Of course it is to some extent. Your going to have a really hard time
compressing random pixels, say, whatever you do. If there are a variety
of tools that work in different circumstances, I'd like to hear about
them.
If any of it works better producing PNGs, or GIFs, or even XBMs
(unlikely) I'd like to hear about that, too.
