PDF with (already recognized) text and (non recogn.) Images

Post by BennyCUAG » Mon Jul 22, 2013 11:46 am


we have a OCR-PDF file with both, text and embedded images. The text is already recognized (100% correct) by an OCR engine, the image is not.
It is posible to get a full OCR-PDF with the OLD recognized text and the new text from the embedded images??

- GdPictureImaging1.PdfOCRStart
Image := GdPicturePDF1.RenderPageToGdPictureImageEx(..)
- GdPictureImaging1.PdfOCRStop

I can only process the whole page with recognizing the old text again..
