Jeff,
Both put_update and editimage understand the 24-bit visual. If you have a
3-band viff of colormap type genericRGB or ntscRGB, pumping it to either
of these display routines should produce a true color image. If you still
get the prompt to allow compression to 8 bits by an internal call to vgamut,
this probably means you've started up your X server in 8-bit mode.
BTW, I don't have a Sun GS, but rather a Parallax XVideo board, which is
also a 24-bit frame buffer (also has a true color RGB digitizer!). Mine
works as noted above.
Hope this helps.
Wade
