制作火焰文字的演示，运行时文字周围有火焰闪动，颇为好看。基本思想：对于给定的文字，其周围的三原色分量值往外依次减去一个随机量（该随机量随时间改变，造成动画效果），直到减到0为止。在文字周围即可看到比文字颜色淡的火焰。如果忽略蓝色分量，并使黄色分量减的快一些，即可得到真实的火焰效果。-Flame text produced a demonstration, run-time text have flames around the flashing, rather good-looking. The basic idea: For a given text, the three primary colors of its surrounding points followed by less money out of a random quantity (the random amount of change over time, resulting in animation), until reduced to 0 so far. In the text around to see the text color than the lighter flame. If you ignore the weight of blue and yellow sub-minus the faster you will get a real flame effect.
