<CENTER><H1>rgb2gif</H1></CENTER>
A program to convert 24 bit images to a GIF image using color quantization.<P>
<H1>Usage:</H1>
<pre>
rgb2gif [-q] [-c #Colors] [-1] -s Width Height [-h] RGBFile
</pre>
If no RGBFile is given, RGB2Gif will try to read a GIF file from stdin.<P>
<H1>Memory required:</H1>
Screen.
<H1>Options:</H1>
<DL>
<DT> [-q]
<DD> Quiet mode. Defaulte off on MSDOS, on under UNIX. Controls printout
of running scan lines. Use -q- to invert.<P>
<DT> [-c #Colors]
<DD> Specifies number of colors to use, in bits per pixels, so
`-c 8' specifies actually 256 colors (maximum and default).<P>
<DT> [-1]
<DD> 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.<P>
<DT> [-s Width Height]
<DD> Specifies the size of the image to read.<P>
<DT> [-h]
<DD> Print one line of command line help, similar to Usage above.<P>
</DL>
