gremlin drawing

Join us today to learn about a lightweight class library that implements the SVG path stroke drawing and animation, we introduce the segment from easy to use, detailed usage, resources and cases, and source code interpretation.1. Easy to get started Add segment to the HTML aspect to define path. JS uses path to instantiate a segment, then you can use the segment draw method. var MyPath = document.getElementById ("My-path"), segment = new segme

BodyThe headline is a bit scary, but drawRect the evaluation is not too much. In the development of weekdays, the random coverage drawRect method, a little careless will make your program memory burst. Let's look at an example below.Do an artboard function, but suffer from memory problems have not been solved. The artboard function is simple, which is to record the track of your finger touch and then draw it on the screen. Let's take a look at the following:We see the state of the left memory de
