Inserts the image stored in a URI to the specified location.
Overloads Function InsertPage( _
ByVal pageIndex As Integer, _
ByVal uri As Uri, _
ByVal callback As OcrProgressCallback _
) As IOcrPage
The zero-based index at which uri should be inserted.
A URI containing the path to the image.
Optional callback to show operation progress.
The IOcrPage object that define the newly inserted page.
This method will load the first page from a raster image file in the URI and inserts it to the OCR document at the specified location.
The URI can point to a file in a remote HTTP server, UNC or FTP.
To insert all or specific range of the pages of a multipage image from a URI to the OCR document, use the InsertPages(int pageIndex, Uri uri, int imageFirstPageNumber, int imageLastPageNumber, OcrProgressCallback callback) method.
If you passed a RasterCodecs object to the IOcrEngine.Startup, then this method will use the same RasterCodecs object to load the raster image file. If you did not pass a RasterCodecs object, the engine will create an instance the first time one of the add or export page methods is called.
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.
