colormaps in .im8 rasterfiles

[Christopher Hull]

	I have been trying to display some rasterfiles(.im8) images 
from my own program.  The files in particular are the ones the NeWS
imagedemo program uses (/usr/NeWS/smi) on the personal irises.  The
problem I am having is interpreting the colormap in the file.  My 
program displays the image and it is recognizable however the colors 
are definitely incorrect.  
	Right now I am using each byte in the image as an direct 
offset into each of the red, green, and blue colormaps, and plotting
a pixel with those components.  I have tried reversing and/or invert-
ing the colormaps with out any success.  Does anyone know how to 
correctly interpret the colormaps, or know how the NeWS operator
`imagecanvas' interprets the rasterfiles?  Any help or pointers would
be greatly appreciated.

Thanx,
