创建 ImagePart 并不将关系保存在 OpenXML 中

--更新以提供完整的工人阶级示例，以及 2 个示例文档--

www.sklinar.co.uk/wp-content/uploads/mydoc.docx- 原始文档包含 INCLUDETEXT 指令以合并到 Footer.Docx 中

www.sklinar.co.uk/wp-content/uploads/footer.docx

我添加了一个ImagePart到我的文档以及使用FeedData()为其提供流媒体内容。

但我能在我的文档中看到的只是一个红色框。

我的初始代码创建了一个Run with a Drawing因为它是孩子：

--对于这个例子，我使用了硬编码的 FileStream 来清除可疑的图像--

为了使其正常工作，我每次都使用相同的页脚，并且当前使用正确的页脚进行硬编码：

runToAmend.InsertAfterSelf(CreateImageRun(sourceDocument,run,target.MainDocumentPart.FooterParts.ElementAt(2)));

The runToAmend取自当前文档中的运行 - 它包含一个字段，然后将其删除，并将图片（以及从另一个文档中获取的其他文本）放置在其位置。

    public Run CreateImageRun(WordprocessingDocument sourceDoc,  Run sourceRunFromOriginalDocument, FooterPart footerPart)
    {
        ImageData shape = sourceRun.Descendants<ImageData>().FirstOrDefault();

        ImagePart p = sourceDoc.MainDocumentPart.GetPartById(shape.RelationshipId) as ImagePart;

        ImagePart newPart = footerPart.AddImagePart(ImagePartType.Jpeg);

        using (Stream stream = new FileStream(@"C:\Users\SAS\Desktop\IMG_20130803_104521.jpg",FileMode.Open,FileAccess.Read))
        {
            stream.Position = 0;
            newPart.FeedData(stream);
        }

        string partId = footerPart.GetIdOfPart(newPart);

        Drawing newImage = CreateImage(partId);
        return new Run(newImage);
    }

Code to Create Drawing

private Drawing CreateImage(string relationshipId)
    {
        // Define the reference of the image.
        return new Drawing(

我已经分析了你的word文档。您的word文档存在一些问题：

1. 如果我尝试在 MS 生产力工具包中打开您的 Word 文档，则会收到错误消息 消息“根元素丢失”。

2. 如果我将您的文档作为 zip 文件打开（重命名为 mergedfooter.zip），那么 在里面页脚2.xml.rels文件您的图像的关系丢失。 我认为这就是你得到“红框”的原因。

为了进一步分析您的问题，我需要完整的代码（您如何获得FooterPart)?

下面您将找到如何将图像插入 Word 文档页脚的示例。 请注意，下面的示例假设您的 Word 文档已包含页脚并且页脚包含段落元素。

using (WordprocessingDocument wordprocessingDocument = WordprocessingDocument.Open("mydoc.docx", true))
{
  MainDocumentPart mainPart = wordprocessingDocument.MainDocumentPart;

  // Search for your footer part here.
  // Just for the sake of simplicity I take the second footer part.
  FooterPart fp = mainPart.FooterParts.ToList()[2];                

  // Create new image part.
  ImagePart ip = fp.AddImagePart(ImagePartType.Jpeg);

  using (FileStream fs = File.Open("mypicture.jpg", FileMode.Open))
  {         
    ip.FeedData(fs);         
  }

  string relationshipId = fp.GetIdOfPart(ip);

  // Create the image element using your function.
  Drawing img = CreateImage(relationshipId);

  Run r = new Run(img);

  Paragraph para = fp.RootElement.Descendants<Paragraph>().FirstOrDefault();

  if(para != null)
  {
    para.Append(r);   
  }      
  else
  {
    Console.WriteLine("paragraph is null...");
  }
}

EDIT:

分析您新提供的文件后：

未保存图像关系的原因是 因为你不Dispose() or Close()你的word文档。

因此，只需添加一条 using 语句：

using (WordprocessingDocument mainDoc = WordprocessingDocument.Open("mydoc.docx", true))
{
  foreach (var item in mainDoc.MainDocumentPart.FooterParts)
  {
    ProcessParaIncludeTextMerge(item, item.Footer.Descendants<Run>(), mainDoc);
    item.Footer.Save();
  }

  mainDoc.MainDocumentPart.Document.Save();           
}

此外在你的ReplaceRunsWithRuns()你必须使用的方法PIC.Picture来参考正确的Picture class:

foreach (var item in value)
{
  if (!item.Descendants<PIC.Picture>().Any())
  {
    p.Append(item.CloneNode(true));
  }
  else
  {
    p.Append(CreateImageRun(source, item, target, f));
  }
}

同样的道理，在你的CreateImageRun()我改变的方法 前三行代码：

ImagePart newPart = footerPart.AddImagePart(ImagePartType.Jpeg);                   
A.Blip shape = sourceRun.Descendants<A.Blip>().FirstOrDefault();
ImagePart p = sourceDoc.MainDocumentPart.GetPartById(shape.Embed.Value) as ImagePart;

通过这些更改，图像出现在mydoc.docx字文档。
