Note that two optical character recognition engines are available in PDF-Exchange Editor: the Default OCR engine and the Enhanced OCR engine, which is available when PDF-Exchange 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.
