Hi Right now we don't have a clearly defined color management strategy for GIMP. I would like us to settle a minimal color management strategy for GIMP so that we can fix some inconsistencies in our color management, in particular for PNG [1], for 2.8. In short the problem with PNG is that the current code always writes an sRGB chunk to a PNG file if no color profile is attached to the image and no gamma is specified. I suggest that we formally settle with this minimal color management strategy: """ An image either has or has not a color profile attached. A color profile is attached as a GimpParasite named "icc-profile". For images that have a color profile attached, this color profile is used when displaying the image and is embedded when the image is saved or exported. For images that does not have a color profile attached, the global color profile defined under Color Management in Preferences is used to display the image, but no profile is embedded into saved or exported files. """ So, does the above sound like a sound foundation for color management in GIMP? I don't expect us to have time to apply this strategy consistently all over GIMP for 2.8 but at least we have settled on something that we can put in devel-docs and continue to build on later, and it allows us to fix the PNG problem for 2.8. / Martin [1] PNG output: omit unwanted chunks (sRGB) https://bugzilla.gnome.org/show_bug.cgi?id=599065 -- My GIMP Blog: http://www.chromecode.com/ "Best way to keep up with GIMP from git" _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
