I was told that at the last DevCon, C-A officially adopted ASDG's 24-bitplane IFF format (they worked together to iron out the specifics). > I'm thinking of defining an alternate to ILBM chunks which > allow non-bitplane interleaved image storage (like perhaps line interleaved > instead). That's called "chunky" bitmaps, and it's usually done on a per-pixel basis. It is *much* easier for a program to work with if one is doing internal calculations. At DevCon, C-A officially adopted a chunky bitmap IFF spec (which was co-developed by ASDG & C-A) (DISCLAIMER: I'm not associated with ASDG or C-A and I wasn't at DevCon, but this is what I recall from some net (and non-net) summaries of the last DevCon. I'm sure I'll be flameboyantly corrected for any discrepancies :-)) -- Drew University -- Tom Limoncelli C M Box 1060 -- limonce@pilot.njin.net limonce@pilot.rutgers.edu P O Box 802 -- tlimonce@drunivac.Bitnet <<<-has a "T" in it.
