       green=string [required]
           Name of raster map to be used for <green>

       blue=string [required]

DESCRIPTION

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

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

       To get the full area and resolutin of the raster map, run:
       g.region raster=[mapname]

       before running r.out.ppm3.

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.
