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.

USAGE

       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.

MEMORY REQUIRED

       Line.

OPTIONS

       [-q]

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

       [-s]

               Select the global screen color map.

       [-l map]

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

       [-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.

       [-g Gamma]

               Apply gamma correction to selected color map.

       [-i image]

               Select the color map of the numbered image.

       [-h]

               Print one command line help, similar to Usage above.

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.
