gif2rgb − convert images saved as GIF to 24−bit RGB triplets
gif2rgb [−v] [−1] [−c colors] [−s width height] [−o outfile] [−h] [gif−file]
Verbose mode (show progress). Enables printout of running scan lines.
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.
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.
specifies the name of the out file (see also ‘−1' above).
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.
