Syntax

INT is_EnableDDOverlay (HIDS hCam)

Description

Achtung

This function is obsolete and should not be used anymore.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

Input Parameters

hCam

Camera handle

Return Values

IS_SUCCESS

Function executed successfully

IS_NO_SUCCESS
