--verbose

Verbose module output
--quiet

Quiet module output

Parameters:

red_input=name

Red input raster map
green_input=name

Green input raster map
blue_input=name

Blue input raster map
hue_output=name

Output hue raster map
intensity_output=name

DESCRIPTION

i.rgb.his is an image processing program that processes three input raster map layers as red, green, and blue components and produces three output raster map layers representing the hue, intensity, and saturation of the data. The output raster map layers are created by a standard red-green-blue (rgb) to hue-intensity-saturation (his) color transformation. Each output raster map layer is given a linear gray scale color table. The current geographic region definition and mask settings are respected.
