# rgb2gif(1)

A program to convert 24 bit images to a GIF image using color quantization.

## NAME

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.
