C# Question

How do I insert a background image on all pages of a pdf-document?

I need sample code in C# to insert the background image on all pages of the finished pdf-document. I'm using iTextSharp library.

You can try this;

void makePDF()
    Response.ContentType = "application/pdf";

    Response.AddHeader("content-disposition", "attachment;filename=test.pdf");


    string imageFilePath = Server.MapPath(".") + "/images/test.jpg";

    iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageFilePath);

    // Page site and margin left, right, top, bottom is defined
     Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);

    //Resize image depend upon your need
    //For give the size to image
     jpg.ScaleToFit(3000, 770);

    //If you want to choose image as background then,

    jpg.Alignment = iTextSharp.text.Image.UNDERLYING;

    //If you want to give absolute/specified fix position to image.
    jpg.SetAbsolutePosition(7, 69);

    PdfWriter.GetInstance(pdfDoc, Response.OutputStream);



    Paragraph paragraph = new Paragraph("this is the testing text for demonstrate the image is in background \n\n\n this is the testing text for demonstrate the image is in background");
