PROGRAM:

NAME

r3.colors - Creates/modifies the color table associated with a 3D raster map.

KEYWORDS

raster3d, color table

SYNOPSIS

--help
Print usage summary

--verbose
Verbose module output

--quiet
Quiet module output

--ui
Force launching GUI dialog

Parameters:
map=name[,name,...]
Name of 3D raster map(s)

file=name
Input file with one map name per line
Input map names can be defined in an input file in case a large amount of maps must be
specified. This option is mutual exclusive to the map option.

"-" to read rules from stdin

DESCRIPTION

r3.colors has exactly the same functionality as r.colors but for 3D raster maps. Please
refer to r.colors.

EXAMPLES

r3.colors map=volume_1 color=gyr
