| 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.<P> |
| |
| <H1>Usage:</H1> |
| |
| <pre> |
| gifclrmap [-q] [-s] [-t trans] [-l map] [-g Gamma] [-i image] [-h] gif-file |
| </pre> |
| |
| If no gif-file is given, GifClip will try to read a GIF file from stdin.<P> |
| |
| <H1>Memory required:</H1> |
| |
| Line. |
| |
| <H1>Options:</H1> |
| |
| <DL> |
| <DT> [-q] |
| <DD> Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout |
| of running scan lines. Use -q- to invert.<P> |
| |
| <DT> [-s] |
| <DD> Select the global screen color map.<P> |
| |
| <DT> [-l map] |
| <DD> Load color map from this file instead of selected color map.<P> |
| |
| <DT> [-t trans] |
| <DD> 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.<P> |
| |
| <DT> [-g Gamma] |
| <DD> Apply gamma correction to selected color map.<P> |
| |
| <DT>[-i image] |
| <DD> Select the color map of the numbered image.<P> |
| |
| <DT>[-h] |
| <DD> Print one command line help, similar to Usage above.<P> |
| </DL> |
| |
| <H1>Notes:</H1> |
| |
| <UL> |
| <LI> |
| The default operation is to dump out the selected color map in text |
| format.<P> |
| |
| <LI> |
| 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.<P> |
| </UL> |
