NAME
ppmtopj - convert a portable pixmap 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
Reads a portable pixmap 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 get this by
sending the input file through ppmquant -map with a map file
such as:
P3
8 1
255
0 0 0 255 0 0 0 255 0 0 0 255
255 255 0 255 0 255 0 255 255 255 255 255
Or else you could use use ppmdither -red 2 -green 2 -blue
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 integet
parameter 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.
