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This function is obsolete and should not be used anymore.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. |
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.
