Sorry, I got carried away :) My point was that we either decide that GEGL should render just like legacy, in which case we would need to implement both kinds of color layer modes in GEGL, or we decide that some incompatibilities are OK, in which case we don't need the legacy color modes in GIMP. If we end up using the SVG 1.2 compositing model, we have decided we won't be compatible. But if we change to use our legacy compositing model in GEGL too, then for simplicity we should also make sure to render legacy files with GEGL like the legacy rendering engine does it, i.e. implement all layer modes. Right now, the Overlay layer mode actually renders differently in GEGL than in legacy, so we would also have to introduce an "(obsolete)" version of Overlay. (The legacy Overlay is exactly identical to legacy Soft Light, but the GEGL Overlay is different from the GEGL Soft Light.) / Martin -- My GIMP Blog: http://www.chromecode.com/ "Automatic tab style and removed tab title bar" _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
