Dear Monks,

I am using API2 package (to generate PDF report) for the first time and trying to test it via simple Hello World Code. The moment I try to write something to the pdf file, I get errors from Content.pm. If i simply create new file and save it, it does create blank pdf file. I am working in Linux environment.If there is another way to generate pdf report, please let me know.

This is my code: 
use PDF::API2;
use PDF::API2::Util;
my $pdf = PDF::API2->new();

my $font = $pdf->corefont('Times-Roman');

my $page = $pdf->page;

$page->mediabox(595,842);
my $gfx=$page->gfx;

$gfx->textlabel(50,780,$font,20,"Hello World! (3)");

#my $headline_text = $page->text;

#$headline_text->text("Hello World");


$pdf->saveas("/tmp/HelloWorld.pdf");

$pdf->end();

and got this error:
