Creating an ImagePart isn't saving the Relationship in OpenXML

Answer 1

I've analyzed your word document. There are a few issues with your word document:

1. If I try to open your word document in the MS productivity toolkit I get the error message "Root element is missing".

2. If I open your document as a zip file (renaming to mergedfooter.zip) then in the footer2.xml.rels file the relationship for your image is missing. I think that's the reason you get the "red box".

To further analyze your problem I need the complete code (how do you get the FooterPart)?

Below you will find an example of how to insert an image into the footer of a word document. Please note, that the example below assumes that your word document already contains a footer and your footer contains a paragraph element.

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().FirstOrDefault();

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

EDIT:

After analyzing your newly provided documents:

The reason the releationship for your image is not saved is because you do not Dispose() or Close() your word document.

So, just add a using statement:

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

  mainDoc.MainDocumentPart.Document.Save();           
}

Furthermore in your ReplaceRunsWithRuns() method you must use PIC.Picture to reference the correct Picture class:

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

By the same token in your CreateImageRun() method I've changed the first three code lines:

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

With theses changes the image appears in the mydoc.docx word document.
