Attached is a project that showcases how to utilize our OCR and Barcode engine libraries to produce a QR code from recognized OCR text. This project will AutoZone the
passed document, recognize the text, generate a QR code from this text, automatically crop the resulting image to only contain the barcode, and open the resulting file in your default image viewing application.

Below are pages to our documentation with classes used in this application.
