以编程方式在Word文档中布局图像

Question

我正在尝试通过我在WPF中编码的应用程序生成word文档。在该文档中，我还需要布置一些图像以及标题，如下图所示。

所有图像都作为base64字符串存储在数据库中。我能够将图像作为“BitmapImage”对象加载到文档中，但不确定如何布局图像，如图所示。用于加载文档中图像的代码片段如下：

        var bookmarks = wordDoc.Bookmarks;
        var range = bookmarks["ExternalImage"].Range;
        foreach (var image in ExternalImages) // here image is "BitmapImage" object
        {
            float scaleHeight = (float)250 / (float)image.Image.PixelHeight;
            float scaleWidth = (float)250 / (float)image.Image.PixelWidth;
            var min = Math.Min(scaleHeight, scaleWidth);
            var bitmap = new TransformedBitmap(image, new ScaleTransform(min, min));   
            System.Windows.Clipboard.SetImage(bitmap);
            range.Paste();
        }

我需要有关如何布局图像的帮助，如上图所示以及标题。请注意，我不是从文件加载图像而是从内存对象加载图像。

谢谢，

根据@CindyMeister在评论中提供的方向，以下是使用代码布局图像的工作代码片段：

    imageTable = wordDoc.Tables.Add(sel.Range, rows, cols, ref oMissing, ref oMissing);
    imageTable.AllowAutoFit = true;
    row = 1; col = 1;
    foreach (var image in Images)
   {
      float scaleHeight = (float)475 / (float)image.PixelHeight;   
     // here 475 is approx image size I want in word document
     float scaleWidth = (float)475 / (float)image.PixelWidth;
     var min = Math.Min(scaleHeight, scaleWidth);

     var bitmap = new TransformedBitmap(image, new ScaleTransform(min, min));

     System.Windows.Clipboard.SetImage(bitmap);

     //more efficient/faster in C# if you don't "drill down" multiple times to get an object
     Word.Cell cel = imageTable.Cell(row, col);
     Word.Range rngCell = cel.Range;
     Word.Range rngTable = imageTable.Range;

     rngCell.Paste();
     cel.VerticalAlignment = WdCellVerticalAlignment.wdCellAlignVerticalCenter;
     rngCell.ParagraphFormat.Alignment = WdParagraphAlignment.wdAlignParagraphCenter; 
     // set caption below image
     rngTable.ParagraphFormat.SpaceAfter = 6;
     rngCell.InsertAfter(image.Caption);
     rngTable.Font.Name = "Arial Bold";
     row++;
  }

这个代码我发布仅供参考，让人们有一些起点。欢迎任何建议。
