Here is the code to change the title for a PDF. This should get you pointed in the right direction: 
#!/usr/bin/perl
use PDF::API2;
$pdf = PDF::API2->open('test.pdf');
#%info = $pdf->info;
$font = $pdf->corefont("Times-Roman");
$info{Title} = $font->text( "New Title");
$pdf->info (%info);
$pdf->update;
$pdf->saveas("newfile.pdf");

[download]
PDF::API2 is on CPAN

HTH, --traveler

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
