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