NAME
       gif2rgb - convert images	saved as GIF to	24-bit RGB triplets

SYNOPSIS

       gif2rgb [-v] [-1] [-c colors] [-s width height] [-o outfile] [-h]
	       [gif-file]

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

       -1
	   Only	one file in the	format of RGBRGB... triplets (Each of R, G,B
	   is a	byte) is being read or written.	This file size is 3 * Width *
	   Height. If stdin is used for	input or stdout	for output, this
	   option is implicitly	applied. The default (if not `-1') is 3	files
	   with	the names OutFileName.R, OutFileName.G,	OutFileName.B, each of
	   which is Width * Height bytes.

       -c colors
	   Specifies number of colors to use in	RGB-to-GIF conversions,	in
	   bits	per pixels, so '-c 8' actually specifies 256 colors (maximum
	   and default).

       -s width	height
	   Sets	RGB-to-GIF conversion mode and specifies the size of the image
	   to read.

       -o
	   specifies the name of the out file (see also	`-1' above).

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

       By default, convert a GIF input file to RGB triplets. If	-s is
       specified, convert RGB input to a GIF.

       If no input file	is given, gif2rgb will try to read data	from stdin.

BUGS
       Feeding this utility a GIF with an invalid colormap, or other kinds of
       malformations, index will produce invalid output	and may	core-dump the
       tool. Don't do that.
