Syntax
INT is_EnableDDOverlay (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This function is obsolete and should not be used anymore.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_EnableDDOverlay() enables live overlay mode. The overlay cannot be
displayed directly, but needs to be visualized before by calling is_ShowDDOverlay() . The overlay uses black
as the so-called key color, so that overlay graphics may not contain any black color.
