How do I insert an image into the first footer?

Question

I create a footer, insert the text without any problems.

        static void Main(string[] args)
    {
        CreateFooter(@"D:\1.docx");

     }

    static void CreateFooter(String documentPath)
    {
      
    using (WordprocessingDocument document = WordprocessingDocument.Open(documentPath, true))
        {
       
            MainDocumentPart mainDocumentPart = document.MainDocumentPart;
            mainDocumentPart.DeleteParts(mainDocumentPart.FooterParts);
     
            FooterPart footerPart = mainDocumentPart.AddNewPart<FooterPart>();

            string footerPartId = mainDocumentPart.GetIdOfPart(footerPart);

            GenerateFooter(footerPart);

            var sections = mainDocumentPart.Document.Body.Elements<SectionProperties>().FirstOrDefault();

                sections.RemoveAllChildren<FooterReference>();
                sections.PrependChild<FooterReference>(new FooterReference() { Id = footerPartId });

        }    
    }




    static void GenerateFooter(FooterPart part)
    {
        Footer footer1 = new Footer() { MCAttributes = new MarkupCompatibilityAttributes() { Ignorable = "w14 wp14" } };
        footer1.AddNamespaceDeclaration("wpc", "http://schemas.microsoft.com/office/word/2010/wordprocessingCanvas");

        footer1.AddNamespaceDeclaration("wps", "http://schemas.microsoft.com/office/word/2010/wordprocessingShape");

        Paragraph paragraph1 = new Paragraph() { RsidParagraphAddition = "00164C17", RsidRunAdditionDefault = "00164C17" };

        ParagraphProperties paragraphProperties1 = new ParagraphProperties();
        ParagraphStyleId paragraphStyleId1 = new ParagraphStyleId() { Val = "Footers" };
        using (FileStream stream = File.OpenRead(@"C:\Users\Амир\Downloads\Подпись.png"))
        {
            var img = Bitmap.FromStream(stream);

            paragraphProperties1.Append(paragraphStyleId1);

            Run run1 = new Run();
            Text text1 = new Text();
            text1.Text = "Footessr";

            run1.Append(text1);

            paragraph1.Append(paragraphProperties1);
            paragraph1.Append(run1);

            footer1.Append(paragraph1);

            part.Footer = footer1;
        }
    }

But there are a few problems, But there are a few problems that I can't solve.: 1 The problem is that I do not know how to insert an image. 2 How do I make sure that the footer is added only to 1 page? 3.How do I make sure that the footer is added to the bottom right

Answer 1

2 How do I make sure that the footer is added only to 1 page?

You can add footer reference type as HeaderFooterValues.First and add TitlePage property to section properties.

foreach (var section in sections)
 {
     // Delete existing references to  footers                   
     section.RemoveAllChildren<FooterReference>();
     section.PrependChild<TitlePage>(new TitlePage());
     // Create the new  footer reference node
     section.PrependChild<FooterReference>(new FooterReference() { Id = footerPartId, Type = HeaderFooterValues.First });
 }

3.How do I make sure that the footer is added to the bottom right

You can set Justification Class:This element specifies the paragraph alignment which shall be applied to text in this paragraph.

   Justification Right = new Justification() { Val = JustificationValues.Right };      
   paragraphProperties1.Append(Right);

1 The problem is that I do not know how to insert an image.

There is a lot of code for inserting an image. Please refer to the following code for details. (The paths of documents and images need to be changed)

static void Main(string[] args)
{
    CreateFooter(@"C:\1.docx");

}

static void CreateFooter(String documentPath)
{

    // Replace header in target document with header of source document.
    using (WordprocessingDocument document = WordprocessingDocument.Open(documentPath, true))
    {
        string imagePath = @"C:\Capture.PNG";
        setHeaderPicture(imagePath);
        // Get the main document part
        MainDocumentPart mainDocumentPart = document.MainDocumentPart;

        // Delete the existing footer parts             
        mainDocumentPart.DeleteParts(mainDocumentPart.FooterParts);
        // Create a new header and footer part

        FooterPart footerPart = mainDocumentPart.AddNewPart<FooterPart>();

        // Get Id of thefooter parts

        string footerPartId = mainDocumentPart.GetIdOfPart(footerPart);



        GenerateFooterPartContent(footerPart);

        ImagePart image = footerPart.AddNewPart<ImagePart>("image/PNG", "rId999");
        GenerateImagePart1Content(image);
        // Get SectionProperties and Replace FooterRefernce with new Id
        IEnumerable<DocumentFormat.OpenXml.Wordprocessing.SectionProperties> sections = mainDocumentPart.Document.Body.Elements<DocumentFormat.OpenXml.Wordprocessing.SectionProperties>();

        foreach (var section in sections)
        {
            // Delete existing references to  footers                   
            section.RemoveAllChildren<FooterReference>();
            section.PrependChild<TitlePage>(new TitlePage());
            // Create the new  footer reference node

            section.PrependChild<FooterReference>(new FooterReference() { Id = footerPartId, Type = HeaderFooterValues.First });
        }
    }
}
