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.
Load color map from this file instead of selected color map.
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.
Apply gamma correction to selected color map.
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.
