I have thousands of PDF files. Our kind hearted person who scanned them all into existence must have gone glazed over at some point, because some selection of pages were scanned upside down.
I've calculated that to manually review all of these pages will take in the realm of 12 hours. This does not factor in correction (there is also a digital label affixed right side up, bonus points if you can figure out how to maintain that!).
Any help or notion of which direction to search would be much appreciated.
