liip imagine filter on images stored in private file - symfony

Question

In my Symfony 6.2 i upload images to non public directory in my symfony /var/card-upload. In twig i display this image with
<img class="img-fluid img-thumbnail" src="{{ path('serve_private_image', {'id': card.id}) }}" alt="">
and for server image I have controller
<?php
namespace App\Controller;
use App\Entity\Card;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\BinaryFileResponse;
use Symfony\Component\Routing\Annotation\Route;
class ServePrivateImageController extends AbstractController
{
/**
* Returns a private image for card file for display.
*
* #Route("/serve-private-image/{id}", name="serve_private_image", methods="GET")
* #param Card $card
* #return BinaryFileResponse
*/
#[Route(path: '/serve-private-image/{id}', name: 'serve_private_image')]
public function privateImageServe(Card $card): BinaryFileResponse
{
return $this->fileServe($card->getImage());
}
/**
* Returns a private file for display.
*
* #param string $path
* #return BinaryFileResponse
*/
private function fileServe(string $path): BinaryFileResponse
{
$absolutePath = $this->getParameter('card_directory') . '/' . $path;
return new BinaryFileResponse($absolutePath);
}
}

<img class="img-fluid img-thumbnail" src="{{ path('serve_private_image', {'id': card.id}) | imagine_filter('my_thumb') }}" alt="">
