//Page header
public function Header() {
$auto_page_break = $this->AutoPageBreak;
$this->SetAutoPageBreak(false, 0);
$img_file = 'img/pdf_fondo.jpg';
$this->Image($img_file, $x=0, $y=0, $w=210, $h=297, $type='', $link='', $align='', $resize=false, $dpi=300, $palign='', $ismask=false, $imgmask=false, $border=0);
