\w'gif2rgb 'u gif2rgb [-v] [-1] [-c colors] [-s width height] [-o outfile] [-h] [gif-file]
-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\*(Aq) 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 \*(Aq-c 8\*(Aq 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\*(Aq 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.
