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).
