TCPDF Adobe не отображает Верхние и нижние колонтитулы

Question

Стипендиаты У меня есть выпускная печать Верхние и нижние колонтитулы с использованием TCPDF.

Классы, которые печатает PDF являются:

class MyPdf extends Pdf 
{ 
    private $eventid=null; 

    function __construct($event_id,$config=null) 
    { 
     parent::__construct($config); 

     $this->eventid=$event_id; 
    } 

    function Header() 
    { 
     if($this->eventid!==null) 
     { 
      $this->SetFont('dejavusans','',8); 
      $this->Cell(0,9,'eventid: '.$this->eventid); 
      $this->Ln(); 
     } 
    } 

    function Footer() 
    { 
     $this->setY(-20); 

     $x=$this->getX(); 
     $y=$this->getY(); 

     $this->Cell(0,9,'Powered By Ecampole.com INC ',0,0,'C'); 

     $this->setXY($x,$y); 

     $this->Cell(0,9,$this->PageNo(),0,0,'R'); 
     $this->Ln(1); 
    } 

} 

И библиотека PDF:

require_once('/usr/share/php/tcpdf/tcpdf_import.php'); 

define('FA_PATH',previous_dir(APPPATH).'assets/vendor/awesome/fonts/'); 

    class Pdf extends TCPDF 
    {

     private $faPath='fontawesomewebfont'; 

     /**

     */ 
     public function __construct($params)

И код, который рисует Pdf является:

    //define("_SYSTEM_TTFONTS",APPPATH.'/libraries/font/unifont'); 

    error_reporting(E_ERROR | E_PARSE); 
    define('TOP_MARGIN',30); 
    define('SIDE_MARGIN',5); 


    /**

    */ 
    class MyPdf extends Pdf 
    { 
     private $eventid=null; 

     function __construct($event_id,$config=null) 
     { 
      parent::__construct($config); 

      $this->eventid=$event_id; 
     } 

     function Header() 
     { 
      if($this->eventid!==null) 
      { 
       $this->SetFont('dejavusans','',8); 
       $this->Cell(0,9,'eventid: '.$this->eventid); 
       $this->Ln(); 
      } 
     } 

     function Footer() 
     { 
      $this->setY(-20); 

      $x=$this->getX(); 
      $y=$this->getY(); 

      $this->Cell(0,9,'Powered By Conferience',0,0,'C'); 

      $this->setXY($x,$y); 

      $this->Cell(0,9,$this->PageNo(),0,0,'R'); 
      $this->Ln(1); 
     } 

    } 


    $pdf new MyPdf($data['header']); 

    $pdf->SetAuthor($owner,true); 
    $pdf->SetCreator('Example.com INC',true); 
    $pdf->SetTitle($title,true); 
    $pdf->SetMargins(SIDE_MARGIN,TOP_MARGIN,SIDE_MARGIN); 

    $pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED); 
    $pdf->setFontSubsetting(true); 

    /* Add the first Page */ 
    $pdf->AddPage(); 

    /*####################### Size Metrics ###########################*/ 
    $remaining=$pdf->getHeight()-28-18-TOP_MARGIN; 
    $available_width=$pdf->getWidth()-SIDE_MARGIN-SIDE_MARGIN;

    $available_width_half=$available_width/2;

    $columns=($available_width)/12; 



    ?> 

Но для некоторых Причина evincew на linux показывает верхний и нижний колонтитулы, в то время как Firefox и Adobe 9.0 Professional на окнах их не показывают. Также Firefox не показывает нижний колонтитул.

У вас есть идеи, почему это происходит?

Answer 1

TCPDF имеет свою функцию для обработки верхних и нижних колонтитулов. Вы можете легко использовать TCPDF::setHeaderData() и TCPDF::setFooterData().
