title: Receiving "file not found" Zend PDF
body: <p>The below code is a sample and it works (loads pdf from file, draws a single string, Success), however if I change the invoice.pdf (example pdf from a tutorial) to my pdf, buyersguide.pdf I receive an error on firefox, File not found.</p>
  
  <pre><code>    &lt;?php
     header("Content-Type: application/x-pdf");
     //header("Content-Disposition: attachment; filename=invoice-". date("Y-m-d-H-i") . ".pdf");
     header("Cache-Control: no-cache, must-revalidate");
  
     require_once 'zendframework/library/Zend/Loader/Autoloader.php';
     //Zend_Loader::registerAutoload();   
  
     $loader = Zend_Loader_Autoloader::getInstance();
  
     // load the invoice
  
     $invoice = Zend_Pdf::load("invoice.pdf");
     $page = $invoice-&gt;pages[0];
  
  
     $font = Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_TIMES_BOLD);
  
     $page-&gt;setFont($font, 12);
  
     // invoice information*/
     $page-&gt;drawText('success ', 420,642);
  
     // output the PDF
     echo $invoice-&gt;render();
  ?&gt;
  </code></pre>
  
  <p>Code with filename changed:</p>
  
  <pre><code>    &lt;?php
     header("Content-Type: application/x-pdf");
     //header("Content-Disposition: attachment; filename=invoice-". date("Y-m-d-H-i") . ".pdf");
     header("Cache-Control: no-cache, must-revalidate");
  
     require_once 'zendframework/library/Zend/Loader/Autoloader.php';
     //Zend_Loader::registerAutoload();   
  
     $loader = Zend_Loader_Autoloader::getInstance();
  
     // load the invoice
  
     $invoice = Zend_Pdf::load("buyersguide.pdf");
     $page = $invoice-&gt;pages[0];
  
  
     $font = Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_TIMES_BOLD);
  
     $page-&gt;setFont($font, 12);
  
     // invoice information*/
     $page-&gt;drawText('success ', 420,642);
