Renderers have some common options. These options can be set in three ways:
* As an array or a Traversable object passed to the constructor.
* As an array passed to the setOptions() method.
* As discrete values passed to individual setters.
Different ways to parameterize a renderer object
use Zend\Barcode\Renderer;
$options = array('topOffset' => 10);
// Case 1
$renderer = new Renderer\Pdf($options);
// Case 2
$renderer = new Renderer\Pdf();
$renderer->setOptions($options);
// Case 3
$renderer = new Renderer\Pdf();
$renderer->setTopOffset(10);
