WASI is a modular system interface, which aims to build runnable .wasm modules for any WASI-compliant runtime, not only for Node.js and web browsers. Although WASI is still in development and not stable yet, it is available for some experimental projects. In this article, I will share how to use WASI SDK to build a .wasm barcode reader module by porting ZXing C++.Read more
ZXing is probably the most popular open source barcode SDK in the world. The library is written in Java and now has been ported to C++, .NET, Python, Objective-C, PHP and some other programming languages. Because ZXing is free, many developers would like to build barcode scanning apps with it. However, it is not competent for complicated business cases especially for images with multiple barcodes. In this article, I will show how to create a .NET barcode reader step by step and compare the performance difference between ZXing.Net and Dynamsoft Barcode Reader.
I saw many posts arguing the performance winner between open-source barcode SDKs – ZXing and ZBar. As an engineer, who is developing commercial barcode reader software for Dynamsoft, I am curious about which open source project is better, ZXing or ZBar? Considering ZXing is implemented in Java, whereas ZBar is implemented in C/C++. To fairly compare their performance, I decided to use JNI to wrap ZBar C/C++ source code and benchmark them in a Java program.
ZXing is an open-source, 1D/2D barcode image processing library implemented in Java. The supported barcode formats include UPC-A, UPC-E, EAN-8, Code 93, Code 128, QR Code, Data Matrix, Aztec, PDF 417, etc. Besides the Java version, developers can leverage other ported projects such as QZXing, zxing-cpp, zxing_cpp.rb, python-zxing and ZXing .NET to quickly make barcode reader or writer software. According to the visualization report of Google trends, QR code seems to be the most popular barcode format since 2009. In this post, I’d like to share how to use ZXing to create QR code writer and reader for both desktop Java applications and Android mobile apps.
Barcode scanning, especially QR code scans, are now widely used in various applications. This includes advertisements, newspapers, social networks, signage, and so on. The growth of QR codes is in large part due to the smartphone market’s booming growth. As a result, scanning technology tends to be more and more useful and important to businesses and consumers. In this article, we will take a glimpse on how to implement a simple barcode scan application on the Android platform.
