Change "title" of QR

[xiaoCreagia]

When using QR the result image filename is the first parameter, in this case the 'url'. How to sepparate the filename to the url which should redirect QR? It's possible?

$qr = new DNS2D();
$qr->setStorPath(base_path('public/storage/qrcodes/'));
$qr->getBarcodePNGPath($url, 'QRCODE', 50, 50);
