Because you are using JPEG despite better knowledge that it will do exactly that. Sorry for the harsh tone, but I am only replying the way you are putting it. Sven, I do think you're being unreasonably hard on Guillermo. Never mind that using JPEG per se won't "do exactly that" -- what's really degrading the quality so badly is GIMP's choice of a quality factor compared to that of the original JPEG. Not to mention that I think Guillermo is being quite reasonable. A lot of people (particularly folks who just casually want to lighten a shot or remove redeye) don't know it. All they know is that they have a picture that their camera took, they've corrected it, and all of a sudden the image quality fell apart. They don't know anything about JPEG's, or compression (lossy or otherwise), all they know is that GIMP ruined their photo. That's not going to be very helpful to anyone. I already explained that the JPEG plug-in cannot access the settings that were used to save the file. We can also not easily change the code to always show the settings dialog because then we would have to do show the dialog for all file plug-ins. There might be a way out of this, but there is certainly not an easy one. So please calm down and let the developers deal with this. After all this is a developer list. Your harsh comments are not helpful. Well, as was noted ImageMagick is able to access this information, so it's apparently there. Maybe this isn't going to be an easy problem to solve, and that's OK, but I think that this is a real problem, not simply a user error (and even if it is a user error, wouldn't it be best to help users not make this kind of error?). -- Robert Krawitz <rlk@xxxxxxxxxxxx> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf@xxxxxxxxxxxx Project lead for Gutenprint -- http://gimp-print.sourceforge.net "Linux doesn't dictate how I work, I dictate how Linux works." --Eric Crampton _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
