常见问题

问：像PS里的素描、浮雕、水彩等 一些高级滤镜效果如何制作，用在JPG上面的。求救了，各位大虾出手相助一下吧....

终极讨厌答：有这样的类包，但主要都是通过颜色矩阵滤镜和回旋滤镜结合实现的。

请先去http://www.flashtc.com/article.asp?articleid=1890 下载Flash8 滤镜下载完毕后解压，把那个“fl”文件夹复制到这里：C:\Program Files\Macromedia\Flash 8\zh_cn\First Run\Classes，然后就可以用as来调用了。我做了一些练习，熟悉了一下，效果真不错，挺丰富。

这是代码，留着自己查看，有兴趣的朋友可以看看，先别头晕，我是把很多滤镜都写在一起了，其实每个滤镜都是很短的代码。
