--Updated to provide full working class example, with 2 sample documents--
www.sklinar.co.uk/wp-content/uploads/mydoc.docx - Original Document with a INCLUDETEXT instruction to merge in Footer.Docx
www.sklinar.co.uk/wp-content/uploads/footer.docx
I have added a ImagePart to my document as well as using FeedData() to supply it with streamed content.
But all I can get to appear in my document is a red box.
My initial code Creates a Run with a Drawing as it's child:
--For this example, I've used a hard-coded FileStream to weed out dodgy images--
Just to get this working, I am using the same footer each time, and this is currently hard-coded with the correct footer:
runToAmend.InsertAfterSelf(CreateImageRun(sourceDocument,run,target.MainDocumentPart.FooterParts.ElementAt(2)));
The runToAmend is taken from a run in the current document - which holds a field which is then removed and the picture (and other text taken from another document) placed in it's place.
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(
new DW.Inline(
new DW.Extent() { Cx = 990000L, Cy = 792000L },
new DW.EffectExtent()
{
LeftEdge = 0L,
TopEdge = 0L,
RightEdge = 0L,
BottomEdge = 0L
},
new DW.DocProperties()
{
Id = (UInt32Value)1U,
Name = "Picture 1"
},
new DW.NonVisualGraphicFrameDrawingProperties(
new A.GraphicFrameLocks() { NoChangeAspect = true }),
new A.Graphic(

new A.Blip(

{

})
)
{
Embed = relationshipId,
CompressionState =
A.BlipCompressionValues.Print
},
new A.Stretch(
new A.FillRectangle())),
new PIC.ShapeProperties(
new A.Transform2D(
new A.Offset() { X = 0L, Y = 0L },
new A.Extents() { Cx = 990000L, Cy = 792000L }),
new A.PresetGeometry(
new A.AdjustValueList()
) { Preset = A.ShapeTypeValues.Rectangle }))
) { Uri = "http://schemas.openxmlformats.org/drawingml/2006/picture" })
)
{
DistanceFromTop = (UInt32Value)0U,
DistanceFromBottom = (UInt32Value)0U,
DistanceFromLeft = (UInt32Value)0U,
DistanceFromRight = (UInt32Value)0U,
EditId = "50D07946"
});
}
The XML produced appears correct, and the image gets added to the /Media/ folder.

回答1:
I've analyzed your word document. There are a few issues with your word document:
If I try to open your word document in the MS productivity toolkit I get the error message "Root element is missing".
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<Paragraph>().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<Run>(), 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<PIC.Picture>().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<A.Blip>().FirstOrDefault();
ImagePart p = sourceDoc.MainDocumentPart.GetPartById(shape.Embed.Value) as ImagePart;
With theses changes the image appears in the mydoc.docx word document.
