Visual Basic (Usage)	Copy Code
Dim instance As IOcrPageCollection Dim pageIndex As Integer Dim image As RasterImage Dim callback As OcrProgressCallback Dim value As IOcrPage   value = instance.InsertPage(pageIndex, image, callback)

IOcrPage InsertPage( 
   int pageIndex,
   RasterImage image,
   OcrProgressCallback callback
)

IOcrPage^ InsertPage( 
   int pageIndex,
   RasterImage^ image,
   OcrProgressCallback^ callback
) 

Parameters

pageIndex

The zero-based index at which image should be inserted.

image

The Leadtools.RasterImage object containing the page to insert.

callback

Optional callback to show operation progress.

Return Value

This method copies the Leadtools.RasterImage object image data into the newly created IOcrPage. Therefore, after this method returns, there is no relationship between image and the IOcrPage inside the OCR document. For example, if you do not need the image object after calling this method, you should dispose it after this method returns.

This method guarantees that no changes will be made to image.

If image contains more than one page, then the current page as defined in RasterImage.Page is the one inserted to the OCR document.

To insert all or specific range of the pages of a multi-page Leadtools.RasterImage object to the OCR document, either iterate through the pages by changing to the value of RasterImage.Page to go from 1 to RasterImage.PageCount or use the InsertPages(int pageIndex, RasterImage image, int imageFirstPageNumber, int imageLastPageNumber, OcrProgressCallback callback) method.

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

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 LEADTOOLS Plus OCR engine does not support image size greater than A3 paper size (11.7 by 16.5 inches at 300 dpi). Attempting to add an image that has a size greater than A3 will result in an error. For document of size greater than the maximum allowed, you must first resize the image before adding it to the LEADTOOLS Plus OCR engine. The Professional and Advantage engines do not have a restriction on the image size.
