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.
