For more information on recognition of OCR data a page, refer to IOcrPage.Recognize.
This method will iterate through all the pages between firstPageIndex and lastPageIndex in the OCR document and run IOcrPage.Recognize on each page.
To recognize all the pages in the OCR document use Recognize(OcrProgressCallback callback).
You can use the OcrProgressCallback to show the operation progress or to abort it. For more information and an example, refer to OcrProgressCallback.
