ppmtopj - convert a PPM image to an HP PaintJet file

       Copyright (C) 1991 by Christos Zoulas.

       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:

       -rle   Run length encode the image.  (This can result in larger images)

       -back  Enhance the foreground by  indicating  if  the  background  is  light  or  dark  compared  to  the
              foreground.

       -renderalg
              Use an internal rendering algorithm (default dither).

       -gammaint
              Gamma correct the image using the integer int as a gamma (default 0).

       -center
              Center the image to an 8.5 by 11 page

       -xpospos
              Move by pos pixels in the x direction.

       -ypospos
              Move by pos pixels in the y direction.
