NAME

ppmtopj - convert a portable pixmap 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

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 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.
