Well, not quite, just the format of REBOL bitmaps. (: I've not looked
at bmp formats, but I assume they might allow for alpha channels and
other stuff. If so, does this have any bearing on what REBOL expects
of a bmp?
Except I've found a problem with my suggestion above - there's no
save/png in Core. (At least not in the free version.) Which I think
means you're back to working out a gif, (or png? it's an open format,
so info should be widely available), routine of your own. Not such a
good idea afterall...
I take it bmp files would be too big for what you're doing with them?
