we started with, #4. In the three bits to +the left, you see 001 which out or first data code of #1. You can also +see when we switched into code sizes of 4 bits in the second byte +(2D).

+ +

When you run out of codes but have filled less than 8 bits of the +byte, you should just fill the remaining bits with zeros. Recall that +the image data must be broken up onto data sub-blocks. Each +of the data sub-blocks begins with a byte that specifies how many +bytes of data. The value will be between 1 and 255. After you read +those bytes, the next byte indicates again how many bytes of data +follow. You stop when you encounter a subblock that has a lenght of +zero. That tells you when you've reached the end of the image data. In +our sample the image the byte just after the LZW code size is 16 which indicates that 22 bytes of data +follow. After we reach those, we see the next byte is 00 which means we are all done.

+ +

Return codes from bytes the basically just the same process in +reverse. A sample illustration of the process follows which shows how +you would extract codes if the first code size were 5 bits.

+ +

Decoding LZW Bytes

+ +

Next: Animation and Transparency

+ +

That is pretty much everything you need to know to read or generate +a basic image file. One of the reasons the GIF becames such a popular +format was because it also allowed for "fancier" features. These +features include animation and transparency. Next we'll look +at how those work.

What's In A GIF

(animation and transparency)
+ +
+ + +

In addition to being able to store simple image data, +GIF files (specifically GIF89a files) allow for some special features. Tricks +such as transparency and animation can be accomplished with the +help of the Graphics Control Extension block. Here's a sample of what this +block looks like:

+ +

+ +

I'll show you how to manipulate the bytes in this block to achieve +special effects.

+ +

Animation

+ +

Cartoons are created by animators who draw a sequence of pictures, +each slightly different from the one before, which, when rapidly shown +one after the other, give the illusion of motion. Animation in GIF +images is achieved in much the same way. Multiple images may be stored +in the same file and you can tell the computer how much time to wait +before showing the next image. Let's walk though the parts that make +up this simple traffic light animation. +

+ +

+

+ + 47 + 49 + 46 + 38 + 39 + 61 + 0B + 00 + 1D + 00 + A2 + 05 + 00 + FF + 00 + 00 + 00 + FF + 00 + FF + FF + 00 + 8E + 8E + 8E + 00 + 00 + 00 + FF + FF + FF + 00 + 00 + 00 + 00 + 00 + 00 + 21 + FF + 0B + 4E + 45 + 54 + 53 + 43 + 41 + 50 + 45 + 32 + 2E + 30 + 03 + 01 + 00 + 00 + 00 + 21 + F9 + 04 + 04 + 64 + 00 + 00 + 00 + 2C + 00 + 00 + 00 + 00 + 0B + 00 + 1D + 00 + 00 + 03 + 30 + 48 + BA + DC + DE + 23 + BE + 48 + 21 + AD + EB + 62 + A5 + 25 + D3 + 93 + F7 + 8C + E4 + 27 + 9A + 1B + D7 + A1 + 17 + 9B + 1E + A0 + F3 + 96 + 34 + 13 + DC + CF + AD + 37 + 7A + 6F + F7 + B8 + 05 + 30 + 28 + F4 + 39 + 76 + B5 + 64 + 02 + 00 + 21 + F9 + 04 + 04 + 32 + 00 + 00 + 00 + 2C + 02 + 00 + 0B + 00 + 07 + 00 + 10 + 00 + 00 + 03 + 19 + 78 + 27 + AC + CB + 0D + CA + 49 + E1 + B3 + 0A + BB + CD + F7 + F8 + CE + 27 + 1E + 62 + 69 + 9E + A3 + 19 + 82 + 47 + 02 + 00 + 21 + F9 + 04 + 04 + 64 + 00 + 00 + 00 + 2C + 02 + 00 + 02 + 00 + 07 + 00 + 10 + 00 + 00 + 03 + 19 + 78 + 07 + AC + CB + 0D + CA + 49 + E1 + B3 + 0A + BB + CD + F7 + F8 + CE + 27 + 1E + 62 + 69 + 9E + A3 + 19 + 82 + 45 + 02 + 00 + 3B +

+ +

This file is similar to the ones we've previously encountered. The +bytes start out with the GIF header. Next we have a logical +screen descriptor which tells us that our image is 11px by 29 px +and will have a global color table with 8 colors in it (of which we +only really need 5). Immediately after, follows the global color table +which tells us what those colors are (0=red, 1=green, 2=yellow, +3=light grey, 4=black, 5=white, 6=black [not used], 7=black [not used] +).

+ +

Next we encounter an application +extension block. This is this block that causes our animation to +repeat rather than play once and stop. The first three bytes tell us +we are looking at (1) an extension block (2) of type +"application" which is followed by (3) 11 bytes of fixed +length data. These 11 bytes contain the ASCII character codes for +"NETSCAPE2.0". Then begins the actual "application +data" which is contained in sub-blocks. There are two values that +are stored in these sub-blocks. The first value is always the byte +01. Then we have a value in the unsigned +(lo-hi byte) format that says how many times the animation should +repeat. You can see that our sample image has a value of 0; this means +the animation should loop forever. These three bytes are preceded by +the 03 that lets the decoder know that three +bytes of data follow, and they are terminated by 00, the block terminator.

+ +

This very basic animation is essentially made up of three different +"scenes". The first is the one with the green light lit, +the second with the yellow, and the last with the red. You should be +able to see three separate chunks of image data in the bytes +above.

+ + + + + + + + +
123
scene 1: green lightscene 2: yellow lightscene 3: red light
+ +

The first chunk begins immediately after the application extension +block. It is there we encounter our first graphic control +extension. As with all extensions, it begins with 21. Next, the type specific label for the graphic +control type of extension is F9. Next we see +the byte size of the data in the block; this should always be 04. The first of these four data blocks is a +packed field.

+ +

The packed field stores three values. The first three (highest) +bits are "reserved for future use" so those have been left +as zeros. The next three bits indicate the disposal method. The +disposal method specifies what happens to the current image +data when you move onto the next. We have three bits which means we +can represent a number between 0 and 7. Our sample animated image has +a value of 1 which tells the decoder to leave the image in place and +draw the next image on top of it. A value of 2 would have meant that +the canvas should be restored to the background color (as indicated by +the logical screen descriptor). A value of 3 is defined to mean that +the decoder should restore the canvas to its previous state before the +current image was drawn. I don't believe that this value is widely +supported but haven't had the chance to test it out. The behavior for +values 4-7 are yet to be defined. If this image were not animated, +these bits would have been set to 0 which indicates that do not wish +to specify a disposal method. The seventh bit in they byte is the +user input flag. When set to 1, that means that the decoder +will wait for some sort of "input" from the person viewing +the image before moving on to the next scene. I'm guessing it's highly +unlikeley that you will encounter any other value that 0 for this bit. +The final bit is the transparency flag. We will go into more detail +about transparency in the next +section. Since this image isn't using any transparency, we see +this bit has been left at 0.

+ +

The next two bytes are the delay time. This value is in the same +unsigned lformat as all the other integers in the file. This number +represents the number of hundredths of a second to wait before moving +on to the next scene. We see that our sample image has specified +a value of 100 (64 00) +in the first graphics control block which means we would wait 1 second +before changing our green light to yellow.

+ +

Our graphics control extension block ends with the block +terminator 00. You will notice this +type of block appearing two more times in this image, the second +instance differing only in the delay time (the yellow light only +stays up for half a second).

+ +

The next chunk is an image descriptor. The block declares that it +will be drawing an image starting at the top left corner and taking up +the whole canvas (11px x 29px). This block is followed by the image +data that contains all the codes to draw the first scene, the one with +the green light on.

+ + + + + + + + +
Green(Difference)Yellow
green light enlargeddifference between green and yellow imagesyellow light enlarged
+ +

If we compare the first and the second scene, we see they share many +of the same pixel color values. Rather than redrawing the whole canvas, +we can specify just the part that changes (that is, the smallest +rectangle that covers the part that changes). You'll see that the +image descriptor before the second block of image data specifies +that it will start at the pixel at (2, 11) and draws a box that's +7px wide by 16px tall. This is just large enough to cover the bottom two +lights. The works because we chose the "do not dispose" disposal +method for out graphics control extension block. In the same way, +the third and final image data block only renders the top two circles +to both fill in the red and cover up the yellow.

+ +

Transparency

+ +

Normally, GIF images are rectangles that cover up what ever +background may be beneath them. Transparency allows you to "see +though" the image to whatever is below. This is a very simple +trick to pull off in a GIF image. You can set up one color in your +color table that is converted to "invisible ink." Then, as +the image is drawn, whenever this special color is encountered, the +background is allowed to show through.

+ +

There are only two pieces of data we have to set to pull this +off. First we must set the Transparency Color Flag to 1. This is the +lowest bit in the packed byte of the Graphic Control Extension. This +will tell the decoder that we want our image to have a transparent +component. Secondly we must tell the decoder which color we want to +use as our invisible ink. The decoder will then all you to see thought +every pixel that contains this color. Therefore make sure it's not a +color that you are using else where in your image. The color you +choose must be in the active color table and you specify its value in +the Transparent Color Index byte by setting this value to the index of +the color in the color table.

+ +

Let's demonstrate this by revisiting the sample image we used +in Bits and Bytes. We will update this +file to make the white center part transparent. Let's start creating +the Graphic Control Extension block that will do this for us. Again we +start with the 21 F9 +04 punch. In the next byte, we need to flip +the transparent color flag to 1 (we can leave the others at zero) so +this whole byte is simply 01. The next two +bytes can be left at zero.

+ +

We must now specify which color to disappear. Recall that our +sample image had the following global color table:

+ + + + + + + +
IndexColor
0White
1Red
2Blue
3Black
+ +

We already know what we want to make all the white sections +transparent. The color white has an index of 0. Therefore we will +specify a value of 00 for the transparent +color index block. Had we wanted to make the red transparent we would +have used 01, or 02 for blue. Lastly we tack on the block +terminator of 00 and we're done. We have +created the following block:

+ +

+ 21 + F9 + 04 + 01 + 00 + 00 + 00 + 00 +

+ +

Now, all we have to do is plug this into our sample image right before the +image descriptor. I've placed our original sample image on a black background +as well as the one we just made so you can see the results. I've also included +ones where red or blue are transparent. The last three differ by only the +transparent color index byte.

+ + + + + + + + + + + + + + +
OriginalTransparent
+White (00)		Transparent
+Red (01)		Transparent
+Blue (02)
+previous sample +transparent white +transparent red +transparent blue
+ +

This concludes our description of the bits inside GIFs. If you +have not already read the documentation of +the GIFLIB API, you may wish to continue with that.

What's In A GIF

(Bits and bytes)
+ +
+ + +

The authority on the content of GIFs is the GIF89a specification. Originally developed at +CompuServe in the late 1980s, it is now a W3C standard.

+ +

A GIF file is made up of a sequence of data blocks. The first two +blocks are fixed length and fixed format. Later ones are variable +length but self-describing; they consisting of a byte identifying the block +type, followed by a payload length byte, followed by payload.

+ +

The following railroad diagram shows all of the different types of +blocks and where they can be in the file. Every path following the +arrows corresponds to a valid block sequence. The large middle +secction, in particular, can be repeated any number of times.

+ +

GIF file stream diagram

+ +

We will learn more by walking through a sample GIF file. You can +see the sample file and its corresponding bytes below.

+ +

Note that not all possible block types are represented in this +sample file. Later we'll provide samples of missing block types where +appropriate. The different types of blocks include: header, logical screen descriptor, +global color table, graphics control +extension, image descriptor, +local color table, image data, plain text extension, application extension, comment extension, and trailer. Let's get started with the first +block!

+ +

Header Block

+ +

From the sample file: + 47 + 49 + 46 + 38 + 39 + 61 +

+ +

All GIF files must start with a header block. The header takes up +the first six bytes of the file. These bytes should all correspond to +ASCII character codes. The first +three bytes are called the signature. These should +always be "GIF" (ie 47="G", 49="I", +46="F"). The next three specify the version +of the specification that was used to encode the image. + +

Normally the version string will be either "89a" (ie +38="8", 39="9",61="a") or "87a" (ie +38="8", 37="7",61="a"). All modern +GIF-processing software recognizes both versions, For maximum +compatibility, GIFLIB will normally write an 87a signature unless the +file contains GIF89 features.

+ +

+ +

Logical Screen Descriptor

+

From Sample File: 0A + 00 0A 00 91 00 00

+ +

The logical screen descriptor always immediately follows the +header. This block tells the decoder how much room this image will +take up. It is exactly seven bytes long. It starts with the +canvas width and canvas height. +These value can be found in the first two pairs of two bytes each. +Both are 16-bit, nonnegative integers (0-65,535).

+ +

As with all the other multi-byte values in the GIF format, the +least significant byte is stored first (little-endian format). This +means where we would read 0A 00 from the byte stream, we would normally write +it as 000A which is the same as 10. Thus the +width of our sample image is 10 pixels. As a further example 255 would +be stored as FF 00 + but 256 would be 00 01 .

+ +

The canvas width and height are usually ignored by modern viewers. +The GIF format seems to have been designed with the idea that viewers +would render multiple images in a GIF on a common canvas, giving an +effect like a picture wall. But nowadays multiple-image GIFs are +generally used either as animations in which each sub-image is a frame +or as image libraries, with the GIF client handling compositing into +some canvas about which the GIF format holds no information.Thus, the +canvas width and height are mainly fossils. GIFLIB does extract them +and allow you to set them, however.

+ +

The next byte contains four fields of packed data, the "logical +screen descriptor". To understand these, we need to expand the byte + 91 to binary as 10010001 and look at the fields inside it.

+ +

GIF logical screen descriptor block layout

+ +

The first (most-significant) bit is the global color table +flag. If it's 0, then there is no global color table. If it's +1, then a global color table will follow. In our sample image, we can +see that we will have a global color table (as will usually be the +case).

+ +

The next three bits are the color resolution. They +are only meaningful if there is a global color table, and allow you to +compute its size. If the value of this filed is N, the number of +entries in the global color table will be 2 ^ (N+1) - that is, two +raised to the power (N+1). Thus, the 001 in +the sample image represents 2 bits/pixel; 111 would represent 8 bits/pixel.

+ +

The GIF format shows its age here. A more modern design would +simply have allocated a byte or two for color table length. But GIF +was designed when memory was much more expensive than it is today, +and the designers felt strong pressure to economize on every bit. +The consequence is that color table lengths have to be an exact power +of two. Perversely, this can force a waste of memory space in images +with odd color counts.

+ +

The next single bit is the sort flag. If the +values is 1, then the colors in the global color table are sorted in +order of "decreasing importance," which typically means +"decreasing frequency" in the image. This can help the image +decoder, but is not required. In the sample file this value has been +left at 0.

+ +

The sort flag reflected the high cost of dual-port memory at the +time the GIF specification was written in the late 1980s. That kind +of limit disappeared in the mid-1990s, and modern GIF software ignores +this flag. Until version 5.0, GIFLIB ignored it on input and zeroed +it on output; 5.0 and later versions read and preserve it.

+ +

The next byte gives us the background color +index. This byte is only meaningful if the global color table +flag is 1, and if there is no global color table, this byte should be +0.. To understand it you have to remember the original "picture wall" +rendering model for GIFs in which sub-images are composited onto a +larger canvas. It represents which index in the global color table +should be used for pixels on the virtual canvas that aren't overlayed +by an image. GIFLIB supports reading and setting this byte, but modern +viewers and browsers generally have no use for it.

+ +

The last byte of the logical screen descriptor is the pixel +aspect ratio. Modern viewers don't use this. Until 5.0, +GIFLIB ignored this flag on input and zeroed it on output; now it is +read and preserved if present. The GIF standard doesn't give a +rationale for it, but it seems likely that the designers intended it +for representing image captures from the analog television of the day, +which had rectangular pixel-equivalents. The GIF specification says +that if there was a value specified in this byte, N, the actual ratio +used would be (N + 15) / 64 for all N<>0.

+ +

Global Color Table

+ +

From the sample file: + FF + FF + FF + FF + 00 + 00 + 00 + 00 + FF + 00 + 00 + 00 +

+ +

GIFs can have either a global color table or local +color tables for each sub-image. Each color table consists of a list +of RGB (Red-Green-Blue) color component intensities, three bytes for +each color, with intensities ranging from 0 (least) to 255 (most). The +color (0,0,0) is deepest black, the color (255,255,255) brightest +white. The other extreme colors are red at (255,0,0), green at +(0,255,0) and blue at (0,0,255).

+ +

As previously noted, the length of the global color table is +2^(N+1) entries where N is the value of the color depth field in the +logical screen descriptor. The table will take up 3*2^(N+1) bytes in +the stream.

+ +
+ + + + + + + + + + +

+
+ +

Our sample file has a global color table size of 1. This means it +holds 2^(1+1)=2^2=4 colors. We can see that it takes up 12, (3*4), +bytes as expected. We read the bytes three at a time to get each of +the colors. The first color is #FFFFFF (white). This value is given an +index of 0. The second color is #FF0000 (red). The color with an +index value of 2 is #0000FF (blue). The last color is #000000 +(black). The index numbers will be important when we decode the actual +image data.

+ +

Note that this block is labeled as "optional." Not every +GIF has to specify a global color table. However, if the global color +table flag is set to 1 in the logical screen descriptor block, the +color table is then required to immediately follow that block. +

+ +

GIF global color table block layout

+ +

Graphics Control Extension

+ +

From the sample file: + 21 + F9 + 04 + 00 + 00 + 00 + 00 + 00 +

+ +

Graphic control extension blocks are used to specify transparency +settings and control animations. They are an optional GIF89 extension. +The semantics of this extension will be described in detail in a later section +(see Transparency and Animation); +for completeness we'll describe the data fields here.

+ +

The first byte is the extension introducer. All +extension blocks begin with 21. Next is the graphic control +label, F9, which is the value that +flags this as a graphic control extension. Third up is the total +block size in bytes. Next is a packed field. Bits 1-3 +are reserved for future use. Bits 4-6 indicate disposal +method. The penultimate bit is the user input +flag and the last is the transparent color +flag. The delay time value follows in the +next two bytes stored in unsigned format. After that we have the +transparent color index byte. Finally we have the +block terminator which is always 00.

+ +

+ +

Image Descriptor

+ +

From the sample file: + + 2C + 00 + 00 + 00 + 00 + 0A + 00 + 0A + 00 + 00 +

+ +

A single GIF file may contain multiple images. In the original GIF +rendering model these wwere meant to be composited onto a larger +virtual canvas. Nowadays nultiple images are normally used for animations.

+ +

Each image begins with an image descriptor block. This block is +exactly 10 bytes long.

+ +

The first byte is the image separator. Every image +descriptor begins with the value 2C. The +next 8 bytes represent the location and size of the following +image.

+ +

An image in the stream may not necessarily take up the entire +canvas size defined by the logical screen descriptor. Therefore, the +image descriptor specifies the image left position +and image top position of where the image should +begin on the canvas. Both these fields are usually ignored by modern +viewers and browsers.

+ +

Next, this block specifies the image width and +image height. Each of these values is in the +two-byte, unsigned little-endian format. Our sample image indicates +that the image starts at (0,0) and is 10 pixels wide by 10 pixels +tall. (This image does take up the whole canvas size.)

+ +

The last byte is another packed field. In our sample file this byte is 0 so +all of the sub-values will be zero. The first (most significant) bit in +the byte is the local color table flag. Setting this flag +to 1 allows you to specify that the image data that follows uses a different +color table than the global color table. (More information on the local +color table follows.)

+ +

The second bit is the interlace flag. Interlacing +changes the way images are rendered onto the screen in a way that may +reduce annoying visual flicker. The effect of interlacing on a display +is that the first pass of appears immediately, displaying the graphic +as a first as a blur and then sharpenining it up as later passes fill +in lines. That allows the human viewer to at least get an idea of +what's coming up rather than waiting for the entire image to be +painted, line by line. See an +example. To support this, the scan lines of the image need to be +stored in a different order than the normal top-down, separated into +sections that will be rendered in four separate passes.

+ +

+ +

Local Color Table

+

A local color table is organized the same as a global color table. The local +color table would always immediately follow an image descriptor but will only +be there if the local color table flag is set to 1. It is effective only for the +block of image data that immediately follows it. If no local color table +is specified, the global color table is used for the following image data.

+ +

The size of the local color table can be calculated by the value +given in the image descriptor. Just like with the global color table, +if the image descriptor specifies a size of N, the color table will +contain 2^(N+1) colors and will take up 3*2^(N+1) bytes.

+ +

Image Data

+ +

From the sample file: + 02 + 16 + 8C + 2D + 99 + 87 + 2A + 1C + DC + 33 + A0 + 02 + 75 + EC + 95 + FA + A8 + DE + 60 + 8C + 04 + 91 + 4C + 01 + 00

+ +

Finally we get to the actual image data. The image data is composed of +a series of output codes which tell the decoder which colors to emit +to the canvas. These codes are combined into the bytes that make up +the block.

+ +

There's another section on decoding these output code into an image +(see LZW Image Data). Here we'll +just see how to determine how long the block will be.

+ +

The first byte of this block is the LZW minimum code +size. This value is used to decode the compressed output +codes. (Again, see the section on LZW +compression to see how this works.) The rest of the bytes +represent data sub-blocks. Data sub-blocks are are groups of +1 - 256 bytes. The first byte in the sub-block tells you how many +bytes of actual data follow. This can be a value from 0 (00) it 255 (FF). After +you've read those bytes, the next byte you read will tell you now many +more bytes of data follow that one. You continue to read until you +reach a sub-block that says that zero bytes follow. +

+ +

You can see our sample file has a LZW minimum code size of 2. The +next byte tells us that 22 bytes of data follow it (16 hex = 22). After we've read those 22 bytes, we +see the next value is 0. This means that no bytes follow and we have +read all the data in this block.

+ +

GIF image data block layout

+ +

Plain Text Extension

+

Example (not in the sample file): + + 21 + 01 + 0C + 00 + 00 + 00 + 00 + 64 + 00 + 64 + 00 + 14 + 14 + 01 + 00 + 0B + 68 + 65 + 6C + 6C + 6F + 20 + 77 + 6F + 72 + 6C + 64 + 00

+ +

The GIF89 specification allows you to specify text captions to be +overlayed on the following image. This feature never took off; +browsers and image-processing applications such as Photoshop ignore +it, and GIFLIB doesn't try to interpret it.

+ +

The block begins with an extension introducer as all +extension block types do. This value is always 21. +The next byte is the plain text label. This value of +01 is used to distinguish plain text extensions +from all other extensions. The next byte is the block size. +This tells you how many bytes there are until the actual text data begins, or +in other words, how many bytes you can now skip. The byte value will probably be +0C which means you should jump forward 12 bytes. The +text that follows is encoded in data sub-blocks +(see Image Data to see how +these sub-blocks are formed). The block ends when you reach a sub-block of +length 0.

+ +

Application Extension

+

Example (not in sample file): + 21 + FF + 0B + 4E + 45 + 54 + 53 + 43 + 41 + 50 + 45 + 32 + 2E + 30 + 03 + 01 + 05 + 00 + 00 +

+ +

The GIF89 specification allows for application-specific information +to be embedded in the GIF file itself. This capability is not much +used. About the only known public one is the Netscape 2.0 +extension (described below) which is used to loop an animated GIF +file. We'll go into more detail on looping in when we talk about animation.

+ +

The Netscape 2.0 looping block must appear immediately after the +global color table of the logical screen descriptor. It is +19 bytes long. + +

+byte  1        : 33 (hex 0x21) GIF Extension code
+byte  2        : 255 (hex 0xFF) Application Extension Label
+byte  3        : 11 (hex 0x0B) Length of Application Block
+                 (eleven bytes of data to follow)
+bytes 4 to 11  : "NETSCAPE"
+bytes 12 to 14 : "2.0"
+byte  15       : 3 (hex 0x03) Length of Data Sub-Block
+                 (three bytes of data to follow)
+byte  16       : 1 (hex 0x01)
+bytes 17 to 18 : 0 to 65535, an unsigned integer in
+                 little-endian byte format. This specifies the
+                 number of times the loop should
+                 be executed.
+byte  19       : 0 (hex 0x00) a Data Sub-Block Terminator.
+
+

+ +

As with all extensions, we start with 21 +which is the extension introducer. Next is the +extension label which for application extensions is +FF. The next value is the block +size which tells you how many bytes there are before the +actual application data begins. This byte value should be 0B which indicates 11 bytes. These 11 bytes hold +two pieces of information. First is the application +identifier which takes up the first 8 bytes. These bytes +should contain ASCII character codes that identify to which +application the extension belongs. In the case of the example above, +the application identifier is "NETSCAPE" which is +conveniently 8 characters long. The next three bytes are the +application authentication code. The spec says these +bytes can be used to "authenticate the application +identifier." With the Netscape 2.0 extension, this value is simply +a version number, "2.0", hence the extensions name. What +follows is the application data broken into data sub-blocks. As with +the other extensions, the block terminates when you read a sub-block +that has zero bytes of data.

+ +

Comment Extension

+ +

Example (not in sample file): + 21 + FE + 09 + 62 + 6C + 75 + 65 + 62 + 65 + 72 + 72 + 79 + 00

+ +

One last GIF89 extension type is the comment extension. This allows you +to embed ASCII text in a GIF file, and is sometimes used to include an +image description, image credit, or other human-readable metadata such as +the GPS location of the image capture.

+ +

It's probably no surprise by now that the first byte is the +extension introducer which is 21. The next byte is always FE which is the comment label. +Then we jump right to data sub-blocks containing ASCII character codes +for your comment. As you can see from the example we have one data +sub-block that is 9 bytes long. If you translate the character codes +you see that the comment is "blueberry." The final byte, +00, indicates a sub-block with zero bytes +that follow which let's us know we have reached the end of the block.

+ +

GIF comment extension block layout

+ +

Trailer

+ +

From sample file: 3B

+ +

The trailer block indicates when you've reached the end of the file. +It is always a byte with a value of 3B.

+ +

Next: LZW Image Data

+ +

Now that you know what the basic parts of a GIF file are, let's next +focus our attention on how the actual image data is stored and compressed.

These pages explain down +to the bit level what's inside a GIF, and are offered in the hope they +will be useful to programmers using GIFLIB.

The explanation is in three parts:

+ +

    +
  1. Bits and Bytes - first we look at the +file format that makes up a GIF file
    2. +
  2. LZW Image Data - a closer +look at how image data is compressed within a GIF file
    3. +
  3. Transparency and Animation - +how some of the more advanced features of GIF files work

What's In A GIF

(LZW image data)
+ +
+ + +

Now let's look at exactly how we go about storing an image in a GIF +file. The GIF format is a raster format, meaning it stores image data +by remembering the color of every pixel in the image. More +specifically, GIF files remember the index of the color in a color +table for each pixel. To make that clearer, let's review the +sample image we used in the first +section.

+ + + + + + +
+

Actual Size

Color Table

+ + + + + + +
IndexColor
0White
1Red
2Blue
3Black
+
+ +

The color table came from the global color table block. The colors +are listed in the order which they appear in the file. The first color +is given an index of zero. When we send the codes, we always start at +the top left of the image and work our way right. When we get to the +end of the line, the very next code is the one that starts the next +line. (The decoder will "wrap" the image based on the image +dimensions.) We could encode our sample image in the following +way:

+ +

1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 1, +1, 1, 1, 1, 2, 2, 2, 2, 2, 1, 1, 1, 0, 0, 0, 0, 2, 2, 2, 1, 1, 1, +0, 0, 0, 0, 2, 2, 2, ...

+ +

The above listing shows the sequence required to render the first five +lines of the image. We could continue with this method until we've +specified the color for every pixel; however, this can result in a +rather large file. Luckily for us, the GIF format allows us to take +advantage of repetition in our output and to compress our data.

+ +

Much of the following information came from John Barkaus's tutorial +LZW and GIF Explained, which seems to have fallen off the +web. I've tried to provide more detailed samples as well +as illustrations to make the process even clearer

+ +

LZW Compression

+ +

The compression method GIF use is a variant of LZW +(Lempel-Ziv-Welch) compression. To start using this method, we need a +code table. This code table will allow us to use +special codes to indicate a sequence of colors rather than just one at +a time. The first thing we do is to initialize the code +table. We start by adding a code for each of the colors in the +color table. This would be a local color table if one was provided, or +the global color table. (I will be starting all codes with +"#" to distinguish them from color indexes.)

+ + + + + + + + + +
CodeColor(s)
#00
#11
#22
#33
#4Clear Code
#5End Of Information Code
+ +

I added a code for each of the colors in the global color table of +our sample image. I also snuck in two special control codes. (These +special codes are only used in the GIF version of LZW, not in standard +LZW compression.) Our code table is now considered initialized.

+ +

Let me now explain what those special codes are for. The first new code +is the clear code (CC). Whenever you come across the clear code +in the image data, it's your cue to reinitialize the code table. (I'll +explain why you might need to do this in a bit.) The second new code +is the end of information code (EOI). When you come across +this code, this means you've reached the end of the image. Here I've placed +the special codes right after the color codes, but actually the value of +the special codes depends on the value of the LZW minimum code size +from the image data block. If the LZW minimum code size is the same as +the color table size, then special codes immediatly follow the colors; however +it is possible to specify a larger LWZ minimum code size which may leave +a gap in the codes where no colors are assigned. This can be +summarizaed in the following table.

+ +
+ + + + + + + + + +
LWZ Min Code

Code		EOI

6#0-#63#64#65
7#0-#127#128#129
8#0-#255#256#257
+
+ +

Before we proceed, let me define two more terms. First the index +stream will be the list of indexes of the color for each of +the pixels. This is the input we will be compressing. The code +stream will be the list of codes we generate as output. The +index buffer will be the list of color indexes +we care "currently looking at." The index buffer will contain a list +of one or more color indexes. Now we can step though the LZW +compression algorithm. First, I'll just list the steps. After that +I'll walk through the steps with our specific example.

+ +
    +
  • Initialize code table
    • +
  • Always start by sending a clear code to the code stream.
    • +
  • Read first index from index stream. This value is now the value +for the index buffer
    • +
  • <LOOP POINT>
    • +
  • Get the next index from the index stream to the index buffer. We will +call this index, K
    • +
  • Is index buffer + K in our code table?
    • +
  • Yes: +
      +
    • add K to the end of the index buffer
      • +
    • if there are more indexes, return to LOOP POINT
      • +
    +
    • +
  • No: +
      +
    • Add a row for index buffer + K into our code table with + the next smallest code
      • +
    • Output the code for just the index buffer to our code steam
      • +
    • Index buffer is set to K
      • +
    • K is set to nothing
      • +
    • if there are more indexes, return to LOOP POINT
      • +
    +
    • +
  • Output code for contents of index buffer
    • +
  • Output end-of-information code
    • +
+ +

Seems simple enough, right? It really isn't all that bad. Let's +walk though our sample image to show you how this works. (The steps I +will be describing are summarized in the following table. Numbers +highlighted in green are in the index buffer; numbers in purple are +the current K value.) We have already initialized our code table. We +start by doing two things: we output our clear code (#4) to the code +stream, and we read the first color index from the index stream, 1, +into our index buffer [Step 0].

+ +

Now we enter the main loop of the algorithm. We read the next index +in the index stream, 1, into K [Step 1]. Next we see if we have a +record for the index buffer plus K in the code stream. In this case we +looking for 1,1. Currently our code table only contains single colors +so this value is not in there. Now we will actually add a new row to +our code table that does contain this value. The next available code +is #6, we will let #6 be 1,1. Note that we do not actually send this +code to the code stream, instead we send just the code for the +value(s) in the index buffer. The index buffer is just 1 and the code +for 1 is #1. This is the code we output. We now reset the index buffer +to just the value in K and K becomes nothing. [Step 2].

+ +

We continue by reading the next index into K. [Step 3]. Now K is 1 and the +index buffer is 1. Again we look to see if there is a value in our code +table for the buffer plus K (1,1) and this time there is. (In fact we just +added it.) Therefore we add K to the end of the index buffer and clear out +K. Now our index buffer is 1,1. [Step 4].

+ +

The next index in the index stream is yet another 1. This is our +new K [Step 5]. Now the index buffer plus K is 1,1,1 which we do not +have a code for in our code table. As we did before, we define a new +code and add it to the code table. The next code would be #7; thus #7 += 1, 1, 1. Now we kick out the code for just the values in the index +buffer (#6 = 1,1) to the code stream and set the index buffer to be +K. [Step 6].

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

+ +

I've included a few more steps to help you see the pattern. You +keep going until you run out of indexes in the index stream. When +there is nothing new to read, you simply write out the code for +whatever values you may have in your index buffer. Finally you should +send the end-of-information code to the code stream. In this example, +that code is #5. (View the +complete code table.)

+ +

As you can see we dynamically built many new codes for our code +table as we compressed the data. For large files this can turn into a +large number of codes. It turns out that the GIF format specifies a +maximum code of #4095 (this happens to be the largest 12-bit +number). If you want to use a new code, you have to clear out all of +your old codes. You do this by sending the clear code (which for our +sample was the #4). This tells the decoder that you are reinitializing +your code table and it should too. Then you start building your own +codes again starting just after the value for your end-of-information +code (in our sample, we would start again at #6).

+ +

The final code stream would look like this:

+ +

#4 #1 #6 #6 #2 #9 #9 #7 #8 #10 #2 #12 #1 #14 #15 #6 #0 #21 #0 #10 #7 #22 #23 +#18 #26 #7 #10 #29 #13 #24 #12 #18 #16 #36 #12 #5

+ +

This is only 36 codes versus the 100 that would be required without compression.

+ +

LZW Decompression

+ +

At some point we will need to turn this code stream back into +a picture. To do this, we only need to know the values in the stream +and the size of the color table that was used. That's it. You remember that +big code table we built during compression? We actually have enough information +in the code stream itself to be able to rebuild it.

+ +

Again, i'll list the algorithm and then we will walk though an example. Let +me define a few terms i will be using. CODE will be current code we're working +with. CODE-1 will be the code just before CODE in the code stream. {CODE} +will be the value for CODE in the code table. For example, using the code +table we created during compression, if CODE=#7 then {CODE}=1,1,1. +In the same way, {CODE-1} would be the value in the code table for the +code that came before CODE. Looking at step 26 from the compression, +if CODE=#7, then {CODE-1} would be {#9}, not {#6}, which was 2,2.

+ +
    +
  • Initialize code table
    • +
  • let CODE be the first code in the code stream
    • +
  • output {CODE} to index stream
    • +
  • <LOOP POINT>
    • +
  • let CODE be the next code in the code stream
    • +
  • is CODE in the code table?
    • +
  • Yes: +
      +
    • output {CODE} to index stream
      • +
    • let K be the first index in {CODE}
      • +
    • add {CODE-1}+K to the code table
      • +
    +
    • +
  • No: +
      +
    • let K be the first index of {CODE-1}
      • +
    • output {CODE-1}+K to index stream
      • +
    • add {CODE-1}+K to code table
      • +
    +
    • +
  • return to LOOP POINT
    • +
+ +

Let's start reading though the code stream we've created to show how to +turn it back into a list of color indexes. The first value in the code +stream should be a clear code. This means we should initialize our code +table. To do this we must know how many colors are in our color table. +(This information comes from the first byte in the image data block in +the file. More on this later.) Again we will set up codes #0-#3 to be each +of the four colors and add in the clear code (#4) +and end of information code (#5).

+ +

The next step is to read the first color code. In the following table you +will see the values of CODE highlighted in purple, and the values for +CODE-1 highlighted in green. Our first CODE value is #1. We then output +{#1}, or simply 1, to the index stream [Step 0].

+ +

Now we enter the main loop of the algorithm. The next code gets assigned +to CODE which now makes that value #6. Next we check to see if this value +is in our code table. At this time, it is not. This means we must find the +first index in the value of {CODE-1} and call this K. Thus K = first index of +{CODE-1} = first index of {#1} = 1. Now we output {CODE-1} + K to the index +stream and add this value to our code table. The means we output 1,1 and +give this value a code of #6 [Step 1].

+ +

We start the loop again by reading the next code. CODE now would be +#6 and this time we do have a record for this code in our code +table. Thus we dump {#6} to the index stream which would be 1,1. +Now we take the first index in {#6} and call that K. Here, {#6} has +two indexes, the first of which is 1; thus K = 1. Before moving +on, we add {CODE-1}+K to the code table. This #7 is now 1, 1, 1 [Step 2].

+ +

I've included a few more steps so you can see the algorithm in action. While +the explanation may sound complicated, you can see it's actually quite simple. +You'll also notice that you end up building the exact same +code table +as the one that was created during compression. This is the reason that +LZW is so great; we can just share the codes and not the table.

+ +

Saving the Code Stream as Bytes

+ +

I've shown you how to go back and forth between index and code stream, but +haven't told you what to do with them. The index stream is used to specify the +color of each of the pixel of your image and really only shows up on screen. +It is the code stream that is actually saved in the GIF files on your computer +or transmitted over the internet. In order to save these code streams, we must +turn them into bytes. The first thought might be to store each of the codes +as its own byte; however this would limit the max code to just #255 and +result in a lot of wasted bits for the small codes. To solve these problems, +the GIF file format actually uses flexible code sizes.

+ +

Flexible code sizes allow for further compression by limiting the bits +needed to save the code stream as bytes. The code size is the number +of bits it takes to store the value of the code. When we talk about bits, +we're referring to the 1's and 0's that make up a byte. The codes are +converted to their binary values to come up with the bits. To specify +the code for #4, you would look at this binary equivalent, which is 100, +and see that you would need three bits to store this value. The largest code +value in our sample code stream is #36 (binary: 100100) which would +take 6 bits to encode. Note that the number of bits i've just given is +the minimum number. You can make the number take up more bits by adding +zeros to the front.

+ +

GIF image data block layout

+ +

We need a way to know what size each of the codes are. Recall that the +image data block begins with a single byte value called the +LZW minimum code size. The GIF format allows sizes as small +as 2 bits and as large as 12 bits. This minimum code size value is typically +the number of bits/pixel of the image. So if you have 32 colors in your image, +you will need 5 bits/pixel (for numbers 0-31 because 31 in binary is 11111). +Thus, this will most likely be one more than the bit value for the size of the +color table you are using. (Even if you only have two colors, the minimum +code size most be at least 2.) Refer to the +code table above to remind yourself how that works.

+ +

Here's the funny thing: the value for minimum code size isn't +actually the smallest code size that's used in the encoding +process. Because the minimum code size tells you how many bits are +needed just for the different colors of the image, you still have to +account for the two special codes that we always add to the code +table. Therefore the actual smallest code size that will be used is +one more than the value specified in the "minimum" code size +byte. I'll call this new value the first code size.

+ +

We now know how many bytes the first code will be. This size will probably +work for the next few codes as well, but recall that the GIF format +allows for flexible code sizes. As larger code values get added to your +code table, you will soon realize that you need larger code sizes if you +were to output those values. When you are encoding the data, you increase +your code size as soon as your write out the code equal to +2^(current code size)-1. If you are decoding from codes to indexes, +you need to increase your code size as soon as you add the code value that +is equal to 2^(current code size)-1 to your code table. That is, the next +time you grab the next section of bits, you grab one more.

+ +

Note that the largest code size allowed is 12 bits. If you get to this +limit, the next code you encounter should be the clear code which +would tell you to reinitialize the code table. You then go back to using +the first code size and grow again when necessary.

+ +

Jumping back to our sample image, we see that we have a minimum code +size value of 2 which means out first code size will be 3 bits long. +Out first three codes, #1 #6 and #6, would be coded as 001 110 and 110. +If you see at Step 6 of the encoding, we added a code of #7 to our code +table. This is our clue to increase our code size because 7 is equal to +2^3-1 (where 3 is our current code size). Thus, the next code we +write out, #2, will use the new code size of 4 and therefore look +like 0010. In the decoding process, we again would increase our code +size when we read the code for #7 and would read the next 4, rather than +the next 3 bits, to get the next code. In the sample table above this +occurs in Step 2.

+ +

Finally we must turn all these bit values into bytes. The lowest bit of the +code bit value gets placed in the lowest available bit of the byte. After +you've filled up the 8 bits in the byte, you take any left over bits and +start a new byte. Take a look at the following illustration to see +how that works with the codes from our sample image.

+ +

+ +

You can see in the first byte that was returned (8C) that the lowest three bits (because that was +our first code size) contain 110 which is the binary value of 4 so +that would be the clear code we started with, #4. In the three bits to +the left, you see 001 which out or first data code of #1. You can also +see when we switched into code sizes of 4 bits in the second byte +(2D).

+ +

When you run out of codes but have filled less than 8 bits of the +byte, you should just fill the remaining bits with zeros. Recall that +the image data must be broken up onto data sub-blocks. Each +of the data sub-blocks begins with a byte that specifies how many +bytes of data. The value will be between 1 and 255. After you read +those bytes, the next byte indicates again how many bytes of data +follow. You stop when you encounter a subblock that has a lenght of +zero. That tells you when you've reached the end of the image data. In +our sample the image the byte just after the LZW code size is 16 which indicates that 22 bytes of data +follow. After we reach those, we see the next byte is 00 which means we are all done.

+ +

Return codes from bytes the basically just the same process in +reverse. A sample illustration of the process follows which shows how +you would extract codes if the first code size were 5 bits.

+ +

Decoding LZW Bytes

+ +

Next: Animation and Transparency

+ +

That is pretty much everything you need to know to read or generate +a basic image file. One of the reasons the GIF becames such a popular +format was because it also allowed for "fancier" features. These +features include animation and transparency. Next we'll look +at how those work.

It was described +by a GIF standard issued in 1987 and revised in 1989. A copy of the +GIF89 standard is included in the doc/ directory. + +This code originated as a linkable library for DOS programs, together +with command-line tools for generating and viewing and analyzing GIF +images. The DOS code was written by Gershon Elber using Borland C +under MS-DOS sometime between the issue of GIF87 and mid-1989 (1.0 was +dated 14 June 1989; one portion, getarg.c, was dated 11 Mar 88). + +At some time no later than the end of 1989 Eric S. Raymond (aka "ESR") +ported this DOS version to System V Unix. Between 1989 and 1992 ESR +reworked various portions of the API, improving and simplifying +the code's interface. + +ESR's 2.1 version was the first to include the DGifSlurp()/EGifSpew() +function pair for enabling non-sequential operations on GIF images +(also the tools icon2gif, gifovly, and gifcompose; the last was +removed in 5.0). + +ESR's Unix port was incorporated into the NCSA/Netscape browser in +1994, which is how GIF became (with JPEG) one of the two most popular +image formats on the early Web. + +Beginning around 1993, patent claims by Unisys over the LZW +compression method used in GIF theatened adverse legal consequences +for users and developers of programs incorporating the format. The +threats became serious in 1999, with Unisys demanding license fees +for any software using the format. + +One response to this was the development of PNG in 1995. Another was +that ESR sought a lead developer outside the U.S. to hand the project off +to, and passed it to Toshio Kuratomi. ESR remembers this as happening +in 1994, but that date could be wrong as some headers imply 3.0 was issued +under ESR's name in 1996. But other files do date Toshio's first release +to 1994. Toshio shipped 4.0 in December 1998. + +Subsequently, the project shipped for some time as "libungif" with +support for compressed GIFs removed to avoid the LZW patent issues. +Compression support was merged back in after the last blocking patent +expired in 2004; this became release 4.0.0. After that merge the +code was again known as giflib. + +By 2006, support for PNGs was sufficiently universal that GIF could be +described as a legacy format. Anything you can do with it GIF could +probably be better done with PNG. Nevertheless (and despite efforts +like "Burn All GIFs Day" in November 1999) the GIF format has remained +widely popular. + +In April 2012 ESR rejoined the project to do some code cleanups +and auditing, and Toshio Kuratomi asked him to take back the lead. +ESR released version 4.2 in May 2012. + +Version 5.0, released in June 2012, fulfilled almost all the to-do +items from 18 years of backlog. It made the library thread-safe, added +direct support for GIF89 graphics control blocks, and tossed out large +amounts of obsolete utility code. + +This code is very old, very stable, and *everywhere* - browsers +game consoles, smartphones, pretty much everything that opens an +HTTP port and does graphics uses it. + +The utilities in this source tree were important as GIF production +tools early in the format's history, but have been superseded by +multi-format viewers and editors.

The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. Some packages provide this +`INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + + The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type `make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the `make install' phase executed with root + privileges. + + 5. Optionally, type `make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior `make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type `make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide `make + distcheck', which can by used by developers to test that all other + targets like `make install' and `make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. This +is known as a "VPATH" build. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the +default for these options is expressed in terms of `${prefix}', so that +specifying just `--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to `configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +`make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, `make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +`${prefix}'. Any directories that were specified during `configure', +but not in terms of `${prefix}', must each be overridden at install +time for the entire installation to be relocated. The approach of +makefile variable overrides for each directory variable is required by +the GNU Coding Standards, and ideally causes no recompilation. +However, some platforms have known limitations with the semantics of +shared libraries that end up requiring recompilation when using this +method, particularly noticeable in packages that use GNU Libtool. + + The second method involves providing the `DESTDIR' variable. For +example, `make install DESTDIR=/alternate/directory' will prepend +`/alternate/directory' before all installation names. The approach of +`DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of `${prefix}' +at `configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of `make' will be. For these packages, running `./configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with `make V=1'; while running `./configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with `make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX `make' updates targets which have the same time stamps as +their prerequisites, which makes it generally unusable when shipped +generated files such as `configure' are involved. Use GNU `make' +instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put `/usr/ucb' early in your `PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in `/usr/bin'. So, if you need `/usr/ucb' +in your `PATH', put it _after_ `/usr/bin'. + + On Haiku, software installed for all users goes in `/boot/common', +not `/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf limitation. Until the limitation is lifted, you can use +this workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: + for more details, including other options available for fine-tuning + the installation locations. + +`--no-create' +`-n' + Run the configure checks, but stop before creating any output + files. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. diff -Nru giflib-4.1.6/giflib-5.0.5/install-sh giflib-5.0.5-2/giflib-5.0.5/install-sh --- giflib-4.1.6/giflib-5.0.5/install-sh 1970-01-01 00:00:00.000000000 +0000 +++ giflib-5.0.5-2/giflib-5.0.5/install-sh 2015-01-05 11:51:27.000000000 +0000 @@ -0,0 +1,527 @@ +#!/bin/sh +# install - install a program, script, or datafile + +scriptversion=2011-11-20.07; # UTC + +# This originates from X11R5 (mit/util/scripts/install.sh), which was +# later released in X11R6 (xc/config/util/install.sh) with the +# following copyright and license. +# +# Copyright (C) 1994 X Consortium +# +# Permission is hereby granted, free of charge, to any person obtaining a copy +# of this software and associated documentation files (the "Software"), to +# deal in the Software without restriction, including without limitation the +# rights to use, copy, modify, merge, publish, distribute, sublicense, and/or +# sell copies of the Software, and to permit persons to whom the Software is +# furnished to do so, subject to the following conditions: +# +# The above copyright notice and this permission notice shall be included in +# all copies or substantial portions of the Software. +# +# THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +# IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +# FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

Some internal manual +pages are not to be installed. + +Version 5.0.4 +============= + +Fix for a rare misrendering bug when a GIF overruns the decompression-code +table. The image on which this was spotted was a relatively long-running +animated GIF; still images of ordinary size should have been immune. + +Version 5.0.3 +============= + +Fix a build-system glitch so it will install manpages. + +Version 5.0.2 +============= + +Documentation and polish +------------------------ +* Partial build is now possible on systems without xmlto. + +Code Fixes +---------- +* Change unused return of EGifSetGifVersion() to void. +* Buffer overrun prevention in gifinto. + +Version 5.0.1 +============= + +Documentation and polish +------------------------ +* There is now an installable manual page for the GIFLIB utility kit. + +Retirements +----------- +* gifinter is gone. Use convert -interlace from the ImageMagic suite. + +Code Fixes +---------- +* In 5.0.0 the private gif89 bit wasn't being guaranteed cleared at + the beginning of EGifGetGifVersion(); this occasionally led to an + incorrect version prefix being issued dependent on the state of + malloced memory. +* An EGifSetGifVersion() function taking a GifFile argument has been + added for use with the low-level sequential API. This change requires + a bump of the library revision number. + +Version 5.0.0 +============= + +Changes to the API require a library major-version bump. Certain +initialization functions have acquired an integer address argument for +passing back an error code, in order to avoid thread-unsafe static +storage. Application code using extension blocks will require minor +changes. A few functions have been renamed. + +Code Fixes +---------- +* Fixes applied for CVE-2005-2974 and CVE-2005-3350 + This closes Debian bug #337972. + +New API Features +---------------- + +Thread Safety +~~~~~~~~~~~~~ +The library is now completely re-entrant and thread-safe. + +* Library error handling no longer uses a static cell to store the last + error code registered; that made the library thread-unsafe. For functions + other than GIF file openers, the code is now put in an Error member of + the GifFileType structure. The GifError() amd GifLastError() functions + that referenced that static cell are gone, and the GifErrorString() + function introduced in the 4.2 release now takes an explicit error code + argument. +* GIF file openers - DGifOpenFileName(), DGifOpenFileHandle(), DGifOpen(), + EGifOpenFileName(), EGifOpenFileHandle(), and EGifOpen() - all now take + a final integer address argument. If non-null, this is used to pass + back an error code when the function returns NULL. + +Extensions +~~~~~~~~~~ +The ExtensionBlock API has been repaired, solving some problems with GIF89 +extension handling in earlier versions. + +* DGifSlurp() and EGifSpew() now preserve trailing extension blocks with + no following image file. +* Three documented functions - EGifPutExtensionFirst(), EGifPutExtensionNext(), + and EGifPutExtensionLast() - have been relaced by new functions + EGifPutExtensionLeader(), EGifPutExtensionBlock(), and + EGifPutExtensionTrailer(). See the Compatibility section of + the library API documentation for details. +* New functions DGifSavedExtensionToGCB() and EGifGCBToSavedExtension() + make it easy to read and edit GIF89 graphics control blocks in saved images. + +Namespacing +~~~~~~~~~~~ +All functions exported by giflib now have DGif, EGif, or Gif as a name prefix. + +* Three documented functions - MakeMapObject(), FreeMapObject(), and + UnionColorMap() - have been renamed to GifMakeMapObject(), + GifFreeMapObject(), and GifUnionColorMap() respectively. +* The library Draw* functions are now prefixed GifDraw*, and the + text-drawing ones are suffixed with "8x8". This fixes a conflict + with the Windows API and leaves the door open for more general text-drawing + functions with different font sizes. + +Other changes +~~~~~~~~~~~~~ +* DGifSlurp() and EGifSpew() now read and write interlaced images properly. +* The amazingly obscure colormap sort flag and pixel aspect ratio + features of GIF are now read and preserved, for whatever good that + may do. +* Six undocumented functions have been renamed; five of these take additional + or slightly different argument types. See the Compatibility section of + the library API documentation for details. +* There's now an EGifGetGifVersion() that computes the version EGifSpew() + will write. +* QuantizeBuffer() has been returned to the core library as GifQuantizeBuffer() + - turns out some important applications (notably mplayer) were using it. +* TRUE and FALSE macros are gone, also VoidPtr. No more namespace pollution. +* Various arguments have been made const where possible. + +Retirements +----------- +* The (undocumented) gifinfo utility is gone. Use giftool -f instead. +* The gifburst utility is gone. Everybody has image viewers that + can pan now, and removing it gets rid of a dependency on Perl. +* gifcompose is gone. It was a decent idea when I wrote it in 1989, + but I did the same thing better and cleaner a decade later with + PILdriver in the PIL package. Removing it gets rid of a dependency + on shell. +* gif2x11 gifasm, gifcomb, gifflip, gifovly, gifpos, gifresize, and gifrotate + are all gone. The ImageMagick display(1)/convert(1) utilities and PILdriver + do these things better and in a format-independent way. +* Lennie Araki's Windows C++ wrapper is gone. It's eight years old, + unmaintained, he has dropped out of sight, and a better one needs to + be written to use the high-level GIFLIB API and GIF89 graphics + control extension support. We'll carry such a wrapper when we have + a maintainer for it. +* EGifSetVersion(), introduced in 4.2, is gone. The library always + writes GIF87 or GIF89 as required by the data. This change helps + with thread safety. + +Utilities +--------- +* Several utilities have been renamed to (a) fix last-century's habit + of arbitarily smashing vowels out of names to make them just one or two + characters shorter, (b) ensure that every utility in this set has 'gif' + as a name prefix. Here's the list: + + giffiltr -> giffilter + gifspnge -> gifsponge + icon2gif -> gifbuild + text2gif -> gifecho + raw2gif -> gif2raw + +* To go with its new name, gif2raw now dumps raw pixels from a GIF if the + (previously required) size option is missing. +* Standalone rgb2gif is gone; the same capability is now a mode of gif2rgb. +* giftext displays the parsed contents of GIF89 graphics control blocks. +* gifbuild handles GIF89 graphics control blocks and Netscape animation + loop blocks; it can can display and update either. +* gifrotate and other filter utilities now preserve extension blocks, + including the graphics control information for transparency and delay time. +* A new utility, giftool, supports a wide variety of filtering operations + on GIFs, including: setting background and transparency colors, changing + interlacing, setting image delays, setting the user-input flag, and setting + the aspect-ratio byte. It can sequence multiple operations. +* The test-pattern generators gifbg, gifcolor, gihisto and gifwedge and the + code templates giffilter and gifsponge are no longer installed by default. + +Documentation and polish +------------------------ +* The history.txt and build.txt and files from 4.2.0 now have .asc extensions + to indicate that they use asciidoc markup, contrasting with the txt + standards files from CompuServe. +* The documentation now includes "What's In A GIF", a very detailed narrative + description of the file format. +* The -A option of gifasm (for inserting a loop control block) is documented. +* The documentation directory includes a copy of the original GIF87 + specification as well as GIF89's. +* The project now has a logo. + +Version 4.2.0 +============= + +Now maintained by ESR again after handoff by Toshio Kuratomi. + +Code Fixes +---------- +* Code updated internally to C99 to enable more correctness checks by + the compiler. Compiles under GCC 4.6.1 without errors or warnings. +* A rare resource leak in the colormap-object maker was found with + Coverity and fixed. +* The code now audits clean under Coverity and cppcheck. +* splint cleanup begun, there's a lot of work still to do on this. + +New API Features +---------------- +* The default GIF version to write is now computed at write time from + the types of an image's extension blocks, but can be overridden with + EGifSetGifVersion(). +* EGifSpew() is now thread-safe. +* Two new functions, GifError() and GifErrorString(), + return the error state in a form that can be used by programs. +* Two library functions - EGifOpenFileName() and EGifPutImageDesc() - + now have bool rather than int flag arguments. Since bool is a + typedef of int and TRUE/FALSE have been redefined to true/false, + both source and object compatibility with older library versions + should be preserved. +* GAGetArgs(), used only in the utilities, now returns bool rather + than int. +* The undocumented GIF_LIB_VERSION symbol is gone from the library header. + It has been replaced with three documented symbols: GIFLIB_MAJOR, + GIFLIB_MINOR, and GIFLIB_RELEASE. + +Retirements +----------- +* The gif2epsn and gif2iris utilities are gone. They were full of + platform dependencies for platforms long dead. There are enough + platform-independent GIF viewers in the world that these weren't + adding any value. Removing these gets rid of a dependency on GL. +* The rle2gif, gif2rle, and gif2ps utilities are also gone. There are enough + multiformat image converters in the world that these weren't adding + any value either. Removing them reduces the codebase's dependencies. +* The undocumented DumpScreen2Gif() is gone from the library. The + only non-obsolete capture mode it supported was through X, and that + probably hasn't been used in years and is replaceable by any number + of capture utilities. Dropping this code makes the library's + portability issues go away. +* QuantizeBuffer(), GifQprintf(), PrintGifError(), GIF_ERROR() + and GIF_MESSAGE() have been removed from the core library. + They were used only by the utilities. QuantizeBuffer() has been + inlined where it was used and the latter three are now part of the + utility support library. +* The Game Boy Advanced test code is gone. The platform was discontinued + in 2008; more to the point, nobody ever documented the code's assumptions + or expected results. +* The Changelog file is now retained for archival purposes only, and because + autotools throws a hissy fit if there isn't one. The single point of + truth about changes and the reasons for them is the repository history. + +Behavior changes +---------------- +* The -q option of the utilities is replaced by an opposite -v (verbose) + option; the default is now quiet for all platforms. Defaulting to chattiness + on MSDOS made sense in a world of slow text consoles, but not today. + +Testing +------- +* There is now a proper regression-test suite; run 'make' in tests/. + The old test-unx script is now tests/visual-check and can be run + occasionally for a check with the Mark One Eyeball. + +Documentation +------------- +* Build instructions now live in build.txt +* An overview of the giflib API now lives in api.txt. +* Documentation is now in DocBook-XML, so either HTML or man pages can + be generated from it. + +Version 4.1.6 +============= +Brown paper bag release. Fix a problem with header inclusion that could +prevent the library from building on some platforms. + +Version 4.1.5 +============= +This version has some important fixes for segfaults when working with corrupt +files. All users are strongly encouraged to upgrade. + +Code Fixes +---------- +* Fix segfault in utilities due to referencing ColorMaps in GifFiles that had + no ColorMap present. +* Fix gif2x11 to work on 24 bit displays. +* Fix for giftext segfault when the GifFile does not store a global colormap. +* Checks to fail gracefully when an image contains improper LZ codes. +* Close file handles on failure in DGifOpenFileHandle() +* Checks to operate on files in binary mode on WIN32 as well as MSDOS. + +Building +-------- +* Add checks to make building on Win32 easier. +* Allow turning off gl_s, rle, and X11 support from the configure command line. +* Fix for finding a 32 bit integer type on some platforms. +* Only enable -Wall if we're using gcc. + +Version 4.1.4 +============= +This version fixes some bugs with deallocating ColorMaps. Fix building on +several platforms. Fix x86_64 builds to not hang the encoder. + +* Fix several areas in decoding where we removed a ColorMap from our GifFile + but didn't set the pointer to NULL. This could lead to double free's of + the ColorMap. +* Fix a bug in dev2gif.c where we redefined some gl types incorrectly. +* Fix a bug in the gif LZW encoder that was triggered on modern 64 bit + platforms. +* Fix building on Windows. Note -- there has been one API changing event for + Windows (renaming DrawText to DrawGifText.) This should have conflicted with + Windows API and therefore caused the builds to fail previously. If you had + it working with DrawText before, apologies, you'll need to change to + DrawGifText in your code. This only affects Windows. +* Add support for building on The Game Boy Advance. Note: Due to the GBA's + limited memory, the API for the GBA uses short's in many places where the + other platforms use ints. This shouldn't affect anyone unless you've + been able to get an older version of the code to run on GBA and want to + start using this version instead. A recompile of your dependent code + will be necessary in this case. + +Version 4.1.3 +============= +This version fixes some bugs in the Extension writing code in +EGifPutExtensionFirst, Next, and Last. Using these functions, it is possible +to output extensions that contain multiple subblocks. Additionally, library +code has been updated to use these functions, making it safe to output +long Comments, and multi-block extensions read in from another file. + +* giflib is now hosted on sourceforge with libungif: + http://sourceforge.net/projects/libungif +* Make the EGifPutExtension{First,Next,Last} family of functions use WRITE + so user defined WRITE methods will output them correctly. +* Modify EGifSpew and EGifPutComment to use EGifPutExtension{First,Next,Last} + so we won't output broken GIFs when dealing with GIFs with multiple + subblocks. +* More -Wall fixes revealed while testing on Solaris and FreeBSD. +* Updated the gif_lib.html documentation to not use EGifPutExtension when + dealing with multiple subblocks. Use EGifPutExtension{First,Next,Last} + instead. +* Some Windows code from the old CVS repository now available in the windows + subdirectory. I don't have a Windows environment to test and maintain this + but maybe someone out there will find it useful. Caveat hacker. + +Version 4.1.2 +============= +* Numerous bug fixes from people on the old libungif mailing list. +* GIF_ERROR and GIF_MESSAGE are on the deprecation list as they are also + utility helper functions rather than essential to the functioning of the + library. +* Complete deprecation list is now in the README file +* Audited the sources with gcc -Wall. Everything detectable has now been fixed. +* Ran the library code through indent. + +Version 4.1.1 +============= +* Merge in many bug fixes that were sent in while I was hiking the + Appalachian Trail. +* The qprintf methods of the library are now deprecated. Do not use + GifQuietPrint or GifQprintf. These should have been pushed out into the + utility helper library instead of sitting around in the library proper at + the same time as the getarg functions were moved out. Getting rid of these + will let us get rid of our dependence on stdarg.h/varargs.h (Which a Gif + reading library has no business requiring.) + +Version 4.1.0 +============= +* Several minor memory leaks in error conditions have been plugged. +* New Function EGifOpen(void *userData, OutputFunc writeFunc) allows user + specified gif writing functions. +* Old copyright notices in a few source files have been updated. All library + copyrights should now reflect the copyright notice in the COPYING file. + +Version 4.0.0 -- giflib +======================= +This version of the giflib library merges Eric Raymond's giflib-3.0 release +with the libungif-4.0 release to give people a binary compatible choice +between the two libraries and gives me the chance to add bugfixes to giflib +that have been incorporated in libungif. + +PLEASE READ THE FILE PATENT_PROBLEMS BEFORE USING THIS LIBRARY! + +Version 4.0.0 +============= +Major fixes have been made to the code that handles Extensions. +Unfortunately, this causes binary incompatibility with giflib-3.0 and +libungif-3.x. However, the API is still intact. I am, however, deprecating +the use of saveImage[x].Function. Use +saveImage[x].ExtensionBlocks[y].Function instead. + +Version 3.1.1 +============= + The following bugs which caused SegFaults have been fixed: + * When reading gif files with extensions, DGifSlurp would violate memory. + * When closing a gif that had a local colormap, DGifCloseFile would attempt + to free the colormap twice. + * Fix a potential memory leak in DGifSlurp. + * New function DGifOpen to allow specifying a user definable gif reading + function. + +Version 3.1.0 +============= + * Add a new function: + GifFileType *DGifOpen(void * userData, InputFunc readFunc) + to read the gif image from a user defined input function. + * A few bugfixes. + +Version 3.0 +=========== + +Changes from Eric Raymond's libgif +---------------------------------- +* A new gif encoder that makes uncompressed gifs rather than standard, + LZW-compressed gifs. This is actually the major motivating factor behind + libungif; to provide third-party distributors a means to provide a gif + library without the patented LZW encoder. +* A new configure script to make compilation of the library on multiple + platforms easier. The package should now build shared libraries on all + platforms supported by GNU libtool. +* Removed the getarg functions from libgif. These were not part of the + public API and only used by the tools in the utils directory so I separated + them from the rest of the library. +* Fixed a few bugs in the tools in the utils directory. + +Version 3.0 +=========== + +New features +------------ +* Incorporated Sirtaj Kang's changes to make both static and shared libs. +* All the utility and library docs are HTML now. +* The library and relevant utilities are now fully GIF89-aware. +* Functions for drawing text and boxes on saved images are documented. +* The distribution is now issued under a simple X-Consortium-style license. +* Can now generate package RPMs and LSM automatically. +* Home page with Web-acessible documentation at http://www.ccil.org/~esr/giflib + +Bug fixes +--------- +* Fix giftext to not core dump on a null extension record. +* Incorporate Philip VanBaren's change to prevent a core dump in gifasm. + +Version 2.3 +=========== +* Fixed a core-dump bug in gifcomb revealed by ELF environment in Linux 1.2.13. + +Version 2.2b +============ +* Added gifburst tool. + +Version 2.2 +=========== +* Linux is supported. + +Version 2.1 +=========== +* Added the gifovly tool, which supports making a composite from several GIF + images. +* Used gifovly to implement a full-fledged pasteup program in shell. It's + called gifcompose and lives in the util directory. +* Added a copy of the GIF89 standard to the doc directory (gif89.txt); + also a description of the preferred compression method (lzgif.txt). + +Version 2.0 +=========== + With this version, development was taken over from Gershon Elber by Eric +S. Raymond . Note that I, esr, have pretty much +adhered to Gershon's coding style, even though it's quite baroque and DOS- +headed by my standards. + +Library Improvements +-------------------- +* New DGifSlurp() and EGifSpew() library entry points allow all GIF-bashing + to be done in core on machines with sufficient memory. Writing code to + slice'n'dice multiple GIFs in non-sequential ways is now much easier (send + kudos and brickbats to esr, small unmarked bills preferred). +* The interface has changed somewhat. Members in the GifFileType structure + have been renamed and regrouped. This was required for support of the + SavedImages member (which enables the new functions mentioned in 1). Also, + there is a new data type for allocated color maps and routines to handle + it conveniently. +* Some minor bugs have been fixed. Most notably, the DGif code now correctly + handles the possibility of more than one code block per extension record, + as per the GIF spec. It's not clear, however, that anyone ever has or + ever will use this feature for anything... + +New Tools and Options +--------------------- +* A brand new, ultra-spiffy tool `icon2gif' is included. It assembles named + GIFs with editable text color map & icon raster representations to produce + multi-image GIFs usable as graphical resource files. It can also dump most + GIFs in the same text-only form it parses. This makes it easy to edit GIFs + even if you don't have a graphics editor. +* The gifclip utility supports a new `-c' (complement) option that allows you + to perform an `inverse clip', removing horizontal or vertical bands from an + image. +* The gifclrmp utility supports a new `-t' switch for shuffling color index + values. +* A new tool `gifcolor' generates test pattern from colormap input. + +New Documentation and Examples +------------------------------ +* The documentation has been overhauled completely and translated out of the + dialect spoken by the estimable Mr. Elber into something like standard + English :-). +* Two source code files gifspnge.c and giffiltr.c have been added to the + util directory. These are GIF copiers that exercise the I/O routines, + provided as skeletons for your applications. Read the comments in them + for more info. +* The util Makefile for UNIX has been improved. It now uses the cc/gcc -s + option rather than strip(1). There are now separate install productions, + so you can test new versions in util before installation for production + (the top-level make script still does an install). + +Version 1.2 +=========== +* GIFFIX - a new tool to attempt and fix broken GIF images.

grab the parameters from the command line: + +Names of all the routines except the main one start with GA (Get +Arguments) to prevent conflicts. + +The following routines are available in this module: + +1. int GAGetArgs(argc, argv, CtrlStr, Variables...) +where argc, argv are received on entry. +CtrlStr is the contrl string (see below) +Variables are all the variables to be set according to CtrlStr. +Note that all the variables MUST be transfered by address. +Return 0 on correct parsing, otherwise error number (see GetArg.h). + +2. GAPrintHowTo(CtrlStr) +Print the control string to stderr, in the correct format. +This feature is very useful in case of an error during GetArgs parsing. +Chars equal to SPACE_CHAR are not printed (regular spaces are NOT +allowed, and so using SPACE_CHAR you can create space in PrintHowTo). + +3. GAPrintErrMsg(Error) +Describe the error to stderr, according to Error (usually returned by +GAGetArgs). + +CtrlStr format: + +The control string passed to GetArgs controls the way argv (argc) are +parsed. Each entry in this string must not have any spaces in it. The +First Entry is the name of the program, which is usually ignored except +when GAPrintHowTo is called. All the other entries (except the last one +which we will come back to later) must have the following format: + +1. One letter which sets the option letter. +2. '!' or '%' to determines if this option is really optional ('%') or + required ('!')... +3. '-' must always be given. +4. Alphanumeric string, usually ignored, but used by GAPrintHowTo to + print the meaning of this option. +5. Sequences starts with '!' or '%'. Again if '!' then this sequence + must exist (only if its option flag is given of course), and if '%' + it is optional. Each sequence will continue with one or two + characters which defines the kind of the input: +a: d, x, o, u - integer is expected (decimal, hex, octal base or unsigned). +b: D, X, O, U - long integer is expected (same as above). +c: f - float number is expected. +d: F - double number is expected. +e: s - string is expected. +f: *? - any number of '?' kind (d, x, o, u, D, X, O, U, f, F, s) + will match this one. If '?' is numeric, it scans until + non-numeric input is given. If '?' is 's' then it scans + up to the next option or end of argv. + +If the last parameter given in the CtrlStr, is not an option (i.e. the +second char is not in ['!', '%'] and the third one is not '-'), all what +remained from argv is linked to it. + +The variables passed to GAGetArgs (starting from 4th parameter) MUST +match the order of the CtrlStr: + +For each option, one integer address must be passed. This integer must +be initialized with 0. If that option is given in the command line, it will +be set. + +In addition, the sequences that might follow an option require the +following parameters to pass: + +1. d, x, o, u - pointer to integer (int *). +2. D, X, O, U - pointer to long (long *). +3. f - pointer to float (float *). +4. F - pointer to double (double *). +5. s - pointer to char (char *). NO allocation is needed! +6. *? - TWO variables are passed for each wild request. the first + one is (address of) integer, and it will return number of + parameters actually matched this sequence, and the second + one is a pointer to pointer to ? (? **), and will return an + address to a block of pointers to ? kind, terminated with + NULL pointer. NO pre-allocation is required. + +Note that these two variables are pretty like the argv/argc pair... + +Examples: + +"Example1 i%-OneInteger!d s%-Strings!*s j%- k!-Float!f Files" + +Will match: Example1 -i 77 -s String1 String2 String3 -k 88.2 File1 File2 +or: Example1 -s String1 -k 88.3 -i 999 -j +but not: Example1 -i 77 78 (option i expects one integer, k must be). + +Note the option k must exist, and that the order of the options is not +important. In the first examples File1 & File2 will match the Files +in the command line. + +A call to GAPrintHowTo with this CtrlStr will print to stderr: +Example1 [-i OneIngeter] [-s Strings...] [-j] -k Float Files... + +Notes: + +1.

It was described +by a GIF standard issued in 1987 and revised in 1989. A copy of the +GIF89 standard is included in the doc/ directory. + +This code originated as a linkable library for DOS programs, together +with command-line tools for generating and viewing and analyzing GIF +images. The DOS code was written by Gershon Elber using Borland C +under MS-DOS sometime between the issue of GIF87 and mid-1989 (1.0 was +dated 14 June 1989; one portion, getarg.c, was dated 11 Mar 88). + +At some time no later than the end of 1989 Eric S. Raymond (aka "ESR") +ported this DOS version to System V Unix. Between 1989 and 1992 ESR +reworked various portions of the API, improving and simplifying +the code's interface. + +ESR's 2.1 version was the first to include the DGifSlurp()/EGifSpew() +function pair for enabling non-sequential operations on GIF images +(also the tools icon2gif, gifovly, and gifcompose; the last was +removed in 5.0). + +ESR's Unix port was incorporated into the NCSA/Netscape browser in +1994, which is how GIF became (with JPEG) one of the two most popular +image formats on the early Web. + +Beginning around 1993, patent claims by Unisys over the LZW +compression method used in GIF theatened adverse legal consequences +for users and developers of programs incorporating the format. The +threats became serious in 1999, with Unisys demanding license fees +for any software using the format. + +One response to this was the development of PNG in 1995. Another was +that ESR sought a lead developer outside the U.S. to hand the project off +to, and passed it to Toshio Kuratomi. ESR remembers this as happening +in 1994, but that date could be wrong as some headers imply 3.0 was issued +under ESR's name in 1996. But other files do date Toshio's first release +to 1994. Toshio shipped 4.0 in December 1998. + +Subsequently, the project shipped for some time as "libungif" with +support for compressed GIFs removed to avoid the LZW patent issues. +Compression support was merged back in after the last blocking patent +expired in 2004; this became release 4.0.0. After that merge the +code was again known as giflib. + +By 2006, support for PNGs was sufficiently universal that GIF could be +described as a legacy format. Anything you can do with it GIF could +probably be better done with PNG. Nevertheless (and despite efforts +like "Burn All GIFs Day" in November 1999) the GIF format has remained +widely popular. + +In April 2012 ESR rejoined the project to do some code cleanups +and auditing, and Toshio Kuratomi asked him to take back the lead. +ESR released version 4.2 in May 2012. + +Version 5.0, released in June 2012, fulfilled almost all the to-do +items from 18 years of backlog. It made the library thread-safe, added +direct support for GIF89 graphics control blocks, and tossed out large +amounts of obsolete utility code. + +This code is very old, very stable, and *everywhere* - browsers +game consoles, smartphones, pretty much everything that opens an +HTTP port and does graphics uses it. + +The utilities in this source tree were important as GIF production +tools early in the format's history, but have been superseded by +multi-format viewers and editors. Most installable binary packages +shipped as 'giflib' include the library and header file only. diff -Nru giflib-4.1.6/INSTALL giflib-5.0.5-2/INSTALL --- giflib-4.1.6/INSTALL 2007-11-10 22:53:34.000000000 +0000 +++ giflib-5.0.5-2/INSTALL 1970-01-01 00:00:00.000000000 +0000 @@ -1,234 +0,0 @@ -Installation Instructions -************************* - -Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005, -2006 Free Software Foundation, Inc. - -This file is free documentation; the Free Software Foundation gives -unlimited permission to copy, distribute and modify it. - -Basic Installation -================== - -Briefly, the shell commands `./configure; make; make install' should -configure, build, and install this package. The following -more-detailed instructions are generic; see the `README' file for -instructions specific to this package. - - The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation. It uses -those values to create a `Makefile' in each directory of the package. -It may also create one or more `.h' files containing system-dependent -definitions. Finally, it creates a shell script `config.status' that -you can run in the future to recreate the current configuration, and a -file `config.log' containing compiler output (useful mainly for -debugging `configure'). - - It can also use an optional file (typically called `config.cache' -and enabled with `--cache-file=config.cache' or simply `-C') that saves -the results of its tests to speed up reconfiguring. Caching is -disabled by default to prevent problems with accidental use of stale -cache files. - - If you need to do unusual things to compile the package, please try -to figure out how `configure' could check whether to do them, and mail -diffs or instructions to the address given in the `README' so they can -be considered for the next release. If you are using the cache, and at -some point `config.cache' contains results you don't want to keep, you -may remove or edit it. - - The file `configure.ac' (or `configure.in') is used to create -`configure' by a program called `autoconf'. You need `configure.ac' if -you want to change it or regenerate `configure' using a newer version -of `autoconf'. - -The simplest way to compile this package is: - - 1. `cd' to the directory containing the package's source code and type - `./configure' to configure the package for your system. - - Running `configure' might take a while. While running, it prints - some messages telling which features it is checking for. - - 2. Type `make' to compile the package. - - 3. Optionally, type `make check' to run any self-tests that come with - the package. - - 4. Type `make install' to install the programs and any data files and - documentation. - - 5. You can remove the program binaries and object files from the - source code directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile the package for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the package's developers. If you use it, you may have to get - all sorts of other programs in order to regenerate files that came - with the distribution. - -Compilers and Options -===================== - -Some systems require unusual options for compilation or linking that the -`configure' script does not know about. Run `./configure --help' for -details on some of the pertinent environment variables. - - You can give `configure' initial values for configuration parameters -by setting variables in the command line or in the environment. Here -is an example: - - ./configure CC=c99 CFLAGS=-g LIBS=-lposix - - *Note Defining Variables::, for more details. - -Compiling For Multiple Architectures -==================================== - -You can compile the package for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you can use GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. - - With a non-GNU `make', it is safer to compile the package for one -architecture at a time in the source code directory. After you have -installed the package for one architecture, use `make distclean' before -reconfiguring for another architecture. - -Installation Names -================== - -By default, `make install' installs the package's commands under -`/usr/local/bin', include files under `/usr/local/include', etc. You -can specify an installation prefix other than `/usr/local' by giving -`configure' the option `--prefix=PREFIX'. - - You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If you -pass the option `--exec-prefix=PREFIX' to `configure', the package uses -PREFIX as the prefix for installing programs and libraries. -Documentation and other data files still use the regular prefix. - - In addition, if you use an unusual directory layout you can give -options like `--bindir=DIR' to specify different values for particular -kinds of files. Run `configure --help' for a list of the directories -you can set and what kinds of files go in them. - - If the package supports it, you can cause programs to be installed -with an extra prefix or suffix on their names by giving `configure' the -option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. - -Optional Features -================= - -Some packages pay attention to `--enable-FEATURE' options to -`configure', where FEATURE indicates an optional part of the package. -They may also pay attention to `--with-PACKAGE' options, where PACKAGE -is something like `gnu-as' or `x' (for the X Window System). The -`README' should mention any `--enable-' and `--with-' options that the -package recognizes. - - For packages that use the X Window System, `configure' can usually -find the X include and library files automatically, but if it doesn't, -you can use the `configure' options `--x-includes=DIR' and -`--x-libraries=DIR' to specify their locations. - -Specifying the System Type -========================== - -There may be some features `configure' cannot figure out automatically, -but needs to determine by the type of machine the package will run on. -Usually, assuming the package is built to be run on the _same_ -architectures, `configure' can figure that out, but if it prints a -message saying it cannot guess the machine type, give it the -`--build=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name which has the form: - - CPU-COMPANY-SYSTEM - -where SYSTEM can have one of these forms: - - OS KERNEL-OS - - See the file `config.sub' for the possible values of each field. If -`config.sub' isn't included in this package, then this package doesn't -need to know the machine type. - - If you are _building_ compiler tools for cross-compiling, you should -use the option `--target=TYPE' to select the type of system they will -produce code for. - - If you want to _use_ a cross compiler, that generates code for a -platform different from the build platform, you should specify the -"host" platform (i.e., that on which the generated programs will -eventually be run) with `--host=TYPE'. - -Sharing Defaults -================ - -If you want to set default values for `configure' scripts to share, you -can create a site shell script called `config.site' that gives default -values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: not all `configure' scripts look for a site script. - -Defining Variables -================== - -Variables not defined in a site shell script can be set in the -environment passed to `configure'. However, some packages may run -configure again during the build, and the customized values of these -variables may be lost. In order to avoid this problem, you should set -them in the `configure' command line, using `VAR=value'. For example: - - ./configure CC=/usr/local2/bin/gcc - -causes the specified `gcc' to be used as the C compiler (unless it is -overridden in the site shell script). - -Unfortunately, this technique does not work for `CONFIG_SHELL' due to -an Autoconf bug. Until the bug is fixed you can use this workaround: - - CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash - -`configure' Invocation -====================== - -`configure' recognizes the following options to control how it operates. - -`--help' -`-h' - Print a summary of the options to `configure', and exit. - -`--version' -`-V' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`--cache-file=FILE' - Enable the cache: use and save the results of the tests in FILE, - traditionally `config.cache'. FILE defaults to `/dev/null' to - disable caching. - -`--config-cache' -`-C' - Alias for `--cache-file=config.cache'. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. To - suppress all normal output, redirect it to `/dev/null' (any error - messages will still be shown). - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`configure' also accepts some other, not widely useful, options. Run -`configure --help' for more details. - diff -Nru giflib-4.1.6/install-sh giflib-5.0.5-2/install-sh --- giflib-4.1.6/install-sh 2007-11-10 22:53:34.000000000 +0000 +++ giflib-5.0.5-2/install-sh 1970-01-01 00:00:00.000000000 +0000 @@ -1,507 +0,0 @@ -#!/bin/sh -# install - install a program, script, or datafile - -scriptversion=2006-10-14.15 - -# This originates from X11R5 (mit/util/scripts/install.sh), which was -# later released in X11R6 (xc/config/util/install.sh) with the -# following copyright and license. -# -# Copyright (C) 1994 X Consortium -# -# Permission is hereby granted, free of charge, to any person obtaining a copy -# of this software and associated documentation files (the "Software"), to -# deal in the Software without restriction, including without limitation the -# rights to use, copy, modify, merge, publish, distribute, sublicense, and/or -# sell copies of the Software, and to permit persons to whom the Software is -# furnished to do so, subject to the following conditions: -# -# The above copyright notice and this permission notice shall be included in -# all copies or substantial portions of the Software. -# -# THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR -# IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, -# FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

A few functions have been renamed. + +Code Fixes +---------- +* Fixes applied for CVE-2005-2974 and CVE-2005-3350 + This closes Debian bug #337972. + +New API Features +---------------- + +Thread Safety +~~~~~~~~~~~~~ +The library is now completely re-entrant and thread-safe. + +* Library error handling no longer uses a static cell to store the last + error code registered; that made the library thread-unsafe. For functions + other than GIF file openers, the code is now put in an Error member of + the GifFileType structure. The GifError() amd GifLastError() functions + that referenced that static cell are gone, and the GifErrorString() + function introduced in the 4.2 release now takes an explicit error code + argument. +* GIF file openers - DGifOpenFileName(), DGifOpenFileHandle(), DGifOpen(), + EGifOpenFileName(), EGifOpenFileHandle(), and EGifOpen() - all now take + a final integer address argument. If non-null, this is used to pass + back an error code when the function returns NULL. + +Extensions +~~~~~~~~~~ +The ExtensionBlock API has been repaired, solving some problems with GIF89 +extension handling in earlier versions. + +* DGifSlurp() and EGifSpew() now preserve trailing extension blocks with + no following image file. +* Three documented functions - EGifPutExtensionFirst(), EGifPutExtensionNext(), + and EGifPutExtensionLast() - have been relaced by new functions + EGifPutExtensionLeader(), EGifPutExtensionBlock(), and + EGifPutExtensionTrailer(). See the Compatibility section of + the library API documentation for details. +* New functions DGifSavedExtensionToGCB() and EGifGCBToSavedExtension() + make it easy to read and edit GIF89 graphics control blocks in saved images. + +Namespacing +~~~~~~~~~~~ +All functions exported by giflib now have DGif, EGif, or Gif as a name prefix. + +* Three documented functions - MakeMapObject(), FreeMapObject(), and + UnionColorMap() - have been renamed to GifMakeMapObject(), + GifFreeMapObject(), and GifUnionColorMap() respectively. +* The library Draw* functions are now prefixed GifDraw*, and the + text-drawing ones are suffixed with "8x8". This fixes a conflict + with the Windows API and leaves the door open for more general text-drawing + functions with different font sizes. + +Other changes +~~~~~~~~~~~~~ +* DGifSlurp() and EGifSpew() now read and write interlaced images properly. +* The amazingly obscure colormap sort flag and pixel aspect ratio + features of GIF are now read and preserved, for whatever good that + may do. +* Six undocumented functions have been renamed; five of these take additional + or slightly different argument types. See the Compatibility section of + the library API documentation for details. +* There's now an EGifGetGifVersion() that computes the version EGifSpew() + will write. +* QuantizeBuffer() has been returned to the core library as GifQuantizeBuffer() + - turns out some important applications (notably mplayer) were using it. +* TRUE and FALSE macros are gone, also VoidPtr. No more namespace pollution. +* Various arguments have been made const where possible. + +Retirements +----------- +* The (undocumented) gifinfo utility is gone. Use giftool -f instead. +* The gifburst utility is gone. Everybody has image viewers that + can pan now, and removing it gets rid of a dependency on Perl. +* gifcompose is gone. It was a decent idea when I wrote it in 1989, + but I did the same thing better and cleaner a decade later with + PILdriver in the PIL package. Removing it gets rid of a dependency + on shell. +* gif2x11 gifasm, gifcomb, gifflip, gifovly, gifpos, gifresize, and gifrotate + are all gone. The ImageMagick display(1)/convert(1) utilities and PILdriver + do these things better and in a format-independent way. +* Lennie Araki's Windows C++ wrapper is gone. It's eight years old, + unmaintained, he has dropped out of sight, and a better one needs to + be written to use the high-level GIFLIB API and GIF89 graphics + control extension support. We'll carry such a wrapper when we have + a maintainer for it. +* EGifSetVersion(), introduced in 4.2, is gone. The library always + writes GIF87 or GIF89 as required by the data. This change helps + with thread safety. + +Utilities +--------- +* Several utilities have been renamed to (a) fix last-century's habit + of arbitarily smashing vowels out of names to make them just one or two + characters shorter, (b) ensure that every utility in this set has 'gif' + as a name prefix. Here's the list: + + giffiltr -> giffilter + gifspnge -> gifsponge + icon2gif -> gifbuild + text2gif -> gifecho + raw2gif -> gif2raw + +* To go with its new name, gif2raw now dumps raw pixels from a GIF if the + (previously required) size option is missing. +* Standalone rgb2gif is gone; the same capability is now a mode of gif2rgb. +* giftext displays the parsed contents of GIF89 graphics control blocks. +* gifbuild handles GIF89 graphics control blocks and Netscape animation + loop blocks; it can can display and update either. +* gifrotate and other filter utilities now preserve extension blocks, + including the graphics control information for transparency and delay time. +* A new utility, giftool, supports a wide variety of filtering operations + on GIFs, including: setting background and transparency colors, changing + interlacing, setting image delays, setting the user-input flag, and setting + the aspect-ratio byte. It can sequence multiple operations. +* The test-pattern generators gifbg, gifcolor, gihisto and gifwedge and the + code templates giffilter and gifsponge are no longer installed by default. + +Documentation and polish +------------------------ +* The history.txt and build.txt and files from 4.2.0 now have .asc extensions + to indicate that they use asciidoc markup, contrasting with the txt + standards files from CompuServe. +* The documentation now includes "What's In A GIF", a very detailed narrative + description of the file format. +* The -A option of gifasm (for inserting a loop control block) is documented. +* The documentation directory includes a copy of the original GIF87 + specification as well as GIF89's. +* The project now has a logo. + +Version 4.2.0 +============= + +Now maintained by ESR again after handoff by Toshio Kuratomi. + +Code Fixes +---------- +* Code updated internally to C99 to enable more correctness checks by + the compiler. Compiles under GCC 4.6.1 without errors or warnings. +* A rare resource leak in the colormap-object maker was found with + Coverity and fixed. +* The code now audits clean under Coverity and cppcheck. +* splint cleanup begun, there's a lot of work still to do on this. + +New API Features +---------------- +* The default GIF version to write is now computed at write time from + the types of an image's extension blocks, but can be overridden with + EGifSetGifVersion(). +* EGifSpew() is now thread-safe. +* Two new functions, GifError() and GifErrorString(), + return the error state in a form that can be used by programs. +* Two library functions - EGifOpenFileName() and EGifPutImageDesc() - + now have bool rather than int flag arguments. Since bool is a + typedef of int and TRUE/FALSE have been redefined to true/false, + both source and object compatibility with older library versions + should be preserved. +* GAGetArgs(), used only in the utilities, now returns bool rather + than int. +* The undocumented GIF_LIB_VERSION symbol is gone from the library header. + It has been replaced with three documented symbols: GIFLIB_MAJOR, + GIFLIB_MINOR, and GIFLIB_RELEASE. + +Retirements +----------- +* The gif2epsn and gif2iris utilities are gone. They were full of + platform dependencies for platforms long dead. There are enough + platform-independent GIF viewers in the world that these weren't + adding any value. Removing these gets rid of a dependency on GL. +* The rle2gif, gif2rle, and gif2ps utilities are also gone. There are enough + multiformat image converters in the world that these weren't adding + any value either. Removing them reduces the codebase's dependencies. +* The undocumented DumpScreen2Gif() is gone from the library. The + only non-obsolete capture mode it supported was through X, and that + probably hasn't been used in years and is replaceable by any number + of capture utilities. Dropping this code makes the library's + portability issues go away. +* QuantizeBuffer(), GifQprintf(), PrintGifError(), GIF_ERROR() + and GIF_MESSAGE() have been removed from the core library. + They were used only by the utilities. QuantizeBuffer() has been + inlined where it was used and the latter three are now part of the + utility support library. +* The Game Boy Advanced test code is gone. The platform was discontinued + in 2008; more to the point, nobody ever documented the code's assumptions + or expected results. +* The Changelog file is now retained for archival purposes only, and because + autotools throws a hissy fit if there isn't one. The single point of + truth about changes and the reasons for them is the repository history. + +Behavior changes +---------------- +* The -q option of the utilities is replaced by an opposite -v (verbose) + option; the default is now quiet for all platforms. Defaulting to chattiness + on MSDOS made sense in a world of slow text consoles, but not today. + +Testing +------- +* There is now a proper regression-test suite; run 'make' in tests/. + The old test-unx script is now tests/visual-check and can be run + occasionally for a check with the Mark One Eyeball. + +Documentation +------------- +* Build instructions now live in build.txt +* An overview of the giflib API now lives in api.txt. +* Documentation is now in DocBook-XML, so either HTML or man pages can + be generated from it. + Version 4.1.6 ============= Brown paper bag release.

Extensions are "extensions" and -people may want to look for them grouped together.... I suppose this could -either mean leaving everything in the extension array, or creating a new -extension field that has the extensions dangling off of it (comment, gifanim -stuff, unknown, etc.) This is okay except that it'd be best to have real -copies of the extension in the fields instead of links (so that we could make -arrays rather than arrays of pointers.) - -[UPDATE:1998 3 Dec] -After reading through the gif89a specification, I'm not sure this is all that -great. It seems that each image in a gif stream needs to have separate -extension blocks. This means that an animated gif will have a Graphics -Extension Block for each Image in the animation.
