Syntax
INT is_EnableDDOverlay (HIDS hCam)
Description
This function is obsolete and should not be used anymore.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 visualised before by calling is_ShowDDOverlay() .
The overlay uses black as the so-called key colour, so that overlay graphics may not contain any
black colour.
