PageBitmapOcrReady Event (GdPicturePDF)
This event is raised when a specified image is ready to be sent to the OCR engine during the process invoked by the
GdPicturePDF.OcrPage or the
GdPicturePDF.OcrPages methods. It is fired after the
GdPicturePDF.BeforePageOcr event. This event is particularly useful to apply your specific custom pre-processing to the image before recognizing it.
Please check the corresponded GdPicturePDF.PageBitmapOcrReadyEventHandler for given parameters.
The PDF to PDF-OCR sample included in the
