callback
Optional callback to show operation progress.

Example

For an example, refer to IOcrDocumentManager and IOcrEngine.

Remarks

(Deprecated) Use IOcrDocument.Save(string, DocumentFormat, OcrProgressCallback) instead.

To save the output document to a .NET stream, use IOcrDocument.Save(Stream stream, OcrDocumentFormat format, OcrProgressCallback callback).

To get the extension used commonly with the document format specified in format, use DocumentWriter.GetFormatFileExtension.

Each IOcrPage object in the Pages collection of this IOcrDocument object holds its recognition data internally. This data is used by this method to generate the final output document.

Typical OCR operation using the IOcrEngine involves starting up the engine then creating a new IOcrDocument object using the IOcrDocumentManager.CreateDocument method before dding the pages into it and perform either automatic or manual zoning. Once this is done, you can use the IOcrPage.Recognize method of each page to collect the recognition data and store it internally in the page. After the recognition data is collected, you use the various IOcrDocument.Save methods to save the document to its final format as well as IOcrDocument.SaveXml to save as XML.

You can also use the IOcrPage.RecognizeText method to recognize and return the recognition data as a simple String object.

You can use IOcrDocument.Save as many times as required to save the document to multiple formats. You can also continue to add and recognize pages (through the IOcrPage.Recognize method after you save the document.

For each IOcrPage that is not recognized (the user did not call IOcrPage.Recognize and the value of the page IOcrPage.IsRecognized is still false) the IOcrDocument will insert an empty page into the final document.

To get the low level recognition data including the recognized characters and their confidence, use IOcrPage.GetRecognizedCharacters instead.

The IOcrDocument interface implements IDisposable, hence you must dispose the IOcrDocument object as soon as you are finished using it. Disposing an IOcrDocument object will free all the pages stored inside its IOcrDocument.Pages collection.

You can use the OcrProgressCallback to show the operation progress or to abort it. For more information and an example, refer to OcrProgressCallback.
