event EventHandler<OcrAutoRecognizeJobOperationEventArgs^>^ JobOperation def JobOperation(sender,e): # sender: IOcrAutoRecognizeManager e: OcrAutoRecognizeJobOperationEventArgs The event handler receives an argument of type OcrAutoRecognizeJobOperationEventArgs containing data related to this event. The following OcrAutoRecognizeJobOperationEventArgs properties provide information specific to this event.
| Property | Description | 
|---|---|
| Document | Gets the OCR document being used in the current operation. | 
This event will occur when Run, RunJob or RunJobAsync is called.
You can use this event to get information on the current operation (creating an OCR document, loading a page, zoning, recognizing, saving, etc.).
