I think introducing the conepts of "implicit profiles" > adds unnecessary complexity. If the user with a weird monitor (wide-gamut, AdobeRGB, or other) has a display profile and opens an image-without-profile, what do we display? We can't apply the display profile unless the image has some source color profile to link to the transform. Hence, we assume sRGB to enable this and other situations to behave as correctly as possible. The sRGB assumption is one what we already make, this change will simply make that assumption a bit more explicit. In doing so, it allows us to stop special-casing for cases where the image may not have a color profile. We gain uniformity of display logic and a decrease in code complexity by being able to assume the presence of a color profile as an invariant. And the code itself is trivial: just add a "give_me_color_profile" function which returns icc-profile contents if present, or the sRGB profile otherwise. (with a more-reasonable name, of course). --xsdg _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
