RTRDataCaptureService protocol
A background data capture service protocol. Inherits from the RTRRecognitionService protocol.
This protocol is adopted by the data capture service object returned by the createDataCaptureServiceWithDelegate:profile: method. Its methods are used to tune the processing settings, pass video frames from the camera to the background processing engine, and release the resources afterwards.
The data capture service requires a delegate that conforms to the RTRDataCaptureServiceDelegate protocol. The service informs the delegate when the result is ready, sends progress information, warnings and errors.
