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.
