DESCRIPTION

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.
