Maybe we should just tell these people that we feel the same way about XCF as JASC do about PSP, Adobe do about PSD. If we wake up and decide to invert the meaning of 50% of flags, re-arrange the structures and then add fourteen mysterious new values that's OUR problem, and trying to "standardise" our private format makes no sense. There is a mostly completed, free/open standard for storing lots of related image data called MNG. It was primarily targetted at animation but the higher levels include IMHO sufficient expressiveness to store image layer stacks, icon collections or any other type of multi-image format. http://www.libpng.org/pub/mng/ With a few public "required" chunks added you could express any image layer stack in this format and no-one loses their private format for future expansion (which is the harsh reality of what will happen if we support these plans to implement XCF in other apps) Nick.
