DESCRIPTION

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.
