DESCRIPTION

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