ppmtopj reads a PPM image as input and converts it into a
|
|
Packit |
78deda |
format suitable to be printed by an HP PaintJet printer.
|
|
Packit |
78deda |
|
|
Packit |

|
|

For best results, the input file should be in 8-color RGB form;
|
|
Packit |
78deda |
i.e. it should have only
|
|
Packit |
78deda |
the 8 binary combinations of full-on and full-off primaries.
|
|
Packit |
78deda |
You could convert your input to this format like this:
|
|
Packit |
78deda |
|
|
Packit |
78deda |
|
|
Packit |
78deda |
pamseq 3 1 testimg.ppm >8color.pam
|
|
Packit |
78deda |
pnmremap -map 8color.pam testimg.pam | ppmtopj
|
|
Packit |
78deda |
|
|
Packit |
78deda |
|
|
Packit |

Or you could use
|
|
Packit |

|
|
