Beim Erstellen eines ImageParts wird die Beziehung nicht in OpenXML gespeichert
--Aktualisiert, um ein vollständiges Beispiel für die Arbeiterklasse mit 2 Beispieldokumenten bereitzustellen--
www.sklinar.co.uk/wp-content/uploads/mydoc.docx - Originaldokument mit einer INCLUDETEXT-Anweisung zum Zusammenführen in Footer.Docx
www.sklinar.co.uk/wp-content/uploads/footer.docx
Ich habe a hinzugefügtImagePart zu meinem Dokument sowie mitFeedData() um es mit gestreamten Inhalten zu versorgen.
Aber alles, was ich in meinem Dokument sehen kann, ist ein rotes Kästchen.
Mein anfänglicher Code Erstellt eineRun mit einerDrawing als Kind:
--Für dieses Beispiel habe ich einen fest codierten FileStream verwendet, um zwielichtige Bilder auszusortieren--
Um dies zum Laufen zu bringen, verwende ich jedes Mal die gleiche Fußzeile. Diese wird derzeit mit der richtigen Fußzeile hartcodiert:
runToAmend.InsertAfterSelf(CreateImageRun(sourceDocument,run,target.MainDocumentPart.FooterParts.ElementAt(2)));
DasrunToAmend wird aus einem Lauf im aktuellen Dokument entnommen - das ein Feld enthält, das dann entfernt und das Bild (und anderer Text aus einem anderen Dokument) an seiner Stelle platziert wird.
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 },

Das erzeugte XML wird korrekt angezeigt und das Bild wird dem hinzugefügt/Media/ Mappe.
