r.out.ppm3 - Converts 3 GRASS raster layers (R,G,B) to a PPM image file.

       Glynn Clements
       Based upon r.out.ppm and d.rgb.

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.

r.out.ppm3  - Converts 3 GRASS raster layers (R,G,B) to a PPM image file.

       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.
