KEYWORDS

imagery, color transformation, RGB, HIS

SYNOPSIS

i.rgb.his
i.rgb.his help
i.rgb.his red_input=name green_input=name blue_input=name hue_output=name intensity_output=name saturation_output=name [--overwrite] [--verbose] [--quiet]

Flags:

--overwrite

Allow output files to overwrite existing files
--verbose

Verbose module output
--quiet

Quiet module output

Parameters:

red_input=name

Name of input raster map (red)
green_input=name

Name of input raster map (green)
blue_input=name

Name of input raster map (blue)
hue_output=name

Name for output raster map (hue)
intensity_output=name

Name for output raster map (intensity)
saturation_output=name

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.
