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
ppmdither -red 2 -green 2 -blue 2
OPTIONS¶
In addition to the options common to all programs based on
libnetpbm (most notably -quiet, see
Common Options ), ppmtopj recognizes the following command line
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.
