# gifclrmp(1)

extract colormaps from GIF images

## 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.
