Syntax

[C/C++:]
void gEnqViewport2D(GLIMIT *piclim2, GLIMIT *viewlim);
void gEnqViewport3D(GLIMIT3 *piclim3, GLIMIT *viewlim);

[F90:]
subroutine gEnqViewport2D(piclim2, viewlim)
subroutine gEnqViewport3D(piclim3, viewlim)

type (GLIMIT), intent(out) :: piclim2,viewlim
type (GLIMIT3), intent(out) :: piclim3

Arguments

piclim2, piclim3
Picture coordinate range

viewlim
Viewport coordinate range in current paper units

Description

The routine gEnqViewport2D() returns both the ranges of user picture coordinates and viewport coordinates used in calculating the viewport mapping.

The values returned are either those set by gSetViewport2D() or if gSetViewport2D() has not been called, the default values for both ranges are the same as the current paper limits as set by gSetDrawingLimits() or the device defaults.
