Создание ImagePart не сохраняет отношения в OpenXML
- Обновлен, чтобы предоставить полный пример рабочего класса, с 2 примерами документов -
www.sklinar.co.uk/wp-content/uploads/mydoc.docx - Оригинальный документ с инструкцией INCLUDETEXT для объединения в Footer.Docx
www.sklinar.co.uk/wp-content/uploads/footer.docx
Я добавилImagePart к моему документу, а также с помощьюFeedData() обеспечить его потоковым контентом.
Но все, что я могу увидеть в своем документе, это красная рамка.
Мой исходный код СоздаетRun сDrawing как это ребенок
- В этом примере я использовал жестко закодированный FileStream, чтобы отсеять нечеткие изображения.
Просто чтобы заставить это работать, я использую один и тот же нижний колонтитул каждый раз, и в настоящее время он жестко задан с правильным нижним колонтитулом:
runToAmend.InsertAfterSelf(CreateImageRun(sourceDocument,run,target.MainDocumentPart.FooterParts.ElementAt(2)));
runToAmend берется из прогона в текущем документе, который содержит поле, которое затем удаляется, а изображение (и другой текст, взятый из другого документа) помещается на его место.
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 },

Созданный XML-файл выглядит правильно, и изображение добавляется в/Media/ папка.
