RemoveResultReceiver

Removes the specified ICapturedResultReceiver object.

void RemoveResultReceiver(ICapturedResultReceiver receiver);

Parameters

[in] receiver: The receiver object, of type ICapturedResultReceiver.

[in] completionHandler: A CompletionListener the system calls after it finishes the StartCapturing.

StopCapturing

Stops the capturing process.

void StopCapturing();

AddResultFilter

void AddResultFilter(ICapturedResultFilter filter);

Parameters

[in] filter: The filter object, of type CapturedResultFilter. Currnetly, is must be a MultiFrameCrossFilter object.

RemoveResultFilter

Removes the specified CapturedResultFilter object.

void RemoveResultFilter(ICapturedResultFilter filter);

Parameters
