I am able to change fonts in TCPDF such as using:
$pdf->SetFont('aefurat', '', 12);
The default line for footer is:
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
So I tried using something like
$pdf->setFooterFont(Array('dejavusans', '', PDF_FONT_SIZE_DATA));
but no good as the footer fonts simply does not change nor if I change the size too. Am I missing something?
