How to identify end of page is reached in pdf file using itextsharp

Question

Hi I am using itextsharp to generate a pdf file.I am placing a backgound image on it and want that image on all the pages .But when the first page is completed the text move to next page automatically so the image is not appearing on the new page.

Is there a way to identify the end of page so that we can add a new page and then set the image first so will appear in background and then can add the remaining text.

All is i want a image in background on all the pages of pdf file.

Just check PdfWriter.PageNumber property like this:

        using (FileStream fs = File.Create("test.pdf"))
        {
            Document document = new Document(PageSize.A4, 72, 72, 72, 72);
            PdfWriter writer = PdfWriter.GetInstance(document, fs);

            document.Open();
            int pageNumber = -1;

            for (int i = 0; i < 20; i++)
            {
                if (pageNumber != writer.PageNumber)
                {
                    // Add image
                    pageNumber = writer.PageNumber;
                }

                // Add something else
            }

            document.Close();
        }
