It is automatically called by {@link addPage()} and {@link close()} and
should not be called directly by the application. The implementation in
Horde_Pdf_Writer is empty, so you have to subclass it and override the method
if you want a specific processing.
Example:
class My_Pdf extends Horde_Pdf_Writer {
function footer()
{
Go to 1.5 cm from bottom
$this->setY(-15);
Select Arial italic 8
$this->setFont('Arial', 'I', 8);
Print centered page number
$this->cell(0, 10, 'Page ' . $this->getPageNo(), 0, 0, 'C');
}
}
