NAME

RGBmode - sets a display mode that bypasses the color map

SPECIFICATION

C
RGBmode()

FORTRAN
subroutine RGBmod

Pascal
procedure RGBmode;

DESCRIPTION

There are three display modes: single buffer, double buffer, and RGB.  In RGB mode, all the bitplanes are simultaneously written and displayed.  Eight-bit values of red, green, and blue are written into the bitplanes, and directly control the monitor’s intensity.  RGB mode is useful only when the system has 24 bitplanes: the first sixteen are shared equally between red and green; the last eight define the blue component.  A twelve-plane system provides one-quarter the maximum intensity in red and green, and no blue at all.  RGBmode does not take effect until gconfig is called.

NOTE

This command can be used only in immediate mode.
