We are having a problem using some GPR calls on a DN 550.

A faculty member here at U.Lowell is trying to do imaging using
the graphics primitives calls supplied with SR9 on a DN 550.
He first tried his program on a DN 660 and it worked just like
the manual described, but upon trying it on a DN 550 any color
intensity he wrote was translated to one between 240 and 255.

The main calls we are using are:
		gpr_$borrow
	and     gpr_$set_imaging_mode

The manuals have examples for just about every other call implemented,
but none for the set_imaging_mode.

Is there anybody out there with a simple example of the imaging mode
in C, Pascal, or Fortran?

Thanks,
