3.2 Palette Maps
If you have a VGA, MCGA, Super-VGA, 8514/A, XGA, TARGA, or TARGA+ video
adapter, you can save and restore color palettes for use with any image.
To load a palette onto an existing image, use the <L> command in color-
cycling or palette-editing mode. To save a palette, use the <S> command
in those modes. To change the default palette for an entire run, use
the command line "map=" parameter.
The default filetype for color-map files is ".MAP".
These color-maps are ASCII text files set up as a series of RGB triplet
values (one triplet per line, encoded as the red, green, and blue [RGB]
components of the color).
Note that .MAP file color values are in GIF format - values go from 0
(low) to 255 (high), so for a VGA adapter they get divided by 4 before
being stuffed into the VGA's Video-DAC registers (so '6' and '7' end up
referring to the same color value).
Fractint is distributed with some sample .MAP files:
