ppmtolj - convert a portable pixmap to an HP LaserJet PCL 5 Color file
SYNOPSIS
ppmtolj [-gamma val] [-resolution 75|100|150|300|600] [-delta] [-float] [-noreset] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input and converts it into a color file suitable to be printed by an HP color PCL 5 printer.
OPTIONS -delta Apply delta row compression to reduce the size of the pcl file.
-gamma int Gamma correct the image using the integet parameter as a gamma (default 0).
-float Suppresses positioning information. The default is to write the sequence ESC&l0E to the output.
-noreset Prevents writing of the reset sequence to the begining and end of the output.
-resolution Set the required output resolution 75|100|150|300|600

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|monodif-
fuse|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 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 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.
