NAME
       gifclrmp	- extract colormaps from GIF images

SYNOPSIS
       gifclrmp	[-v] [-s] [-l mapfile] [-t trans] [-g gamma] [-i image]	[-h]
		[gif-file]

DESCRIPTION
       A program to modify GIF image colormaps.	Any local colormap in a	GIF
       file can	be modified at a time, or the global screen one.

OPTIONS
       -v
	   Verbose mode	(show progress). Enables printout of running scan
	   lines.

       -s
	   Select the global screen color map.

       -l mapfile
	   Load	color map from this file instead of selected color map.

       -t trans
	   Change color	index values. The change is made to both the selected
	   color table and the raster bits of the selected image. A
	   translation file is a list of pairs of `before' and `after' index
	   values. At present, the `before' index values must be in ascending
	   order starting from 0.

       -g gamma
	   Apply gamma correction to selected color map.

       -i image
	   Select the color map	of the numbered	image.

       -h
	   Print one command line help,	similar	to Usage above.

       If no GIF file is given,	gifclip	will try to read a GIF file from
       stdin.

NOTES
       o   The default operation is to dump out	the selected color map in text
	   format.

       o   The file to load/dump is simply one color map entry per line. Each
	   such	entry line has four integers: "ColorIndex Red Green Blue",
	   where color index is	in ascending order starting from 1.
