OK I understand. I see where you are coming from. Would we use the fRAc chunk for this? We need to define a few standards before we go in too deep.
I'm not sure if the contents of the fRAc chunk were ever defined. Tim, can you comment on that? You could always make an application-specific chunk. There is the possibility of chunk name clashes with other apps, so I think the libpng folks recommend registering chunks through them somehow. Its been a while since I looked at that, its probably in the libpng docs somewhere. -- Ask me about my upcoming book on Direct3D from Addison-Wesley!
