点阵图变矢量的代码，有偿求改

shihaipeng05

一个很牛逼的变矢量算法。看似挺简单，不过本人不太会搞，先搬过来给高人研究研究。
这个画风还是挺独特的，都是线条描绘的明暗细节部分。不过代码里是同时好几条线一起画出来。不知道能不能搞成就1条线画完。求高人相助。


这个还算正常

调节参数可以搞各种画风。。。他们说这个叫阴猫画

还有各种风格，大家可以自己研究。http://www.openprocessing.org/还有很多有意思的代码，不过有很多是不能直接搬到processing上直接用的，不太兼容。只能在它网站上在线编译。      这些不重要，主要还是求单独一线画出来的代码。有意者M我。
