Ghostscript release 1.3 will definitely include the ability to obtain
bitmap output.  It will definitely support monochrome, using a fixed
bit ordering (big-endian) and polarity (0=black, 1=white) -- the
program that writes out the results can easily flip the bit order or
reverse the polarity by table lookup if it wants to.  With a modest
amount of work I can make Ghostscript support 8-bit gray scale or
mapped color (*you* supply the map -- note that by supplying an
appropriate map, you can get true color as long as combined widths of
the R, G, and B don't exceed 8 bits).  With equally modest work I can
make it support 32-bit true color (8 bits each R, G, B, and unused).
With somewhat more work I could implement more of the color options
that are offered by, for example, X Windows, but I'd rather not.

I'd like to hear opinions about which of these options would be most
valuable.

	Thanks -
