Aspose.Word出Word文档中嵌入的对象，如图片gif,jpg,png,txt,html等内容

示列1：

在C#中操作word，使用aspose.words这个控件是很方便的，也能用它来导出嵌入在word文档中的OLE对象(gif,jpg,png,txt,html等内容)。

代码如下

       public void ExtractImg()
         {
             Document doc = new Document(@ "c:\test.doc");

             //取得对象集合 
             NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true); 

             int i = 0; 

             foreach (Shape shape in shapes) 
             { 
                 if (shape.OleFormat != null) 
                 { 
                     //生成文件名 
                     string name = @ "c:\obj_" + shape.OleFormat.ProgId + i.ToString();

                     //判断OLE格式是否为Package(包) 
                     if (shape.OleFormat.ProgId == "Package")
                     { 
                         MemoryStream strm = new MemoryStream(); 
                         shape.OleFormat.Save(strm); 

                         try 
                         { 
                             //保存图片 
                             Bitmap img = (Bitmap)Bitmap.FromStream(strm); 
                             img.Save(name + ".png", ImageFormat.Png);
                         } 
                         catch 
                         { 
                             Stream file = new FileStream(name + ".object", FileMode.Create);
                             strm.WriteTo(file); 
                         } 
                     } 
                     i++; 
                 } 
             } 
         }

读取文档中图片并保存的方法如下：
NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true, false);
foreach (Shape shape in shapes)
{
if (shape.IsImage)
{
shape.Height = 100;
shape.ImageData.Save("");
shape.Remove();
}
}
插入图片的方法如下：

   DocumentBuilder builder = new DocumentBuilder();
   builder.InsertImage(" ")

示例3:

// Load the word document
Document wordDocument = new Document("Invitation.doc");
// get all the shapes
NodeCollection shapes = wordDocument.GetChildNodes(NodeType.Shape, true, false);
// loop through all the shapes
foreach (Shape shape in shapes)
{
    // check if it has an image
    if (shape.HasImage)
    {
        // save the image in memory stream
        MemoryStream imgStream = new MemoryStream();
        shape.ImageData.Save(imgStream);
  
        // recognize the barcode from the image stream above
        BarCodeReader reader = new BarCodeReader(new Bitmap(imgStream), BarCodeReadType.Code39Standard);
        while(reader.Read())
        {
            Console.WriteLine("Codetext found: "+ reader.GetCodeText());
        }
        // close the reader
        reader.Close();
    }

其它例子：

我要做一个试题导入程序，现在使用aspose.words能获取表格中的文本，图片，但就是不知道怎么获得图片在文本中的位置。想通过这个来生成一个html字符串，代码如下：

private void ViewNodeListImg()
        {
            Document doc = new Document("E:\\3-学习与培训\\2－程序学习\\读取Word图片项目\\WordImgTest\\WordImgTest\\upload\\test.doc");
            Aspose.Words.Tables.Table table = (Aspose.Words.Tables.Table)doc.GetChild(NodeType.Table, 0, true);
            string MyDir = "E:\\3-学习与培训\\2－程序学习\\读取Word图片项目\\WordImgTest\\WordImgTest\\upload\\img\\";
            int imageIndex = 0;
            string str = "";
            str += "<table>";
            // Iterate through all rows in the table.
            foreach (Row row in table.Rows)
            {
                str += "<tr>";
                // Iterate through all cells in the table.
                foreach (Cell cell in row.Cells)
                {
                    str += "<td>";
                    str +="<p>"+cell.Paragraphs.ToArray()[0].ToTxt()+"</p>";
                    NodeCollection shapes = cell.GetChildNodes(NodeType.Shape, true, false);
                    foreach (Shape shape in shapes)
                    {
                        //str += shape.Range;
                        if (shape.HasImage)
                        {
                            string imageFileName = string.Format(

                                "Image.ExportImages.{0} Out{1}", imageIndex, FileFormatUtil.ImageTypeToExtension(shape.ImageData.ImageType));

                            shape.ImageData.Save(MyDir + imageFileName);
                            imageIndex++;

                        }
                    }
                    str += "</td>";
                }
                str += "</tr>";
            }
            Response.Write(str);
        }
