What are the resolution & colors for "Text" and "Photo" options in Simple Scan ?

In Lucid Xsane has been replaced by Simple Scan.

What are the resolution and color settings for Text and for Photo ? Perhaps having that information in the hover bubble would help.

I use GNOME Scan2PDF which is quite functional. You can install it by entering »sudo apt-get install gscan2pdf« in a terminal. Regarding the original part of your question I can't help.

@Aquina thank you, I am just wondering what the new simple-scan settings are. I know about scan2pdf and other similar tools.

Text is 200dpi, photo is 400dpi. They are hard-coded but bug #498046 is to put these settings in the preferences. I expect I'll have that fixed in 0.8.3.

I read the original question ("What are the resolution and color settings for Text and for Photo?") again and think I now realized what you really wanted to know.

- There is no *default* resolution or colour setting for text or image scanning. Hence every device works different and therefore applications allow us to adjust settings wherever possible and necessary to achieve the best result possible.

- You *can* set text to 200dpi (Personally I use 150dpi which is sufficient for my demands) and photo to 400dpi (Guess 300dpi for low-res photos and 600 high-quality is ok too).

- More important is the save-tab (if existant). Use a good compression method like jpeg or png with adjustable quality. When scanning an document (text only) I store the 150dpi scan as 85% quality jpg file which usually takes 200kB per page. I think that's sufficient for archiving.

When satisfied please mark this question as solved by selecting the answer that helped you the most. Thanks!
