public void insertPages(int pageIndex,
The zero-based index at which the new pages from stream should be inserted.
The .NET stream containing the multi-page image file.
1-based index of the first page in stream to insert.
Optional callback to show operation progress.
A short-cut to insert all the pages of an image file stored in a stream to the OCR document is
InsertPages(index, stream, 1, -1, callback).
To insert a single page from a multi-page image stored in a stream, you can also use AddPage(int pageIndex, Stream stream, OcrProgressCallback callback).
The LEADTOOLS OCR engine supports pages of dots per inch (DPI) values of 150 and greater. If you try to add a page with a DPI of less than 150 then the engine might be able to recognize any data from this page.
Note: The value of the "Recognition.ShareOriginalImage" (only supported by the LEADTOOLS OCR Module - LEAD Engine) setting is not used when calling this method. The engine loads the image(s) and sets them in the pages internally. The original image reference can be obtained from the page using IOcrPage.GetRasterImage(OcrPageType.Original). Sharing the original image minimizes the memory used during OCR operations.
This member only works with memory-based documents and will throw an exception otherwise. For more information, refer to IOcrDocumentManager.CreateDocument and Programming with the LEADTOOLS .NET OCR.
