GIFCLRMP(1) GIFLIB Documentation GIFCLRMP(1) NAME gifclrmp - extract colormaps from GIF images SYNOPSIS gifclrmp [-v] [-s] [-l mapfile] [-t trans] [-g gamma] [-i image] [-h] [gif-file] DESCRIPTION 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. 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. AUTHOR Gershon Elber. GIFLIB 2 May 2012 GIFCLRMP(1)
