Here's a second cut. This preserves the page size
and shrinks the graphics by 10%:
#!/usr/bin/perl
use warnings; use strict;
use PDF::API2;
my $pdf_in = PDF::API2->open('/tmp/test.pdf');
my $pdf_out = PDF::API2->new;
foreach my $pagenum (1 .. $pdf_in->pages) {
my $page_in = $pdf_in->openpage($pagenum);
#
# create new page
#
my $page_out = $pdf_out->page(0);
#
# Get the page size
#
my @mbox = $page_in->get_mediabox;
#
# Inherit mediabox
$page_out->mediabox(@mbox);
#
#
# copy page as a form. reduce slightly.
#
my $xo = $pdf_out->importPageIntoForm($pdf_in, $pagenum);
my $gfx = $page_out->gfx;
$gfx->formimage($xo,
my $_x = 20, my $_y = 20,
my $_scale = .9);
#
# Draw a box 10pt in from the edges of the page
#
$gfx->linewidth(1);
$gfx->strokecolor('#000000');
$gfx->rect($mbox[0]+10, $mbox[1]+10, $mbox[2]-20, $mbox[3]-20);
$gfx->stroke;
}
$pdf_out->saveas('/tmp/test2.pdf');
