[net.micro.mac] How could you do Color on the Mac

keashly@winston.UUCP (Lance Keashly) (10/24/85)

This is something that has been nagging at me for awhile.
In "Inside Macintosh" they mention that the quickdraw routines can handle
color someday when the hardware can. My question is how would it do that?

The GrafPort definition has fgColor and bkColor and a strange thing called
colrbit. The way the book talks about the colrbit it sounds like the routines
are geared towards separate bitplanes. The ??Color fields though seem to
hint more at a multiple bit per pixel organization. Which way is it?

The BitMap definition has no field to tell how many bits per pixel, but
the GrafPort does not seem to have any way to define other BitMap bitplanes.

Plus if you look at the predefined Color values they look like arbitrary values
so I can't use them to make a guess.

Any help, discussion would be useful as I am very curious on how the software
could do color.

Thanks
