NAME
       ppmtopj - convert a PPM image to an HP PaintJet file


SYNOPSIS
       ppmtopj

       [-gamma val]

       [-xpos val]

       [-ypos val]

       [-back {dark|lite}]

       [-rle]

       [-center]

       [-render  {  none | snap | bw | dither | diffuse | monodither | monodiffuse | clusterdither | monoclusterdither
       }]

       [ppmfile]


DESCRIPTION
       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 combina-
       tions 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 use
           ppmdither -red 2 -green 2 -blue 2


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 compated to the foreground.


       -render alg
              Use an internal rendering algorithm (default dither).


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


       -center
              Center the image to an 8.5 by 11 page


       -xpos pos
              Move by pos pixels in the x direction.


       -ypos pos
              Move by pos pixels in the y direction.
