in reply to Add Border to a PDF file

Do you mean adding a border around each page?

The following uses PDF::API2 directly to draw a 1 pt border 10pt (~3.5mm) in from the edge of the page 

#!/usr/bin/perl
use warnings; use strict;

use PDF::API2;

my $pdf = PDF::API2->open('/tmp/test.pdf');

foreach my $pagenum (1 .. $pdf->pages) {

  my $page = $pdf->openpage($pagenum);
  #
  # Get the page size
  #
  my @mbox = $page->get_mediabox;

  my $gfx = $page->gfx;
  #
  # 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->savas('/tmp/test1.pdf');

    Thanks, your code is a really a good beginning. Problem here that the border overwrites the content of the PDF file. In that cause, I would rather draw the border outside the content, or shrink the page first and then draw the border.

      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');
