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.
