27 Reads a portable pixmap as input and converts it into a
2 perry 28 format suitable to be printed by an HP !PaintJet
1 perry 29 printer.

32 For best results, the input file should be in 8-color RGB
33 form; i.e. it should have only the 8 binary combinations of
34 full-on and full-off primaries. You could get this by
35 sending the input file through ''ppmquant -map'' with a
36 map file such as:

39 P3
40 8 1
41 255
42 0 0 0 255 0 0 0 255 0 0 0 255
43 255 255 0 255 0 255 0 255 255 255 255 255
44 Or else you could use use ''ppmdither -red 2 -green 2 -blue 2.''
