[ppmfile]
This program is part of Netpbm(1).
ppmtopj reads a PPM image as input and converts it into a format suitable to be printed by an HP PaintJet printer.
For best results, the input file should be in 8-color RGB form; i.e. it should have only the 8 binary combinations of full-on and full-off primaries. You could convert your input to this format like this:
pamseq 3 1 testimg.ppm >8color.pam
pnmremap -map 8color.pam testimg.pam | ppmtopj
Or you could use
ppmdither -red 2 -green 2 -blue 2
In addition to the options common to all programs based on libnetpbm
(most notably -quiet, see
Common Options
), ppmtopj recognizes the following
command line options:
HP PaintJet XL Color Graphics Printer User's Guide, pnmtopclxl(1), pjtoppm(1), pamdepth(1), pnmremap(1), pamseq(1), ppmdither(1), pbmtolj(1), ppmtolj(1), ppmtopjxl(1), thinkjettopbm(1), ppm(1)
