what should do,so able copy contents of pdf created. achievable? please guide me same. thanks! code:

 require_once('tcpdf_include.php');  $pdf = new tcpdf(pdf_page_orientation, pdf_unit, pdf_page_format, true, 'utf-8', false);   $pdf->setprotection($permissions = array('print', 'modify', 'copy', 'annot-forms', 'fill-forms', 'extract', 'assemble', 'print-high'), '', null, 0, null);   $pdf->setcreator(pdf_creator);    $pdf->setheaderdata(pdf_header_logo, pdf_header_logo_width, 'license export details');   // set header , footer fonts  $pdf->setheaderfont(array('helvetica', '', pdf_font_size_main));  $pdf->setfooterfont(array('helvetica', '', pdf_font_size_data));   // set default monospaced font  $pdf->setdefaultmonospacedfont(pdf_font_monospaced);   // set margins  $pdf->setmargins(pdf_margin_left, pdf_margin_top, pdf_margin_right);  $pdf->setheadermargin(pdf_margin_header);  $pdf->setfootermargin(pdf_margin_footer);   // set auto page breaks   $pdf->setautopagebreak(true, pdf_margin_bottom);   // set image scale factor   $pdf->setimagescale(pdf_image_scale_ratio);   // set language-dependent strings (optional)   if (@file_exists(dirname(__file__).'/lang/eng.php')) { require_once(dirname(__file__).'/lang/eng.php'); $pdf->setlanguagearray($l);         }    $pdf->setfont('times', '', 16);   // add page   $pdf->addpage();   //write html   $html='================= data==============';   //convert html pdf document  $pdf->writehtml($html, true, false, true, false, '');  //close , output pdf document   $pdf->output('export_details.pdf', 'd'); 

i think should delete these 2 lines

$pdf->setprotection($permissions = array('print', 'modify', 'copy', 'annot-forms', 'fill-forms', 'extract', 'assemble', 'print-high'), '', null, 0, null);  $pdf->setcreator(pdf_creator);
