Test::More::is_deeply is not ignoring an argument - that argument is never reaching it. That's because, in list (array) context (i.e., "wantarray" returns true), it is returning an empty list.

Try:

is_deeply(scalar $pdf->adjust_to_bounding_box($main_image),  
          undef, 
          "adjust_to_bounding_box returns on no second param" 
         ); # test

And compare with: 
my @got = $pdf->adjust_to_bounding_box($main);
# @got should be an empty list.

Hope that helps.
