By observation, the 360 installation of animation is a few rounds of continuous amplification process. That is, the concentric circle radius of different amplification. I use five circles to make a similar effect, in order to differentiate effects, I set five circles to use different brushes. The following are the specific code: This five radius is a global variable.int x1 = 200;int x2 = 100;int x3 = 50;int x4 = 150;int x5 = 250; The specific implementation is placed in the timer control X1
