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 current region settings.
To get the full area and resolution 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.
