IltmmCapture::CaptureDIB

#include "ltmm.h"

C Syntax	HRESULT IltmmCapture_CaptureDIB(pCapture, phDIB)
C++ Syntax	HRESULT CaptureDIB(phDIB)

 

IltmmCapture *pCapture;	/* pointer to an interface */
long *phDIB;	/* DIB handle */

Captures a device independent bitmap.

Parameter	Description
pCapture	Pointer to an IltmmCapture interface.
phDIB	Pointer to a variable that receives the handle to the DIB.

Returns

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.

Comments

This function will capture a single device independent bitmap.

If the method succeeds, the caller must free the returned HDIB by calling the GlobalFree function.

 

Note: The frame data is retrieved from the underlying graph after the processing

 filters. If the capture needs to occur before the processing is completed

 use the LeadVideoCallBackFilter and place it first in the collection of

 processing filters.
