NAME
gifclrmp - extract colormaps drom GIF imagesSYNOPSIS
- gifclrmp [-v] [-s] [-l mapfile] [-t trans] [-g gamma] [-i image] [-h] [gif-file]
DESCRIPTION
OPTIONS
-v
- Verbose mode (show progress). Enables printout of running scan lines.
-s
- Select the global screen color map.
-l mapfile
- 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.
If no GIF file is given, gifclip will try to read a GIF file from stdin.
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.
