namespace Rvdlee\ZfImageOptimiser\Factory\Adapter;

use Interop\Container\ContainerInterface;
use Rvdlee\ZfImageOptimiser\Adapter\Optipng;

class OptipngFactory extends AbstractImageOptimiserFactory
{
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
    {
        /** @var array $args */
        $args = parent::__invoke($container, $requestedName, $options);

        return new Optipng(...$args);

It seems like $args can also be of type Zend\Validator\ValidatorChain; however, parameter $binaryOptions of Rvdlee\ZfImageOptimiser\Adapter\Optipng::__construct() does only seem to accept array, maybe add an additional type check?

    }
