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