OpenXml入門---word裏面插入圖片

        下面介紹如何在word裏面插入圖片，順便小弟發現MSDN官網有完整的OpenXML教程，雖然是全英文的不過仍是頗有幫助的。

        Tips，原來摘抄代碼裏面沒有模板，在copy過來發現插入word中的圖片大小不同，咱們如何查找設置圖片大小帶代碼的那一塊，建議本身用在word裏面插入一張圖片，經過OpenXml Tools 反編譯出C#代碼，而後改變圖片的大小，再次反編譯。

使用byeond compare 【http://www.scootersoftware.com/ 下載地址】比較C#代碼，就會發現是由於new DW.Extent() { Cx = 990000L, Cy = 792000L}  是由於這段設置照成的。 之後其實不少地方均可以藉助OpenXml Tools反編譯來進行對比。查看設置樣式的屬性位置。
