NAME

doublebuffer - set the display mode to double buffer mode

SYNOPSIS

C
doublebuffer()

FORTRAN
subroutine double

Pascal
procedure doublebuffer;

DESCRIPTION

Doublebuffer sets the display mode to double buffer mode.  It does not take effect until after a call to gconfig.  In double buffer mode, the bitplanes are partitioned into two groups, called the front and back planes.  Only the front planes are displayed.  Drawing commands normally update only the back planes; the frontbuffer and backbuffer commands can override the default. 

Gconfig sets frontbuffer = TRUE and backbuffer = FALSE in double buffer mode. 

SEE ALSO

backbuffer, frontbuffer, gconfig, getbuffer, getdisplaymode, RGBmode, singlebuffer, swapbuffers

NOTE

This command can only be used in immediate mode.
