Member Function Documentation

◆ frameReady()

void ICCapturingListener::frameReady	(	DShowLib::Grabber &	caller,
		smart_ptr< DShowLib::MemBuffer >	pBuffer,
		DWORD	FrameNumber
	)

virtual

Overridden GrabberListener method for calling the saveImage method to save the image buffer to disk

The frameReady() method calls the saveImage method to save the image buffer to disk.

Definition at line 47 of file ICCapturingListener.cxx.

◆ overlayCallback()

void ICCapturingListener::overlayCallback	(	DShowLib::Grabber &	caller,
		smart_ptr< DShowLib::OverlayBitmap >	pBitmap,
		const DShowLib::tsMediaSampleDesc &	MediaSampleDesc
	)

virtual

Overridden GrabberListener method for drawing the number of the current frame

The overlayCallback() method draws the number of the current frame. The frame count is a member of the tsMediaSampleDesc structure that is passed to overlayCallback() by the Grabber.

Definition at line 34 of file ICCapturingListener.cxx.

◆ saveImage()

void ICCapturingListener::saveImage	(	smart_ptr< DShowLib::MemBuffer >	pBuffer,
		DWORD	currFrame
	)

Save one image and mark it as saved

The image passed by the MemBuffer pointer is saved to a BMP file.

Definition at line 72 of file ICCapturingListener.cxx.

◆ setBufferSize()

void ICCapturingListener::setBufferSize ( unsigned long NumBuffers )

Setup the buffersize

Initialize the array of bools that is used to memorize, which buffers were processed in the frameReady() method. The size of the array is specified by the parameter NumBuffers. It should be equal to the number of buffers in the FrameHandlerSink. All members of m_BufferWritten are initialized to false. This means that no buffers have been processed.

Definition at line 64 of file ICCapturingListener.cxx.

◆ SetICCapturingSourceNewFrameCallback()

void ICCapturingListener::SetICCapturingSourceNewFrameCallback ( ICCapturingSourceNewFramePtr cb )

inline

Set new frame callback function

Definition at line 42 of file ICCapturingListener.h.

ICCapturingSourceNewFramePtr ICCapturingListener::ICCapturingSourceNewFrameCallback

protected

Pointer to the callback function that is executed each time a frame is grabbed
