Hi folks!

   I'm starting to play with my HP PaintJet.  If someone from HP can
help, that would be real nice.  I was wondering, what is the significance
of the range of the RGB palette values (R 2-90, G 4-88, B 6-85)?  If my
program reads in 3 8-bit values per pixel (for RGB) should I scale and
offset them from 0-255 --> 4-90 (with the red color for example)  or just
give the PJ the full 0-255 and let it take care of any conversion to its
NTSC color mapping?

   Thanks for your help!!!
