NAME

i.rgb.his - Red-green-blue (rgb) to hue-intensity-saturation (his) raster map color transformation function.

SYNOPSIS

i.rgb.his

i.rgb.his help

i.rgb.his red_input=string green_input=string blue_input=string hue_output=string intensity_output=string saturation_output=string

Parameters:

"red_input=string
input map representing the red
"green_input=string
input map representing the green
"blue_input=string
input map representing the blue
"hue_output=string
output hue map name
"intensity_output=string
output intensity map name
"saturation_output=string
output saturation map name

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.
