ppmtopj — convert a PPM image to an HP PaintJet file



[-gamma val]

[-xpos val]

[-ypos val]

[-back {dark|lite}]



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



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


Run length encode the image. (This can result in larger images)
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 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.
