position (10,16) from it, pastes it into target.png at position (32,64) and
saves the result as target-new.png. It does not choke if source.png is
truncated.

use Gtk2;
my $load = Gtk2::Gdk::PixbufLoader->new;
my $input = do {
  open my $if, "<", "source.png" or die "source.png: $!\n";
  local $/;
  <$if>;
};
$load->write($input);
my $src = $load->get_pixbuf;
my $dst = Gtk2::Gdk::Pixbuf->new_from_file("target.png");
$src->copy_area(10, 16, 420, 160, $dst, 32, 64);
$dst->save("target-new.png", "png", compression => 9);
$load->close;
