Ppmtopj User Manual(1) General Commands Manual Ppmtopj User Manual(1) 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.
