of course the testfile.pdf  is an existing .pdf file, that's in the same directory as the .php file itself.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

sorry, the correct link must by :

We still need a short but complete reproduce case.

// this is the code that produces the error.

<?php
     // this is the file with most of the obsolete source stripped away
     $p = new PDFlib();
     
     /* open new pdf file; insert a file name to create the PDF on the disk */
     $p->begin_document("","")
     $p->set_info("Creator", "hello.php");
     $p->set_info("Author", "Rainer Schaaf");
     $p->set_info("Title", "Hello World (PHP)!");
     /* for testing purposes only */
     $filename = "ronnie.pdf";
     
     $p->open_pdi($filename, "",0);
     
     $p->setfont($font, 12.0);
     $p->set_text_pos(50,700);
     $p->show("Hello world!");
     $p->continue_text("  (says PHP)  ");
     $p->end_page_ext("");
     $p->end_document("");
     
     $buf = $p->get_buffer();
     $len = strlen($buf);
     
     header("Content-type: application/pdf");
     header("Content-length: $len");
     header("Content-Disposition: inline; filename=hello.pdf");
          
     print $buf;
?>

Excuse me for not looking far enough. I just found that it wasn't realy a bug but a licencing problem. I found a class called acrostix.php that solves the problem for me.
