Syntax

INT is_ReleaseDC (HIDS hCam, HDC hDC)

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This function is obsolete and should not be used anymore.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_ReleaseDC() releases the device context handle of the overlay buffer. If overlay display is enabled using the is_ShowDDOverlay() function, the contents of the overlay buffer will be updated on the screen after the handle release.

Input Parameters

hCam

Camera handle

hDC

Device context handle returned by is_GetDC()

Return Values

IS_SUCCESS

Function executed successfully

IS_NO_SUCCESS
