可能对你有帮助

Answer 5

又仔细看了下，iTextSharp的标准例子程序里的第7章有你要的东西Chap0707 chap0708（Chapter 7 example 8: HTML and CSS），我想几个例子结合研究下应该可以满足你的要求。

Answer 6

我也没做过，具体的不是很清楚，但是http://threebit.net/mail-archive/itext-questions/msg01033.html这个是一个html 2 pdf的例子，我还试验了下，效果还不错，不过不能处理css，但是css处理iTextSharp的标准例子程序里的第7章有你要的东西Chap0707 chap0708（Chapter 7 example 8: HTML and CSS）里边有，所以让你结合看一下，我也没弄过，我就不帮你仔细研究了。
只能给你提示，反正目前看下来，itextsharp功能还是比较强大的，另外推荐一个强人的blog给你http://www.cnblogs.com/hardrock/default.html?page=1，这个人应该是IText中国这边的最主要代表人物
