新浪微博，美图秀秀还有其他的那些都是把滤镜的swf编译进了他的flex里面，不好取出，只有qq空间的是按需加载，点击一个滤镜，加载一个滤镜swf，所以qq空间，对不起了。。。
1.获取滤镜的swf，去qq空间的美化图片，点击一个滤镜，用firebug之类的得到滤镜，最后得到的滤镜：
"abao.swf","colorfulmood.swf","enhance.swf","lordkelvin.swf","blackenhance.swf","sweetjelly.swf","lightred.swf","aladin.swf","mellow.swf","rainbow.swf","romanticstar.swf","smokedval.swf","sweetlight.swf","sweet.swf","nashville.swf","lomored.swf"
对应的滤镜名称：
"阿宝色","缤纷心情","自动增强","枫叶","黑白画映","琥珀","亮红","潘多拉","午茶","彩虹","浪漫星光","掠影","甜美光影","甜美可人","往昔","晚秋"
2.用Loader类加载滤镜swf,对swf的content var a:BitmapData =content.execute(bmpData);bmpData 是目标图片的bitmapdata..那个execute方法是接口暴露出来渲染滤镜效果的方法，，qq空间美化图片里面美化和磨皮的swf也是用的类似方法。
其他都是些小细节，很简单的。
