word,excel,ppt轉Pdf,Pdf轉Swf,通過flexpaper+swftools實現在線預覽

• 其實這是我好幾年前的項目，現在再用這種方式我也不建議了，畢竟未來flash慢慢會淘汰，此方式也是因為目測大部分人都裝了flash，才這么做的，但是頁面展示效果也不好。其實還是考慮收費的控件，畢竟收費的還是做的不錯的！

而且此方式服務器要安裝office組件，項目實施也不好！

以上為最新更新建議！

 

• 自己上網查了好多種方法，最后還是選了這種不收費，還挺好用的方法

           為了用戶有一個好的體驗我將word、excel、ppt轉Pdf,Pdf轉Swf寫在服務上，因為我當時做的時候Pdf轉Swf會執行pdf2swf.exe彈出黑框，對用戶體驗不好，還有就是ppt轉swf時會有一個彈出框，提示正在發布，我沒搞明白，就把他們都寫在服務上了。
