Occurs when a job is being run to provide progress status and ability to abort.
public event EventHandler<OcrAutoRecognizeJobProgressEventArgs> JobProgress
Event JobProgress As EventHandler(Of OcrAutoRecognizeJobProgressEventArgs)
- (void)autoRecognizeManager:(LTOcrAutoRecognizeManager *)manager progress:(LTOcrProgressData *)progressData
event EventHandler<OcrAutoRecognizeJobProgressEventArgs^>^ JobProgress
The event handler receives an argument of type OcrAutoRecognizeJobProgressEventArgs containing data related to this event. The following OcrAutoRecognizeJobProgressEventArgs properties provide information specific to this event.
Property | Description |
---|---|
Data | Gets the event progress data. |
Note, this event will not trigger if multiple threads are used on the same document (the value of MaximumThreadsPerJob is anything else but 1).
