NAME

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

KEYWORDS

imagery

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 [--overwrite]

Flags:

--overwrite
Force overwrite of output files

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.
