     RGBmode(3G)                                           RGBmode(3G)



     NAME

          RGBmode - sets a display mode that bypasses the color map


     SPECIFICATION

          C         RGBmode()




          FORTRAN   subroutine RGBmod


     DESCRIPTION

          RGBmode makes the system interpret the contents of the

          bitplanes as RGB values.  The system writes 8-bit values of

          red, green, and blue into the bitplanes; these values

          directly control the intensity of the color displayed on the

          monitor. RGB mode is useful with 12 or more bitplanes.  With

          24 bitplanes, 8 bits of red, green, and blue are used.  With

          fewer than 24 bitplanes, 12 bitplanes are used, 4 bits of

          red, green, and blue.  The four most significant bits are

          used.



          You must call gconfig for RGBmode to take effect.
