## 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.
