Comparison of open-source tools for generating QR codes (with source code), comparison of open-source tools with source code One day, zxing was found to be slow. As a result, it was found that there were three common open-source tools: Zxing (zxing. dll) ThoughtWorks (ThoughtWorks. QRCode. dll) QrCodeNet (Gma. QrCodeNet. Encoding. dll) Which one is better?
