SGIPaletteImg
DESCRIPTION
Convert to a RGB palette color model using a default SGI lookup table. The
RGB image is dithered and then mapped to the lookup table. The output is
intended to be suitable for writing to a colormap window using rectwrite()
or writepixels(). The dithering matrix used is:
0 8 2 10
2 4 14 6
3 11 1 9
5 7 13 5
