Options:
[-q]
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout
of running scan lines. Use -q- to invert.
[-s]
Select the global screen color map.
[-l map]
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.
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.
