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? -- Carl Read
