I had the same problem.  To get the barcodes I had to use a different
function entirely.
I've actually made a lot of changes to this script, but I will post the
relevant bit for your benefit.

my $zone = length($code) - 5;
      my $barcode = $pdf->xo_3of9(-font => $tr,	# The font object to use
      			    -code => $code, # Text to codify
      			    -ext  => 1,		# extended character set
      			    -extn => '012345',	# Barcode extension (if it is aplicable)
      			    -umzn => 9+$zone,	# Top limit of the finished bar
      			    -lmzn => 9+$zone,	# Bottom limit of the finished bar
      			    -zone => 3+$zone,	# Bars size
      			    -quzn => 0,		# Space destinated for legend
      			    -ofwt => 0.5,	# Bars width

      			    ); # umzn +, lmzn +, zone +7
# Assigns a barcode to $gfx
      my $scale = ($labelConfig{'labelWidth'}-2)/$barcode->width();
      $gfx->formimage($barcode, $x, $y, $scale);
      # Assigns the additional information to the barcode (Legend)
      if ($text_under_label) {
          my @lines = split("\n",$text_under_label);
          $title = $lines[0];
          $author = $lines[1];
      }
      while ($text->advancewidth($title) > ($labelConfig{'labelWidth'} - 2))
{
          chop $title;
      }
      while ($text->advancewidth($author) > ($labelConfig{'labelWidth'} -
2)) {
          chop $author;
      }
my ($x_adjust_1, $x_adjust_2, $y_adjust) = (0, 0, 0);
      if ($text->advancewidth($title) < ($labelConfig{'labelWidth'} - 5)) {
          $x_adjust_1 = (($labelConfig{'labelWidth'} - 2) -
$text->advancewidth($title)) / 2;
      }
      if ($text->advancewidth($author) < ($labelConfig{'labelWidth'} - 5)) {
          $x_adjust_2 = (($labelConfig{'labelWidth'} - 2) -
$text->advancewidth($author)) / 2;
      }
      $y_adjust = ($labelConfig{'labelHeigth'} - $barcode->height - 18) / 2;
      $y_adjust = 5 if ($y_adjust < 0);
      $y_adjust += $barcode->height;
$text->translate($x + $x_adjust_1, $y + $y_adjust + 9);
      $text->text($title);
      $text->translate($x + $x_adjust_2, $y + $y_adjust);
      $text->text($author);

Dear all,f - Numéro d'inventaire
Want to thank Henri-Damien LAURENT to fabulous help!
Now I am trying to generate barcodes.
First I wanna know if "Inventory code" asked  to generate the barcode 
is the same that we enter when adding an item (f - Numéro d'inventaire 
in additem.pl)? Because I give the same number (1000) and it says that 
there was any with that code (using Individual Codes in generator). If 
I select Continuous Range of Items from 0 to 1000 it proceeds...A bit 
odd :). Any ideas?
However it still was not ok. First I had to change some scripts 
becouse PDF::API2 has changed a bit and things are not anymore in the 
same place (e.g PDF::API::Utils is now PDF::API2::Basic::PDF::Utils). 
This I figured out myself. But now I got
Can't locate object method "barcode" via package "PDF::API2::Content" 
at /usr/local/koha/intranet/cgi-bin/barcodes/barcodesGenerator.pl line 
259
and this one I still couldn't solve. Anyone can help?

thax for aswering. Can you attach the full barcodeGenerator.pl? This 
piece of code should replace the code under continuous generation 'if' 
and the correspondant 'else'?
