SYNOPSIS
ppmtopj [-gamma val] [-xpos val] [-ypos val] [-back dark|lite] [-rle] [-center] [-render mode] [ppmfile]
DESCRIPTION
ppmtopj reads a PPM image and converts it to HP PaintJet printer format for direct printing. For best results, the input should be in 8-color RGB form (binary combinations of full-on and full-off primaries). Part of the Netpbm toolkit.
PARAMETERS
-gamma val
Gamma correction value (default 0).-xpos val
Move by val pixels in the x direction.-ypos val
Move by val pixels in the y direction.-back dark|lite
Enhance foreground by indicating if background is light or dark.-rle
Run-length encode the image (may result in larger images).-center
Center the image on an 8.5 by 11 page.-render mode
Internal rendering algorithm: none, snap, bw, dither (default), diffuse, monodither, monodiffuse, clusterdither, monoclusterdither.
