Images, Headers and Footers

Adding an Image

import com.itextpdf.layout.element.Image;
import com.itextpdf.io.image.ImageDataFactory;

Image logo = new Image(ImageDataFactory.create("logo.png"));
logo.setWidth(120);
document.add(logo);

Page Headers and Footers

int pages = pdf.getNumberOfPages();
for (int i = 1; i <= pages; i++) {
    Document d = new Document(pdf);
    d.showTextAligned(new Paragraph("Page " + i + " of " + pages),
        550, 20, i, TextAlignment.RIGHT, VerticalAlignment.BOTTOM, 0);
}

Add footers after the main content is written, once the page count is known.
