namespace App\Presenters;

use Holabs\DomPDF\Factory;
use Nette\Application\UI\Presenter;


class PDFPresenter extends Presenter {

	/** @var Factory */
	public $dompdfFactory;

	public function actionDefault() {

		$document = $this->dompdfFactory->create();
		
		$this->sendResponse($document);
	}

}
