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 }]



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


-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 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.
