Hello,

Thanks for your inquiry.
please refer to the following code to meet your requirement.

Code: Select all

            Document doc = new Document();
            doc.LoadFromFile(@"Template.docx");

            Image newImage = Image.FromFile(@"E-iceblue.png");
            DocPicture newPic = new DocPicture(doc);
            newPic.LoadImage(newImage);

            Section section = doc.Sections[0];
            HeaderFooter header = section.HeadersFooters.Header;

            foreach (Paragraph para in header.Paragraphs)
            {
                List<DocumentObject> pictures = new List<DocumentObject>();
               

                //Get all pictures in the header
                foreach (DocumentObject docObj in para.ChildObjects)
                {
                    if (docObj.DocumentObjectType == DocumentObjectType.Picture)
                    {
                        pictures.Add(docObj);
                    }
                }

                //Replace pitures with the 'newPic'"
                foreach (DocumentObject pic in pictures)
                {
                    int index = para.ChildObjects.IndexOf(pic);
                    para.ChildObjects.Insert(index, newPic);
                    para.ChildObjects.Remove(pic);
                }
            }

            doc.SaveToFile("ReplaceWithImage.docx", FileFormat.Docx);

If this is not what you want, please provide your input file and desired output for further investigation. You could send them to us ([email protected]) via email. Thanks in advance.

Hello, thanks for the feedback, I had already tried this approach, but Header.Paragraph doesn't have access to the ChildObjects method and so I can't validate the components of this property like the image below.


Only this item is missing for us to check the possibility of acquiring the library, thank you for your feedback.
