<H2>DESCRIPTION</H2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<P><b>ppmtopj</b> reads a PPM image 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 convert your input to this format like this:
<pre>
pamseq 3 1 testimg.ppm >8color.pam
pnmremap -map 8color.pam testimg.pam | ppmtopj
</pre>
Or you could use use
<pre>
ppmdither -red 2 -green 2 -blue 2
</pre>

<H2>OPTIONS</H2>
<DL COMPACT>
<DT><B>-rle</B>
<DD>
Run length encode the image.
(This can result in larger images)
<DT><B>-back</B>
<DD>
Enhance the foreground by indicating if the background is light or
dark compared to the foreground.
<DT><B>-render</B> <I>alg</I>
<DD>
Use an internal rendering algorithm (default dither).
<DT><B>-gamma</B> <I>int</I>
<DD>
Gamma correct the image using the integer <i>int</i> as a gamma (default 0).
<DT><B>-center</B>
<DD>
Center the image to an 8.5 by 11 page
<DT><B>-xpos</B> <I>pos</I>
<DD>
Move by <i>pos</i> pixels in the x direction.
<DT><B>-ypos</B> <I>pos</I>
