•Click Edit to change the language and/or accuracy of the OCR operation. Note than increasing the accuracy will also increase the time taken to perform the operation and vice versa. Note that two optical character recognition engines are available in PDF-XChange Editor: the Default OCR engine and the Enhanced OCR engine, which is available when PDF-XChange Editor Plus is purchased (either as a stand-alone product or as part of the PDF-XChange PRO bundle). The Enhanced OCR engine is faster, more accurate and more dynamic than the default OCR engine, and it also contains some extra features. Further information about the Enhanced OCR engine is available here. The differences between these engines are detailed here.
