i.rgb.his -

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 map layers are created by a standard red-green-blue (rgb) to hue-intensity-saturation (his) color transformation. Each output map layer is given a linear grey scale color table.
