這篇文章主要為大家詳細(xì)介紹了如何使用C#實現(xiàn)Word加蓋的騎縫章效果,文中的示例代碼講解詳細(xì),具有一定的借鑒價值,有需要的小伙伴可以參考下
實現(xiàn)效果
在OA的自動化處理系統(tǒng)中，通過審批的最終節(jié)點，可能會對WORD文件加蓋電子章，比如定位帶有指定文字的Range周圍加蓋電子章，騎縫章，甚至水印圖片。比如如下效果圖：
范例運(yùn)行環(huán)境
操作系統(tǒng)： Windows Server 2019 DataCenter
操作系統(tǒng)上安裝 Office Word 2016 ，客戶端使用的 Office Word 2019
.net版本： .netFramework4.7.1 或以上
開發(fā)工具：VS2019 C#
Office DCOM 配置
請參考我的文章《C# 讀取Word表格到DataSet》有對Office DCOM詳細(xì)配置介紹，這里不再贅述。
設(shè)計實現(xiàn)
創(chuàng)建stamp圖章類
導(dǎo)出WORD文件可以傳入多個圖章類（如果需要的話），圖章類主要包括實現(xiàn)如下設(shè)置：
1、可設(shè)置三種圖片（標(biāo)準(zhǔn)的蓋章圖片、騎縫章圖片、水印圖片）
2、標(biāo)準(zhǔn)的蓋章圖片是否顯示，不顯示則可以只顯示騎縫章或水印圖片，這個可以模擬多次蓋騎縫章的效果
3、定位蓋章文字，可以設(shè)置一下 x、y的偏移量，以校準(zhǔn)指定的模板文件，達(dá)到最佳重疊效果。
4、可設(shè)置各種章的翻轉(zhuǎn)角度（可隨機(jī)選?。?/p>
示例代碼如下：
public class stamp
{
public string stampImageFilename = ""; //蓋章圖片
public string stampImageFilename2 = ""; //騎縫章圖片
public string stampImageFilename3 = ""; //水印章圖片
public bool stampImageVisible = true; //主章是否可顯示
public string findWord = ""; //查找蓋章定位文字
public int findWordOffsetX = 0; //查找蓋章文字后，章的定位偏移量
public int findWordOffsetY = 0; //查找蓋章文字后，章的定位偏移量
public int stamp2X = 0; //騎縫章偏移量
public int stamp2Y = 0; //騎縫章偏移量
public int roteAngle = 0; //騎縫章翻轉(zhuǎn)角度，12點方向為0度，順時針計算角度
public bool roteReFix = false; //騎縫章翻轉(zhuǎn)角度重新計算適應(yīng)圖片（多見于對角線）
public bool randomRoteAngle = false; //騎縫章是否按指定角度的最大隨機(jī)值提取
public int stampImageWidth = 0; //章寬度
public int stampImageHeight = 0; //章高度
public string stamp2Direction = "right"; //騎縫章蓋章方向 默認(rèn)right ，包括 left/top/bottom
public int stampAngle = 0; //騎縫章翻轉(zhuǎn)角度，12點方向為0度，順時針計算角度
public bool randomStampAngle = false; //騎縫章是否按指定角度的最大隨機(jī)值提取
public int stamp3X = 0; //水印章每頁X
public int stamp3Y = 0; //水印章每頁Y
public int stamp3Angle = 0; //水印章翻轉(zhuǎn)角度，12點方向為0度，順時針計算角度
}電子章圖片的計算與定位
可以創(chuàng)建多個圖章類添加 ArrayList 中進(jìn)行方法傳遞， 初始值為public ArrayList Stamps = null;
創(chuàng)建方法 public string setWordStamps(string _filename,ArrayList Stamps)
實現(xiàn)的功能大致如下：
1、主章根據(jù)提供查找的關(guān)鍵字，如 “蓋章處：”、“蓋章：”，然后添加圖片重疊在文字的上方周圍
2、騎縫章根據(jù)頁數(shù)進(jìn)行分割計算，每頁分隔寬度不小于 1 像素
3、騎縫章可選擇“蓋”在頁面的上下左右位置，如果多個位置方向都需要“蓋”，則傳遞多個 stamp 圖章類
4、章可以隨機(jī)和指定旋轉(zhuǎn)角度

以上是實現(xiàn)設(shè)計的一些參考代碼，在實際的使用中，可能還會遇到如下問題：
1、定位關(guān)鍵字的疊加效果不好，因此針對每一個模板文件均需要調(diào)整圖片的x、y偏移量，以達(dá)到最佳效果
2、對于超多頁面的文件(如幾萬頁)，騎縫的效果可能不佳，可以采取調(diào)整圖片像素寬度，或拆分模板文件進(jìn)行處理
