ITEXT5 Font with 'Identity-H' is not recognized.问题解决

用 itextsharp 制作PDF文件的时候发生错误

Font 'd:\SIMSUN.TTC' with 'Identity-H' is not recognized.

原本是 

BaseFont baseFT = BaseFont.CreateFont("d:\SIMSUN.TTC", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

应修改为： 

 BaseFont baseFT = BaseFont.CreateFont("d:\SIMSUN.TTC,1", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

在字体路径的后面加了一个“,0”解决了，虽然不知道为什么，但是猜测这个是字体组有关，因为雅黑有三种，常规、加粗、极细
