In my previous article, I shared how to use PyQt and Dynamsoft Barcode Reader to create a simple Windows-styled GUI app to read barcodes from image files. Now I am going to add a little bit more code to scan barcodes from the webcam video stream.
Qt for Python enables developers to quickly create GUI apps on Windows, Linux and macOS with one codebase. In this article, I will share how to build a Python barcode reader with Qt on Windows. Since Dynamsoft Barcode Reader SDK is also cross-platform, it is easy for you to reuse the sample code on Linux and macOS.
