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

r.out.ppm3 [-c] red=string green=string blue=string output=string [--verbose] [--quiet] [--qq] [--ui]

Example:

r.out.ppm3 red=string green=string blue=string output=string

grass.script.run_command("r.out.ppm3", red, green, blue, output, flags=None, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("r.out.ppm3", red="string", green="string", blue="string", output="string")

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 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.
