看了一片文章(http://keleyi.com/a/bjac/nurox416.htm),是使用分型画树叶,代码是Java的,因为Java很久没弄了,改用C#实现,下载地址:
画树叶小程序下载
核心代码:
public void PaintKeleyiLeaf(Graphics g) { Random k_r = new Random(); int i; double x = 0, y = 0, r, u = 0; for (i = 0; i <= 100000; i++) { r = (int)(k_r.NextDouble() * 100); if (r < 1) { x = 0; y = .16 * y; } if (r >= 1 && r < 86) { u = .85 * x + .04 * y; y = -0.04 * x + 0.85 * y + 1.6; x = u; } if (r >= 86 && r < 97) { u = .2 * x - .26 * y; y = .23 * x + .22 * y + 1.6; x = u; } if (r >= 97) { u = -.15 * x + .28 * y; y = 0.26 * x + .24 * y + .44; x = u; } g.DrawString(".", keleyifont, Brushes.Green, (int)(40 * x + 120), (int)(420 - 40 * y)); } g.DrawString("keleyi.com", keleyifont, Brushes.Red, 50, 100); }
其中keleyifont请参考:http://keleyi.com/a/bjac/d88s8cyv.htm
