I am creating a material label that is required by my customer. I have successfully created the label format using PDF::API2 but now I need to add some barcodes and there I am stuck. Can/would someone offer some guidance?

    The documentation is a little sparse, but after a bit of digging through the sources, I've managed to come up with something that at least looks like a barcode... :)

    You probably want to play with the parameters.  Good luck!

    #!/usr/bin/perl use PDF::API2; my $pdf = PDF::API2->new(); my $page = $pdf->page(); my $gfx = $page->gfx(); my $barcode = $pdf->xo_ean13( # EAN-13 type -code => "0123456789012", # message -zone => 20, # size of bars -umzn => 25, # upper "mending zone" -lmzn => 15, # lower "mending zone" #-quzn => 0, # quiet zone #-ofwt => 0.5, # overflow width -font => $pdf->corefont('Helvetica'), -fnsz => 12, # font size #-ext => 1, # extended character set #-extn => '...', # barcode extension #-text => '', # alternative text ); $gfx->formimage($barcode, 250, 400, 1); # x y size (scaling) $pdf->saveas("barcode-test.pdf");

    (other available types are codabar, code128, 2of5int, 3of9)

    Check out GD::Barcode::Image you should be able to create the image then insert it into your PDF
