I need to get the existing margins(left, right, top, bottom) on a page of pdf file in perl, here is the code to get the dimension of padf page. 

use CAM::PDF;

my $pdf = CAM::PDF->new('test2.pdf');

my $num_page=$pdf->numPages();
print "Total Pages : $num_page\n";

my ($x,$y,$width,$height)=$pdf->getPageDimensions(2);
print "Dimension of PDF File : $width x $height  px \n";
