As I'd said, it's a direct copy/paste from the linked tutorial. I'll
reproduce it here anyway:
/**
* @see
com.lowagie.text.pdf.PdfPageEventHelper#onEndPage(com.lowagie.text.pdf.PdfWriter,
com.lowagie.text.Document)
*/
public void onEndPage(PdfWriter writer, Document document) {
try {
Rectangle page = document.getPageSize();
PdfPTable head = new PdfPTable(3);
for (int k = 1; k <= 6; ++k)
head.addCell("head " + k);
head.setTotalWidth(page.getWidth() - document.leftMargin() -
document.rightMargin());
head.writeSelectedRows(0, -1, document.leftMargin(),
page.getHeight() - document.topMargin() + head.getTotalHeight(),
writer.getDirectContent());
PdfPTable foot = new PdfPTable(3);
for (int k = 1; k <= 6; ++k)
foot.addCell("foot " + k);
foot.setTotalWidth(page.getWidth() - document.leftMargin() -
document.rightMargin());
foot.writeSelectedRows(0, -1, document.leftMargin(),
document.bottomMargin(),
writer.getDirectContent());
}
catch (Exception e) {
throw new ExceptionConverter(e);
}
}
