How can I add an image to all pages of my PDF?

I have been trying to add an image to all pages using iTextSharp. The image needs to be OVER all content of every page.

I have used the following code below all the otherdoc.add()


Document doc = new Document(iTextSharp.text.PageSize.A4, 10, 10, 30, 1);
PdfWriter writer = PdfWriter.GetInstance(doc,
    new FileStream(Server.MapPath("~/pdf/" + fname), FileMode.Create));
Image image = Image.GetInstance(Server.MapPath("~/images/draft.png"));
image.SetAbsolutePosition(12, 300);
writer.DirectContent.AddImage(image, false);
The above code only inserts an image in the last page. Is there any way to insert the image in the same way in all pages?

It's normal that the image is only added once; after all: you're adding it only once.

You should create a document in 5 steps and add an event in step 2:

// step 1
Document document = new Document();
// step 2
PdfWriter writer = PdfWriter.GetInstance(document, stream);
MyEvent event = new MyEvent();
writer.PageEvent = event;
// step 3
// step 4
// Add whatever content you want to add
// step 5

You have to write the MyEvent class yourself:

protected class MyEvent : PdfPageEventHelper {

    Image image;

    public override void OnOpenDocument(PdfWriter writer, Document document) {
        image = Image.GetInstance(Server.MapPath("~/images/draft.png"));
        image.SetAbsolutePosition(12, 300);

    public override void OnEndPage(PdfWriter writer, Document document) {

The OnEndPage() in class MyEvent will be triggered every time the PdfWriter has finished a page. Hence the image will be added on every page.

Caveat: it is important to create the image object outside the OnEndPage() method, otherwise the image bytes risk being added as many times as there are pages in your PDF (leading to a bloated PDF).
