Job Property

Summary

Gets the job associated with this operation.

Syntax

Objective-C

C++/CLI

Java

Python

public IOcrAutoRecognizeJob Job { get; }

@property (nonatomic, strong, readonly) LTOcrAutoRecognizeJob *job;

public OcrAutoRecognizeJob getJob()

public: 
property IOcrAutoRecognizeJob^ Job { 
   IOcrAutoRecognizeJob^ get(); 
}

Job # get  (OcrAutoRecognizeJobOperationEventArgs)

Property Value

The instance of the IOcrAutoRecognizeJob currently being run.

Remarks

You can use this member to get information about the job, for example, the image file name and page numbers to recognize and the output document file name and format through IOcrAutoRecognizeJob.JobData. Note that OcrAutoRecognizeJobData.LastPageNumber will have the true value of the last page number in the image file if a value of -1 (for up to last page) was passed in the original object used to create IOcrAutoRecognizeJob.
