Read our full Adobe Acrobat Reader DC reviewįoxit PDF Reader is more than just a free PDF reader – you can also create PDFs from scratch using this software. If you can overlook this, it’s a great tool, but there are less obtrusive ones out there. Sadly, the adware side of things is pretty much everywhere: you get ‘try now’ buttons, you’re offered to use powerful tools but later are asked to pony up some cash in order to actually use them, there’s even a ‘7-day trial’ button. In our review, we reckoned that “Adobe Acrobat Reader DC is one of the best free PDF readers for anyone looking to view documents and manipulate them in some way.” It’s simple, easy to use, and comes with all the basic features you need to interact with PDF files. If it wasn’t for the latter, Acrobat Reader would be a decent addition to your software library. The second is to convince you to upgrade to the paid version of the software (which, you’ve guessed it, has many more features, including the ability to create and edit PDF files). If no QR code can be decoded, it will return None.The top PDF viewer is designed with two purposes in mind: the first is to enable you to read and interact with PDF files (including adding annotations and even signing a document). If None, it will look for the QR code in the whole image (not recommended). The bounding box of the QR code in the format ( x1, y1, x2, y2). Internally, this method will run the pyzbar decoder, using different image preprocessing techniques ( sharpening, binarization, blurring.) every time it fails to increase the detection rate.ībox: tuple | None. This method decodes a single QR code on the given image, if a bbox is given (recommended) it will only look within that delimited region. NOTE: This the only function you will need? Take a look at QRDet. The image must is expected to be in uint8 format, RGB. NumPy Array containing the image to decode. This method detects the QR codes in the image and returns the bounding boxes surrounding them in the format ( x1, y1, x2, y2). If return_bboxes is False, the output will look like: ('Decoded QR 1', 'Decoded QR 2', None, 'Decoded QR 4'. Returns: tuple | tuple, str | None]]: A tuple with all detected QR codes decodified. If True, it will also return the bboxes of each detected QR. ![]() The image is expected to be in uint8 format, RGB. This method will decode the QR codes in the given image and return the decoded strings (or None, if any of them could be detected but not decoded). ![]() API Reference tect_and_decode(image, return_bboxes = False) NOTE: Some entries can be None, it will happen when a QR have been detected but couldn't be decoded. ![]() detect_and_decode( image = image)ĭetect_and_decode will return a tuple containing the decoded string of every QR found in the image. # Use the detect_and_decode function to get the decoded QR data decoded_text = qreader. # Get the image that contains the QR code (QReader expects an uint8 numpy array) image = cv2. From qreader import QReader import cv2 # Create a QReader instance qreader = QReader()
