QRCode Library is a .NET component that can be used to encode and decode QRCode. QRCode is a 2 dimensional bar code that originated in Japan. Nowadays it is widely used in a wide range of industries, e.g. for vehicle parts tracking and inventory management. QR stands for Quick Response . It was created by the Japanese corporation Denso-Wave in 1994 and is aimed at decoding contents at high. Before you can decode a QR code, you must first take a picture of one. It's not clear which of these two things your question is about. The QR decode is platform-independent, but interfacing with a camera is 100% platform-dependent, and you don't mention your platform. - David Schwartz May 5 '12 at 17:4 cv.QRCodeDetector.decode(img, points[, straight_qrcode]) Decodes QR code in image once it's found by the detect() method. Returns UTF8-encoded output string or empty string if the code cannot be decoded. opiotnal output array of vertices of the found QR code quadrangle. Will be empty if not found One QR code can have over 7,000 characters encoded into it. QR code technology was developed in Japan in the year 1994 by Denso-Wave, a subsidiary of Toyota. As such, QR codes are capable of being encoded with the Kanji character set This submission includes files to encode a QR code from a string message, and decode a string message from an image containing an existing QR code. With little work these functions can be expanded to search for multiple bar-codes in images, decode multiple bar-codes in a single image etc

The method is plausible ofcourse, but it's highly time taking. As Kai Turner mentioned, the link is apt to learn the intricacies. It gives you proper guide for decoding. Starting from format version, finding first 5 bits, XORING them with standard.. The QR Code, or Quick Response Code barcode, is one of the most popular 2D barcodes available today and is used in a variety of industries including commercial tracking applications and mobile phone tagging applications If instead you simply want to decode a QR code from an image or your webcam use the Decode button, and the tool will automatically extra the data, and offer you to take action, such as opening an URL address. If you'd rather use the command line,you could install zbar-tools instead This article, along with any associated source code and files, is licensed under The Code Project Open License (CPOL) The contact information in the QR codes above are the same with the MeCard QR code having a smaller surface area or 'footprint', this is because of the internal data formating required to get the information in the correct format into the QR code

DelphiZXingQRCode: Delphi QR Code Generator DelphiZXingQRCode is a Delphi port of the QR Code functionality in ZXing, an open source barcode image processing library. The code was ported to Delphi by Senior Debenu Developer, Kevin Newman. The port retains the original Apache License (v2.0). Need to add QR barcodes t When coding in a QR code format, information is arranged horizontally and vertically using black squares against a white background inside a square grid. QR codes can hold a wide variety of data but its limit depends on the type of data being stored. If the input mode is only numeric for example, then a QR code can store up to 7,089 characters. Many QR codes are a mixture of input modes and will, therefore, have varying sizes and capacities.// Error correction // error correction low (7%) Encoder.ErrorCorrection = ErrorCorrection.L; // or // error correction medium (15%) The Default Encoder.ErrorCorrection = ErrorCorrection.M; // or // error correction quarter (25%) Encoder.ErrorCorrection = ErrorCorrection.Q; // or // error correction high (30%) Encoder.ErrorCorrection = ErrorCorrection.M; // module size in pixels (default is 2) Encoder.ModuleSize = 2; // Quiet zone around the symbol (default is 8) // Quiet zone must be at least 4 times the module size Encoder.QuietZone = 8; // ECI Assignment Value (default is -1 not used) // The ECI value is a number in the range of 0 to 999999. // or -1 if it is not used Encoder.ECIAssignValue = -1; Higher error correction percentage gives you better protection against damaged QR Code images. The cost is the size of the QR symbol. A great way to use QR codes is with plain text, whether it's a simple message to share, the answers to a quiz or exam, or clues for a treasure hunt, QRStuff.com has all of your text QR code needs covered with our Plain Text data type - and ours are FREE and don't expire
