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.
