OpenXml入门---word里面插入图片

下面介绍如何在word里面插入图片，顺便小弟发现MSDN官网有完整的OpenXML教程，虽然是全英文的不过还是很有帮助的。

Tips，原来摘抄代码里面没有模板，在copy过来发现插入word中的图片大小不一样，我们如何查找设置图片大小带代码的那一块，建议自己用在word里面插入一张图片，通过OpenXml Tools 反编译出C#代码，然后改变图片的大小，再次反编译。

使用byeond compare 【http://www.scootersoftware.com/ 下载地址】比较C#代码，就会发现是因为new DW.Extent() { Cx = 990000L, Cy = 792000L}  是因为这段设置照成的。 以后其实很多地方都可以借助OpenXml Tools反编译来进行对比。查看设置样式的属性位置。
