Depends on how much intelligence you put into your image format. I
wrote a program to convert from xpm to xbm which would do the color
conversions the way I wanted them. You draw the xpm and then you
specify conversions like this:
--
white gray50
None white
dodger blue white
blue black
firebrick black
goldenrod black
yellow gray75
sienna black
pale green black
chocolate white
--
The conversions then get taken through the ppmtopgm | pgmtopbm |
pbmtoxbm pipeline which produces quite usable pictures.
The program is available from madhatter.ws.cc.cmu.edu:pub/xpmtoxbm.pl,
and the stuff I drew as KhoiKhoi.tar.gz
