word,excel,ppt转Pdf,Pdf转Swf,通过flexpaper+swftools实现在线预览

• 其实这是我好几年前的项目，现在再用这种方式我也不建议了，毕竟未来flash慢慢会淘汰，此方式也是因为目测大部分人都装了flash，才这么做的，但是页面展示效果也不好。其实还是考虑收费的控件，毕竟收费的还是做的不错的！

而且此方式服务器要安装office组件，项目实施也不好！

以上为最新更新建议！

• 自己上网查了好多种方法，最后还是选了这种不收费，还挺好用的方法

           为了用户有一个好的体验我将word、excel、ppt转Pdf,Pdf转Swf写在服务上，因为我当时做的时候Pdf转Swf会执行pdf2swf.exe弹出黑框，对用户体验不好，还有就是ppt转swf时会有一个弹出框，提示正在发布，我没搞明白，就把他们都写在服务上了。
