如何在將Word文檔嵌入到單個文檔中時使用文本創建圖像

Question

我正在使用System.IO.Packaging和Open XML SDK創建新的docx。在我的docx中，我想嵌入其他現有的docx文件。結果應該與我在Microsoft Word中手動完成的結果相同。每個嵌入式docx文件的docx中應該有一個圖標。在圖標中，我想添加嵌入式docx文件的名稱。對於要嵌入的所有文件，我擁有相同的圖像。但我不知道如何在嵌入時向圖片添加一些文字。

這是我到目前爲止的代碼：

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; 
    }
