Aren't you getting any warnings for that? I'm surprised Image::Magick doesn't complain about the invalid input.

The posted code has a bare string eval without any error checks ($@), so most errors will be silent. Also, Image::Magick requires a lot of manual error checks because it does not use perl's exception mechanism (i.e. die), but instead requires checking return values (as in C). This is documented in http://www.imagemagick.org/script/perl-magick.php#exceptions. The posted code lacks those checks, too.
