54 i.rgb.his is an image processing program that processes three input
55 raster map layers as red, green, and blue components and produces three
56 output raster map layers representing the hue, intensity, and satura‐
57 tion of the data. The output raster map layers are created by a stan‐
58 dard red-green-blue (RGB) to hue-intensity-saturation (HIS) color
59 transformation. Each output raster map layer is given a linear gray
60 scale color table. The current geographic region definition and mask
61 settings are respected.
