.SH DESCRIPTION
\fBr.out.ppm3\fR converts 3 GRASS raster layers (R,G,B) to a PPM
image file, using the current region.
.PP
This program converts a GRASS raster map to a PPM image file
using the the current region settings.
.PP
To get the full area and resolutin of the raster map, run:
.br
.nf
\fC
g.region raster=[mapname]
\fR
.fi
.PP
before running \fIr.out.ppm3\fR.
.SH NOTES
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.
