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 OcrPage or the OcrPages(String,Int32,String,String,String,Single) methods. It is fired after the BeforePageOcr event. This event is particularly useful to apply your specific custom pre-processing to the image before recognizing it.
