DESCRIPTION

47       r.rgb generates separate red, green and blue maps from a raster map and
48       its associated color table (grey255).
49

EXAMPLE

51       g.region raster=elevation -p
52       r.rgb input=elevation red=elevation.r green=elevation.g blue=elevation.b
53
54       In this case r.rgb produces in the current mapset three new raster maps
55       - ’elevation.r’, ’elevation.g’, ’elevation.b’.
