ncl_gclrwk: clears a workstation.
NAMEGCLRWK (Clear workstation) - clears a workstation.
SYNOPSISCALL GCLRWK (WKID, COFL)
C-BINDING SYNOPSIS#include <ncarg/gks.h>
- (Integer, Input) - A number identifying the workstation to be cleared. WKID must be the same as that used in some previous GOPWK call.
(Integer, Input) -
Clear the workstation display
surface. Options are:
- Check to see if the display surface is empty. If so, do not issue a clear surface command.
- Issue a clear surface command whether the surface has been written to or not.
USAGEFor workstations of type "1" (CGM), GCLRWK is interpreted as a picture termination in CGM generation. If COFL = 0 and no output primitives have been written in the current picture, then a call to GCLRWK is a "do nothing"; otherwise, it generates an END PICTURE element (as well as other picture initializing elements). If COFL = 1, then a call to GCLRWK generates an END PICTURE.
For workstations of types "7" or "8" (see the man page for GOPWK for a description of workstation types) clear workstations erases all primitives that appear on the screen.
ACCESSTo use GKS routines, load the NCAR GKS-0A library ncarg_gks.
