SVG (Scalable Vector Graphics). Next we will introduce how to determine whether the browser supports SVG. For more information, see, I hope this code will help you with Scalable Vector Graphics (SVG). It is based on the Extensible Markup Language (XML) and is used to describe two-dimensional Vector Graphics.

I tried the QR code scanning software on my Android mobile phone over the weekend and scanned my train tickets, business cards, and so on. It was very nice and interesting. Of course, Java can also implement this. Now I will share how to simply use Java to implement the encoding and decoding of QRCode In the QR code (w
