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

SYNOPSIS

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

Flags:

-q

Run quietly

-c

Add comments to describe the region

--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

Name of raster map to be used for

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.
