gifclrmp(1) A program to modify GIF image colormaps. Any local colormap in a GIF file can


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.





 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 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.
