Hi,


  I have written a program that converts sun raster files to PICT
format, but the colors are off.  The sun uses 8 bit values in its
color lookup table, while the Mac uses 16 bit values.  I simply shift
the RGB components left 8 times - but that introduces green in some
parts of the image, that should be orange.

  How should one go around converting 8 bit color values to 16 bits,
and vice versa.

  Thanks in advance.
