       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.


       gifclrmap [-q] [-s] [-t trans] [-l map]  [-g  Gamma]  [-i  image]  [-h]

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




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

               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.

               Print one command line help, similar to Usage above.


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

       - 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.
