That's unfortunate. > If you send a patch, I'll review/merge it into the > Debian package. Since I know little or nothing about JPEG compression and stuff like that, I am afraid that it would take ages to me before I can figure out where's the actual bug and how to fix it... :-( By performing some tests, I noticed that the problem seems to cause that a thin rectangle of the image gets moved from one side to the other (e.g. from bottom to top or from left to right or the other way around) and mirrored. For instance: $ wget http://i999.photobucket.com/albums/af115/vampire_and_anime_cool_and_sexy/db12.jpg $ exiftran -p -9 -i db12.jpg This clearly shows that a thin rectangle that was at the bottom of the image, gets moved to the right side (rather than to the left side, as it should) and is mirrored. I hope this hint may help in pinpointing the bug. -- http://www.inventati.org/frx/progs/scripts/pdebuild-hooks.html Need some pdebuild hook scripts? .....................................................
