谁手头上有swf文件结构分析的资料阿！

最近了解一下swf scanner
不知道那位仁兄有swf文件分析这方面的资料
给个链接或者是一个mail

在这谢先

With the number of Web sites using Macromedia Flash Files (.swf files) to present content, as a Web developer it may come in handy to have an ASP page that could easily read various tidbits of information about a Flash file. Fortunately, Flash files save a plethora of useful information in their headers. This information can be read using the FileSystemObject through an ASP page! (To learn more about Flash, check out FlashKit.com!)

In order to ease the process of reading this information, I created a handy class to do the grunt work for me. (For more information on using classes with VBScript, be sure to read: Using Classes within VBScript.) The class I created returns the following information about a Flash file:

SWFDump Class
Property Description
Version The version of the Flash file (3,4 or 5 at the moment)
Height Expresed in pixels.
Width Expresed in pixels.
xMin Expresed in Twips (20 twips = 1 pixel)
xMax Expresed in Twips
yMin Expresed in Twips
yMax Expresed in Twips
FileSize The total size of the .swf file.
FrameRate How many frames are in the Flash file.
FrameCounter Frame counter information.


The use of the SWFDump class is very simple. First off, I recommend that you place it in an include file so that you can easily include the class in the files that need to read Flash file information. (For more information on server-side includes be sure to read: The Low-Down on #include.) I chose to name my include file swfheaderdump.inc. To use the class, simply use code like the following:

<!-- #include file="swfheaderdump.inc" -->

Simple enough. The file swfheaderdump.inc needs to contain the full definition of the SWFDump class:

文件的版本和电影的高宽等信息用flash控件直接就可以分析出来
但是要分希swf文件里面的元素还不知道怎么办，比如：脚本等
