4.5.11 is_HideDDOverlay
Syntax
INT is_HideDDOverlay (HIDS hCam)
Description
Attention
This function is obsolete and should not be used anymore. We recommend to use the is_DirectRenderer()
function instead (see also Obsolete functions ).
In DirectDraw BackBuffer mode, is_HideDDOverlay() hides the overlay. Only the contents of the image buffer
will be displayed. This way, the frame rate is higher on some systems than with the overlay shown. By hiding the
overlay, its data is not lost.
