<h2>DESCRIPTION</h2>

<b>r.out.ppm3</b> converts 3 GRASS raster layers (R,G,B) to a PPM
image file, using the current region.

<p>This program converts a GRASS raster map to a PPM image file
using the the current region settings.

<p>To get the full area and resolutin of the raster map, run:

<div class="code"><pre>
g.region rast=[mapname]
</pre></div>

<p>before running <em>r.out.ppm3</em>.

<h2>NOTES</h2>

One pixel is written for each cell value, so if ew_res and ns_res
differ, the aspect ratio of the resulting image will be off.
