DESCRIPTION

48       r.out.ppm3  converts 3 GRASS raster layers (R,G,B) to a PPM image file,
49       using the current region.
50
51       This program converts a GRASS raster map to a PPM image file using  the
52       the current region settings.
53
54       To get the full area and resolutin of the raster map, run:
55       g.region raster=[mapname]
56
57       before running r.out.ppm3.

NOTES

60       One  pixel is written for each cell value, so if ew_res and ns_res dif‐
61       fer, the aspect ratio of the resulting image will be off.
