PDF :: API2如何返回原始PDF

Question

I have created a PDF using PDF::API2. How can I return the raw PDF?

Example:

my $pdf = PDF::API2->new();

$pdf = PDF::API2->open('./useful_scripts/invoice.pdf');
my $page = $pdf->openpage(1);

my $content = $page->text();
my $font = $pdf->corefont('Helvetica-Bold');
$content->fillcolor('black');
$content->font($font, 11);

$content->translate(170, 785);
$content->text($invoice->ott_invoice_number);

#Finally return raw $pdf

I am aware of the $pdf->saveas() method, but I don't actually want to save my PDF to a file.

Answer 1

IRC #perl-help answer:

my $raw_pdf = $pdf->stringify();

does the job.
