NAME

       r.out.ppm3   -  Converts  3  GRASS  raster layers (R,G,B) to a PPM image file at the pixel
       resolution of the CURRENTLY DEFINED REGION.

KEYWORDS

       raster, export

SYNOPSIS

       r.out.ppm3
       r.out.ppm3 help
       r.out.ppm3 [-qc] red=string green=string blue=string output=string  [--verbose]  [--quiet]

       --verbose
           Verbose module output

       --quiet
           Quiet module output

   Parameters:
       red=string
           Name of raster map to be used for

       green=string
           Name of raster map to be used for

       blue=string

       output=string
           Name for new PPM file. (use out=- for stdout)

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 rast=[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.
