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.
