将word文档嵌入单个文档时如何使用文本创建图像

Question

我正在使用 System.IO.Packaging 和 Open XML SDK 创建一个新的 docx。在我的 docx 中，我想嵌入其他现有的 docx 文件。结果应该与我在 Microsoft Word 中手动执行的结果相同。每个嵌入的 docx 文件的 docx 中应该有一个图标。在图标中，我想添加嵌入的 docx 文件的名称。对于要嵌入的所有文件，我有相同的图像。但我不知道如何在嵌入时向图像添加一些文本。

这是我目前的代码：

   static void Main(string[] args)
{
  const string containingDocumentPath = @"ContainingDocument.docx";

  const string embeddedDocumentPath = @"EmbeddedDocument.docx";

  CreatePackage(containingDocumentPath, embeddedDocumentPath);
}

private static void CreatePackage(string containingDocumentPath, string embeddedDocumentPath)
{
  using (WordprocessingDocument package = WordprocessingDocument.Create(containingDocumentPath, WordprocessingDocumentType.Document))
  {
    AddParts(package, embeddedDocumentPath);
  }
}

private static void AddParts(WordprocessingDocument parent,
                             string embeddedDocumentPath)
{
  var mainDocumentPart = parent.AddMainDocumentPart();
  GenerateMainDocumentPart().Save(mainDocumentPart);

  var embeddedPackagePart =
    mainDocumentPart.AddNewPart<EmbeddedPackagePart>(
      "application/vnd.openxmlformats-" +
      "officedocument.wordprocessingml.document",
      "rId1");

  GenerateEmbeddedPackagePart(embeddedPackagePart, embeddedDocumentPath);

  var imagePart = mainDocumentPart.AddNewPart<ImagePart>("image/x-emf", "rId2");
  GenerateImagePart(imagePart);
}

private static Document GenerateMainDocumentPart()
{
  var element =
    new Document(
      new Body(
        new Paragraph(
          new Run(
            new EmbeddedObject(
              new Shape(
                new ImageData()
                  {
                    RelationshipId = "rId2",
                  }
                )
                {
                  Id = "_x0000_i1025",
                  OptionalString = "abc",
                  Style = "width:16pt;height:16pt",
                },
              new OleObject()
                {
                  ProgId = "Word.Document.12",
                  ShapeId = "_x0000_i1025",
                  ObjectId = "_1299573545",
                  Id = "rId1"
                }
              )
              {
                DxaOriginal = "1531UL",
                DyaOriginal = "991UL"
              }
            )
          )
        )
      );

  return element;
}

public static void GenerateEmbeddedPackagePart(OpenXmlPart part, string embeddedDocumentPath)
{
  byte[] embeddedDocumentBytes;

  // The following code will generate an exception if an invalid
  // filename is passed.
  using (FileStream fsEmbeddedDocument = File.OpenRead(embeddedDocumentPath))
  {
    embeddedDocumentBytes = new byte[fsEmbeddedDocument.Length];

    fsEmbeddedDocument.Read(embeddedDocumentBytes, 0, embeddedDocumentBytes.Length);
  }

  using (var writer = new BinaryWriter(part.GetStream()))
  {
    writer.Write(embeddedDocumentBytes);
    writer.Flush();
  }
}

public static void GenerateImagePart(OpenXmlPart part)
{
  using (var writer = new BinaryWriter(part.GetStream()))
  {
    writer.Write(File.ReadAllBytes(@"Icons\MyImage.GIF"));
    writer.Flush();
  }
}

    public static void GenerateEmbeddedIconPart(OpenXmlPart part, string filePath)
    {
        Byte[] image = GetIconBytes(filePath);
        using (var writer = new BinaryWriter(part.GetStream()))
        {
            writer.Write(image);
            writer.Flush();
        }
    }

    public static Byte[] GetIconBytes(string filePath)
    {
        System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(150, 60);
        bitmap.MakeTransparent();
        System.Drawing.Icon icon = System.Drawing.Icon.ExtractAssociatedIcon(filePath);
        System.Drawing.Font drawFont = new System.Drawing.Font("Arial", 8);
        System.Drawing.SolidBrush drawBrush = new System.Drawing.SolidBrush(System.Drawing.Color.Black);

        string drawText = Path.GetFileName(filePath);
        System.Drawing.Graphics graphics = System.Drawing.Graphics.FromImage(bitmap);
        graphics.Clear(System.Drawing.Color.White);
        graphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.SingleBitPerPixel;
        graphics.DrawIcon(icon, 20, 0);
        graphics.DrawString(drawText, drawFont, drawBrush, 0, 48);                      

        Byte[] data;
        using (var memoryStream = new MemoryStream())
        {
            bitmap.Save(memoryStream, System.Drawing.Imaging.ImageFormat.Bmp);
            data = memoryStream.ToArray();
        }

        drawFont.Dispose();
        drawBrush.Dispose();
        graphics.Dispose();
        return data;
    }
