Problemas con fpdf en mc_table.php

[ejihe]

Estoy tratando de usar el ejemplo de de mc_table.php me genera bien las celdas el problema es que no me pinta el function Header() y function Footer() de la pagina al imprimir no me genera ningún Error pero no me imprime la cabecera ni pie de pagina estoy utilizando CODEINGNITER.

Código PHP:

<?php
require_once APPPATH."/libraries/fpdf/mc_table.php";
//$this->load->library('fpdf/fpdf');
//require('mc_table.php');
//$this->load->library('fpdf/fpdf'); 
//define(‘FPDF_FONTPATH’, ‘font/’);
//define('FPDF_FONTPATH','../font/'); 
class PDF extends FPDF 
{ 
//Page header 
function Header() 
{ 
//Logo 
// $this->Image('logo_pb.png',10,8,33); 
//Arial bold 15 
$this->SetTextColor(0,0,255); 
$this->SetFont('Arial','B',22); 
//Move to the right 
$this->Cell(80); 
//Title 
$this->Cell(30,10,'title',0,0,'C'); 
//Line break 
$this->Ln(10); 
//Arial italic 8 
$this->SetFont('Arial','I',8); 
//Page number 
$this->SetTextColor(0); 
$this->Cell(0,10,"Seite ".$this->PageNo().'/{nb}',0,0,'R'); 
//Line break 
$this->Ln(20); 
} 
 
//Page footer 
function Footer() 
{ 
//Position at 1.5 cm from bottom 
$this->SetY(-18); 
$this->Line(10,280,205,280); 
//Arial italic 8 
$this->SetFont('Arial','I',8); 
//Page number 
$this->Cell(40,10,"text",0,0); 
} 
} 
 
 
 
 
 
 
 
 
//Instanciation of inherited class 
$pdf=new PDF_MC_Table(); 
$pdf->Open(); 
$pdf->AliasNbPages(); 
$pdf->AddPage(); 
$pdf->SetFont('Arial','',12); 
 
////////////////////////// Tabelle ////////////////////////////////////////// 
 
$pdf->SetFont('Arial','',10); 
$pdf->SetWidths(array(25,100,15,20,20)); 
$i=0;
while ($i<=50) {
    $i++;
    # code...
 
$pdf->Row(array("sss","sasdddddddddddddddddddddddddddddddsssssssssssddddddddddddddddddddddddddddddddddddddddsddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd","ss","ss","ss"));
