[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 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.
