Defined in namespace Scandit.DataCapture.Core.Capture

IDataCaptureContextFrameListener

interface IDataCaptureContextFrameListener

Added in version 6.2.0

Interface for observing/listening to frame processing related events of a data capture context.

To observe changes of the data capture context’s frame processing, one or more IDataCaptureContextFrameListener may be added. These listeners provide hooks into different parts of the data capture context.

Frame processing only happens if at least one IDataCaptureMode is added.

OnFrameProcessingStarted()

void OnFrameProcessingStarted(DataCaptureContext dataCaptureContext, IFrameData frame)

Added in version 6.2.0

Called when a frame will be processed.

OnFrameProcessingFinished()

void OnFrameProcessingFinished(DataCaptureContext dataCaptureContext, IFrameData frame)

Added in version 6.2.0

Called when a frame has been processed.

FrameProcessingEventArgs

class FrameProcessingEventArgs : EventArgs

Added in version 6.12.0

Provides data for the DataCaptureContext.FrameProcessingStarted and DataCaptureContext.FrameProcessingFinished events.
