C#采取OpenXml給word外面拔出圖片

本文實例講述了C#采取OpenXml給word外面拔出圖片的辦法，分享給年夜家供年夜家參考。詳細剖析以下：

起首須要指出的是在MSDN官網有完全的OpenXML教程，固然是全英文的不外照樣很有贊助的。

注，本來摘抄代碼外面沒有模板，在copy過去發明拔出word中的圖片年夜小紛歧樣，我們若何查找設置圖片年夜小帶代碼的那一塊，建議本身用在word外面拔出一張圖片，經由過程OpenXml Tools 反編譯出C#代碼，然後轉變圖片的年夜小，再次反編譯。

應用byeond compare 【http://www.scootersoftware.com/ 下載地址】比擬C#代碼，就會發明是由於new DW.Extent() { Cx = 990000L, Cy = 792000L}  是由於這段設置形成的。今後其實許多處所都可以借助OpenXml Tools反編譯來停止比較。檢查設置款式的屬性地位。
