Summary

Retrieves a device independent bitmap during a ltmmCapture_Mode_Still capture.

Syntax

#include "ltmm.h"

Platform	Syntax
C	HRESULT IltmmCapture_GetStillHDIB(pCapture, TimeOut, phDIB)
C++	HRESULT GetStillHDIB(TimeOut, phDIB)

Parameters

IltmmCapture * pCapture

Pointer to an IltmmCapture interface.

long TimeOut

Value containing the maximum time, in milliseconds, to wait for the image.

LONG_PTR *phDIB

Pointer to a variable that receives the DIB handle.

Returns

Value	Meaning
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

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

The frame is captured from the position indicated by the StillTap property.

When capturing from the still pin, the capture happens when the user presses the hardware button for capturing the still image.

If there is not a hardware button or the user does not press it, the capture occurs after the timeout specified by the TimeOut parameter.

When not capturing from the still pin, the capture occurs after the amount of time specified by the TimeOut parameter.

If TimeOut is INFINITE, the function's time-out interval never elapses.
