Are there any open source sprite format?

PNG just plainly sucks. I has no support for animations, timing or delta compression and sequence names. Also, PNG is slow at random access (you have to decompress image before use). Proprietary formats (like Diablo 2 DCC) are much better, but highly specialized for their games: some have no true color, other have no directions.

This thread is painful to read. This is the problem with ``Software Engineering'' and seemingly simple things: a lot of imbeciles who have no clue of what they're talking about think spouting their misinformed opinions is a good idea.
