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 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

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.

       -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.
