.SH NAME
gifclrmp \- 
A program to modify GIF image colormaps.  Any local colormap in a GIF file can
be modified at a time, or the global screen one.

.SH USAGE

.B gifclrmap [\-q] [\-s] [\-t trans] [\-l map] [\-g Gamma] [\-i image] [\-h] gif\-file


If no gif\-file is given, GifClip will try to read a GIF file from stdin.

.SH MEMORY REQUIRED

Line.

.SH OPTIONS

.IP [\-q]

 Quiet mode.  Defaults off on MSDOS, on under UNIX.  Controls printout
of running scan lines.  Use \-q\- to invert.

.IP [\-s]

 Select the global screen color map.

.IP "[\-l map]

 Load color map from this file instead of selected color map.

.IP "[\-t trans]

 Change color index values.  The change is made to both
the selected color table and the raster bits of the selected image.  A
translation file is a list of pairs of `before' and `after' index values.
At present, the `before' index values must be in ascending order starting
from 0.

.IP "[\-g Gamma]

 Apply gamma correction to selected color map.

.IP "[\-i image]

 Select the color map of the numbered image.

.IP [\-h]

 Print one command line help, similar to Usage above.


.SH NOTES


\- The default operation is to dump out the selected color map in text
format.

\- The file to load/dump is simply one color map entry per line.  Each such
entry line has four integers: "ColorIndex Red Green Blue", where color
index is in ascending order starting from 1.
