介绍一个轻量级java的swf处理库

提取swf文件元信息、压缩swf、解压swf都可以处理，来自于http://www.brooksandrus.com/blog/category/java/，或者直接这里下载。

一个小例子：
Java代码

 SWFHeader header = new SWFHeader("G:\\mplayer\\test.swf");    System.out.println("signature:   " + header.getSignature());    System.out.println("version:     " + header.getVersion());    System.out.println("compression: " + header.getCompressionType());    System.out.println("size:        " + header.getSize());    System.out.println("nbits:       " + header.getNbits());    System.out.println("xmax:        " + header.getXmax());    System.out.println("ymax:        " + header.getYmax());    System.out.println("width:       " + header.getWidth());    System.out.println("height:      " + header.getHeight());    System.out.println("frameRate:   " + header.getFrameRate());    System.out.println("frameCount:  " + header.getFrameCount()); 

压缩、解压缩，需要注意生成的文件将覆盖原文件：
Java代码

    //压缩     SWFCompressor compressor=new SWFCompressor("G:\\test.swf");      //解压缩      SWFDecompressor decompressor=new SWFDecompressor("G:\\test.swf");  //压缩SWFCompressor compressor=new SWFCompressor("G:\\test.swf");//解压缩SWFDecompressor decompressor=new SWFDecompressor("G:\\test.swf");
