NAME

6       gifclrmp - extract colormaps from GIF images
7

SYNOPSIS

9       gifclrmp [-v] [-s] [-l mapfile] [-t trans] [-g gamma] [-i image] [-h]
10                [gif-file]

DESCRIPTION

13       A program to modify GIF image colormaps. Any local colormap in a GIF
14       file can be modified at a time, or the global screen one.
15

OPTIONS

17       -v
18           Verbose mode (show progress). Enables printout of running scan
19           lines.
20
21       -s
22           Select the global screen color map.
23
24       -l mapfile
25           Load color map from this file instead of selected color map.
26
27       -t trans
28           Change color index values. The change is made to both the selected
29           color table and the raster bits of the selected image. A
30           translation file is a list of pairs of `before' and `after' index
31           values. At present, the `before' index values must be in ascending
32           order starting from 0.
33
34       -g gamma
35           Apply gamma correction to selected color map.
36
37       -i image
38           Select the color map of the numbered image.
39
40       -h
41           Print one command line help, similar to Usage above.
42
43       If no GIF file is given, gifclip will try to read a GIF file from
44       stdin.
45

NOTES

47       ·   The default operation is to dump out the selected color map in text
48           format.
49
50       ·   The file to load/dump is simply one color map entry per line. Each
51           such entry line has four integers: "ColorIndex Red Green Blue",
52           where color index is in ascending order starting from 1.
