gif2rgb] [\-s `width `heightVerbose 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). Sets RGB\-to\-GIF conversion mode and specifies the size of the image to read. 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 adata from stdin.``
