<H2>DESCRIPTION</H2>
|
|
|
|
Reads a portable pixmap as input and converts it into a format suitable
|
|
to be printed by an HP PaintJet printer.
|
|
<P>
|
|
|
|
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
|
|
<I>ppmquant -map</I>
|
|
|
|
with a map file such as:
|
|
