rgb2gif
A program to convert 24 bit images to a GIF image using color quantization.
Usage:
rgb2gif [-q] [-c #Colors] [-1] -s Width Height [-h] RGBFile
If no RGBFile is given, RGB2Gif will try to read a GIF file from stdin.
Memory required:
Screen.
Options:
- [-q]
- Quiet mode. Defaulte off on MSDOS, on under UNIX. Controls printout
of running scan lines. Use -q- to invert.
- [-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.
