Simple "puzzle" implementation1. Free to display more than one picture, each free to move, rotate, zoom2. JSON-based graphical location parameter storage3. Position parameters can be recorded after manual placement to fileMaybe:1. Add a gradient animation when switching graphics positions2. The current input is an absolute number of parameters, no relative to the width of the mobile phone, the latter is intact...Welcome to join us to enrich some inter
Today, the reason for the release of this article is a user requirements, is to achieve the local picture sliding guide effect. This effect is generally common on news clients, and its functions are:
