jpegexiforient does nothing in bionic

Asked by Steve Stevenson on 2018-12-29

It seems this program isn't operative in Ubuntu 18.04, unless I've overlooked something.

$ md5sum parrots.jpg
1b624b6d36f1c47f17095ae3dd336a92 parrots.jpg
$ jpegexiforient -2 parrots.jpg
$ echo $?
0
$ md5sum parrots.jpg
1b624b6d36f1c47f17095ae3dd336a92 parrots.jpg
$ jpegexiforient -9 parrots.jpg
jpegexiforient reads or writes the Exif Orientation Tag in a JPEG Exif file.
Usage: jpegexiforient [switches] jpegfile
Switches:
  --help display this help and exit
  --version output version information and exit
  -n Do not output the trailing newline
  -1 .. -8 Set orientation value 1 .. 8
$ echo $?
1
$ jpegexiforient -3 parrots.jpg
$ echo $?
0
$ md5sum parrots.jpg
1b624b6d36f1c47f17095ae3dd336a92 parrots.jpg

Visually confirmed that the image does not display any differently after the failed EXIF changes (which would have been an interesting result considering the hash of the file stayed constant).

I downloaded a sample JPEG file from the following location ("PARROTS") https://www.fileformat.info/format/jpeg/sample/
