NAME
ppmtopj - convert a PPM image 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
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.
