MGL_getViewport

Returns the currently active viewport.

Declaration

void MGLAPI MGL_getViewport(
rect_t *view)

Prototype In

mgraph.h

Parameters

view | Place to store the current viewport

Description

This function returns a copy of the currently active viewport. These dimensions are global to the entire device context surface. When the viewport is changed with this function, the viewport origin is reset to (0,0).

All output in MGL is relative to the current viewport, so by changing the viewport to a new value you can make all output appear in a different rectangular portion of the device surface.
