> If you're using an OCR engine to understand PDFs that are nothing but a scanned image embedded in a PDF... what do you need a PDF parser for?
This should be obvious, but the answer is because OCR engines are not terribly accurate. If you have a native PDF, you're far better off parsing the PDF then converting to an image and OCRing. But if OCR ever becomes perfect, then sure.
