实现效果

在OA的自动化处理系统中，通过审批的最终节点，可能会对WORD文件加盖电子章，比如定位带有指定文字的Range周围加盖电子章，骑缝章，甚至水印图片。比如如下效果图：

范例运行环境

操作系统： Windows Server 2019 DataCenter

操作系统上安装 Office Word 2016 ，客户端使用的 Office Word 2019

.net版本： .netFramework4.7.1 或以上

开发工具：VS2019  C#

Office DCOM 配置

请参考我的文章《C# 读取Word表格到DataSet》有对Office DCOM详细配置介绍，这里不再赘述。 

设计实现

创建stamp图章类 

导出WORD文件可以传入多个图章类（如果需要的话），图章类主要包括实现如下设置：

1、可设置三种图片（标准的盖章图片、骑缝章图片、水印图片）

2、标准的盖章图片是否显示，不显示则可以只显示骑缝章或水印图片，这个可以模拟多次盖骑缝章的效果

3、定位盖章文字，可以设置一下 x、y的偏移量，以校准指定的模板文件，达到最佳重叠效果。

4、可设置各种章的翻转角度（可随机选取）

示例代码如下： 

public class stamp
        {
            public string stampImageFilename = "";  //盖章图片
            public string stampImageFilename2 = "";  //骑缝章图片
            public string stampImageFilename3 = "";  //水印章图片
            public bool stampImageVisible = true;  //主章是否可显示
            public string findWord = "";   //查找盖章定位文字
            public int findWordOffsetX = 0; //查找盖章文字后，章的定位偏移量
            public int findWordOffsetY = 0; //查找盖章文字后，章的定位偏移量
            public int stamp2X = 0; //骑缝章偏移量
            public int stamp2Y = 0; //骑缝章偏移量
            public int roteAngle = 0; //骑缝章翻转角度，12点方向为0度，顺时针计算角度
            public bool roteReFix = false; //骑缝章翻转角度重新计算适应图片（多见于对角线）
            public bool randomRoteAngle = false; //骑缝章是否按指定角度的最大随机值提取
            public int stampImageWidth = 0; //章宽度
            public int stampImageHeight = 0; //章高度
            public string stamp2Direction = "right";  //骑缝章盖章方向 默认right ，包括 left/top/bottom

            public int stampAngle = 0; //骑缝章翻转角度，12点方向为0度，顺时针计算角度
            public bool randomStampAngle = false; //骑缝章是否按指定角度的最大随机值提取

            public int stamp3X = 0; //水印章每页X
            public int stamp3Y = 0; //水印章每页Y
            public int stamp3Angle = 0; //水印章翻转角度，12点方向为0度，顺时针计算角度


        }

电子章图片的计算与定位

可以创建多个图章类添加 ArrayList 中进行方法传递， 初始值为public ArrayList Stamps = null;

创建方法  public string setWordStamps(string _filename,ArrayList Stamps)

实现的功能大致如下：

1、主章根据提供查找的关键字，如 “盖章处：”、“盖章：”，然后添加图片重叠在文字的上方周围

2、骑缝章根据页数进行分割计算，每页分隔宽度不小于 1 像素

3、骑缝章可选择“盖”在页面的上下左右位置，如果多个位置方向都需要“盖”，则传递多个 stamp 图章类

4、章可以随机和指定旋转角度

示例代码如下：

public string setWordStamps(string _filename,ArrayList Stamps){
            Object Nothing =System.Reflection.Missing.Value;
			string _file="",_path=Path.GetDirectoryName(_filename)+"\tempbfile\",_ext="";

			_file=Path.GetFileNameWithoutExtension(_filename);
			_ext=Path.GetExtension(_filename);
			string _validfilename=Guid.NewGuid().ToString()+_ext;
			string _lastfile=_path+_validfilename;
            string _pdfFile = _path + Guid.NewGuid().ToString() + ".pdf";

            System.IO.File.Copy(_filename,_lastfile,true);
			if(!File.Exists(_lastfile))
			{
				return "";
			}


            //取得Word文件保存路径
            object filename=_lastfile;
			//创建一个名为WordApp的组件对象
			Word.Application WordApp=new Word.Application();
            
			//创建一个名为WordDoc的文档对象
			WordApp.DisplayAlerts=Word.WdAlertLevel.wdAlertsNone;
			Word.Document WordDoc=WordApp.Documents.Open(ref filename,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing,ref Nothing);
            WordDoc.SpellingChecked = false;
            WordDoc.ShowSpellingErrors = false;
            WordDoc.ActiveWindow.View.Type = Word.WdViewType.wdNormalView;

//遍历stamp图章类
    foreach (stamp Stamp in Stamps)
    {
                    bool isfirst = true;
                    int iii = 0;
                    int selectStart = 0;
                    ArrayList restoreRange = new ArrayList();
                    while (true)
                    {
                        iii++;
                        bool findstamptext = false;
                        if (Stamp.findWord != "")
                        {

总结 

以上是实现设计的一些参考代码，在实际的使用中，可能还会遇到如下问题：

1、定位关键字的叠加效果不好，因此针对每一个模板文件均需要调整图片的x、y偏移量，以达到最佳效果

2、对于超多页面的文件(如几万页)，骑缝的效果可能不佳，可以采取调整图片像素宽度，或拆分模板文件进行处理

示例代码仅作参考，欢迎大家评论指教！
