RGB2GIF(1)

NAME
rgb2gif - convert 24-bit images to GIF images using color quantization

SYNOPSIS

rgb2gif [-v] [-c colors] [-1] -s width height [-h] [rgb-file]

OPTIONS

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

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

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

-s width height
    Specifies the size of the image to read.

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

If no rgb-file is given, rgb2gif will try to read RGB data from stdin.
