i.rgb.his(1)		    GRASS GIS User's Manual		  i.rgb.his(1)

NAME
       i.rgb.his   -  Transforms  raster  maps from RGB	(Red-Green-Blue) color
       space to	HIS (Hue-Intensity-Saturation) color space.

KEYWORDS
       imagery,	color transformation, RGB, HIS,	IHS

SYNOPSIS
       i.rgb.his
       i.rgb.his --help
       i.rgb.his red=name green=name blue=name hue=name	intensity=name satura-
       tion=name  [--overwrite]	 [--help]  [--verbose]	[--quiet]  [--ui]

   Flags:
       --overwrite
	   Allow output	files to overwrite existing files

       --help
	   Print usage summary

       --verbose
	   Verbose module output

       --quiet
	   Quiet module	output

       --ui
	   Force launching GUI dialog

   Parameters:
       red=nameA [required]
	   Name	of input raster	map (red)

       green=nameA [required]
	   Name	of input raster	map (green)

       blue=nameA [required]
	   Name	of input raster	map (blue)

       hue=nameA [required]
	   Name	for output raster map (hue)

       intensity=nameA [required]
	   Name	for output raster map (intensity)

       saturation=nameA	[required]
	   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 satura-
       tion of the data.  The output raster map	layers are created by a	 stan-
       dard  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.
