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 | monodif-
fuse | clusterdither | monoclusterdither }]
[ppmfile]
DESCRIPTION
This program is part of Netpbm(1).
ppmtopj reads a PPM image as input and converts it into a format suit-
able 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 pri-
maries. 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 ⟨index.html#commonoptions⟩ ), 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 (de-
fault 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.
