gifclrmp(1)
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.
