GeometryEngine Component Functions 3
This section describes the GeometryEngine Component functions used to implement
overscanning.
GeometryEngineGetOverscan 3
This function allows your application to determine if overscan is currently on or off.
pascal ComponentResult
GeometryEngineGetOverscan ( ComponentInstance engineComponent,
short *overscan )
engineComponent
A valid instance of the GeometryEngine component.
overscan A value returned to your application indicating whether the
overscan function is currently on or off.
GeometryEngineSetOverscan 3
This function allows your application to decide whether overscan should be turned on
or off.
pascal ComponentResult
GeometryEngineSetOverscan ( ComponentInstance engineComponent,
short overscan )
engineComponent
A valid instance of the GeometryEngine component.
overscan A value passed by your application indicating the desired state of
the overscan setting.
VPTEngine Component 3
This section describes those VPTEngine component functions that can be used by the
developer. It is assumed that you are already familiar with the Component Manager
and, more specifically, with the AV Architecture to which the VPTEngine component
belongs. The section also supplies information on topics associated with the VPTEngine
component.
Overview 3
The VPTEngine component provides access to the color calibration features of the
AppleVision displays.
