man rgb2gif (Commandes) - Program to convert 24 bit images to a GIF.
NAME
rgb2gif - Program to convert 24 bit images to a GIF.
SYNOPSIS
rgb2gif [-q] [-c #Colors] [-1] -s Width Height [-h] RGBFile
DESCRIPTION
A program to convert 24 bit images to a GIF image using color quantization.
If no RGBFile is given, RGB2Gif will try to read a GIF file from stdin.
OPTIONS
Quiet mode. Defaulte off on MSDOS, on under UNIX. Controls printout of running scan lines. Use -q- to invert. Specifies number of colors to use, in bits per pixels, so '-c 8' specifies actually 256 colors (maximum and default). 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. Specifies the size of the image to read. Print one line of command line help, similar to Usage above.
