I have scanned documents that I am going OMR. Each document contains a QR code in the upper right which contains a unique identified for each page. Because these images are scanned using a document feeder, there is a chance the document may be scanned upside down because we do not require our users to make all the pages face the same way. I am about to begin writing the code to detect/read the QR code, but I was curious if I needed to verify the orientation of the page before calling BarcodeQRReaderDoScan(), or if that function was capable of detecting the QR code even if it's upside down? If it can, I can use the resulting X and Y position information from the QR scan to determine if I need to rotate...otherwise I need to determine orientation first, then do the QR scan.
