Recently work needs to generate share pictures, initially with JS Html2canvas plug-in various problems, and then simply PHP PG Library in the background to generate pictures, very happy to solve the various problems, we want to achieve the effect such as:

Assume that the resource folder used in the code is under the current Code_png directory:
