over 2 years agoSolution to this is to re-encode into png before editing jpeg with tools like GraphicsMagick, ImageMagick or proprietary xnview. You don't need this to do for jpegs created with GIMP.
You can test it yourself, type in terminal:
#for graphicsmagick
gm compare scan.jpg scan_exported_from_gimp.png -file diff.png
gm compare -metric mae scan.jpg scan_exported_from_gimp.png
#for imagemagick
compare -metric mae scan.jpg scan_exported_from_ps.png diff.png
Fixed with GIMP. Enjoy.
