Symfony is adding to file size when downloading from controller - symfony

Question

I have uploaded an image with the VichUploaderBundle am returning an image file like so:
/**
* Show license image.
*
* #param Request $request
* #return Response
*/
public function showImageAction(Request $request,$id)
{
$em = $this->getDoctrine()->getManager();
$license = $em->getRepository('MyCarBundle:License')->findOneById($id);
$fileName = $license->getFrontName();
$user = $this->getUser();
$contents = '';
$filePath = __DIR__ . '/../../../../app/uploads/licenses/'. $user->getId().'/'.$fileName;
$response = new Response();
$disposition = $response->headers->makeDisposition(ResponseHeaderBag::DISPOSITION_INLINE, $fileName);
$response->headers->set('Content-Disposition', $disposition);
$response->headers->set('Content-Type', 'image/jpg');
$response->setContent(file_get_contents($filePath));
return $response;
}
and in html im trying to show the image, like so
<img class="img-fluid w-100 u-block-hover__main--zoom-v1" src="{{ path('license_show_image',{'id':license.id}) }}" alt="Image Description">
The image was uploaded succesfully. When I open the image in the uploaded folder, it is showing fine.
But the image is not showing in the browser. while directly accessing the url, the image is downloading but it is not able to open. It is giving me the following error:
The file “ODL_Eng_Full_Back-5.jpg” could not be opened.
Does anyone know whats going on?
UPDATE:
Symfony is adding ~700kb to the file size when downloading. after uploading it seems to have proper file size, but downloading adds file size. whats going on here?
UPDATE 2:
these are the headers:

Answer 1

You can use BinaryFileResponse (doc
) like:
$response = new BinaryFileResponse($filepath);
$response->headers->set('Content-disposition', sprintf('filename=%s', basename($filepath)));
return $response;

Answer 2

EDIT : HTTP Response seems to be correct.
Since you're using VichUploaderBundle, why not just use its helpers ?
<img src="{{ vich_uploader_asset(license, 'frontName') }}" alt="{{ license.frontName }}">
