ShapeOverlay

property

Delphi
property ShapeOverlay: TShape read GetShapeOverlay write SetShapeOverlay;
C++Builder
__property Vcl::Extctrls::TShape* ShapeOverlay = {read=GetShapeOverlay, write=SetShapeOverlay};

TShape component assigned to TVideoGrabber that will be drawn over video frames. The TShape component is really drawn over video frames when ShapeOverlayEnabled is true. To use this feature, simply put a TShape component on the form, then, using the object inspector, assign ShapeOverlay to it. It is possible to draw more than one shape over video frames by using ShapeOverlayList instead of this property. Notes:

  • to avoid having TShape components placed on a form visible at runtime, simply set their Visible property to false.

  • to use this property, the frame grabber is enabled.
