how to add an image to my header in iText generated PDF?

Question

I\'m using iText to generate a PDF. I created a custom PdfPageEventHelper to add a header (and footer) to each page.

My problem is I don\'t know how to add the imag

Answer 1

I've set abolute positions and alignment to the image (in this case I placed my image in the header)

    try {
        Image img = Image.getInstance("url/logo.png");
        img.scaleToFit(100,100);  
        img.setAbsolutePosition((rect.getLeft() + rect.getRight()) / 2 - 45, rect.getTop() - 50);
        img.setAlignment(Element.ALIGN_CENTER);          
        writer.getDirectContent().addImage(img);
      } catch (Exception x) {
        x.printStackTrace();
      }

I've also adjusted the the document margins in order to have delimited space in the header and footer of the document.

document.setMargins(20, 20, 100, 100);
