Here is a brief introduction to the Zxing library. Zxing is an open source, Java-implemented 1d/2d barcode image processing library, which contains ports that are contacted in other languages. Zxing can achieve the use of mobile phone's built-in camera to complete the barcode scanning and decoding. The project can be implemented by barcode coding and decoding. The following formats are currently supported: UPC-A,UPC-E, EAN-8,

Brief IntroductionThe recent widget project used a camera to process barcodes, and Zhang Shi recommended zxing, a source project, and did a simple research.Zxing is an open source Java class Library for parsing 1d/2d barcodes in multiple formats. The goal is to decode the QR code, Data Matrix, UPC 1D Barcode. It provides clients under a variety of platforms including: J2ME, J2SE, and Android.Currently, zxing mainly supports the following barcodes:bull; Upc-a and UPC-Ebull;

The world's information is everywhere, and bar code is pervasive. Easy and fast generation and reading of bar code information has become a basic function of smartphones. How Can I scan the bar code in the window phone app? The first thing that comes to mind is to use a camera to read bar code images, binarization, and image processing. But as the saying goes, don't reinvent the wheel. Thanks to the powerful zxing Library [1], we can focus more on the implementation of the app's own functions. T
