NAME

       i.rgb.his     -    Transforms    raster   maps   from   RGB   (Red-Green-Blue)   color   space   to   HIS
       (Hue-Intensity-Saturation) color space.

KEYWORDS

       imagery, color transformation, RGB, HIS, IHS

   Parameters:
       red=name [required]
           Name of input raster map (red)

       green=name [required]
           Name of input raster map (green)

       blue=name [required]
           Name of input raster map (blue)

       hue=name [required]
           Name for output raster map (hue)

       intensity=name [required]
           Name for output raster map (intensity)

       saturation=name [required]
           Name for output raster map (saturation)

DESCRIPTION

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