Example

For an example on how to insert a page, refer to InsertPage. For an example on how to add pages from a disk file, refer to AddPages.

Remarks

A short-cut to insert all the pages of a disk file to the OCR document is InsertPages(index, fileName, 1, -1, callback).

To insert a single page from a multi-page disk file, you can also use AddPage(int pageIndex, string fileName, OcrProgressCallback callback).

The image file in fileName can be any of the file formats supported by LEADTOOLS. For more information, refer to Summary of All Supported Image File Formats.

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.
