LiipImagineBundle does not apply filter to SVG file. How to fix it?

IMPORTANT

Maybe it is not the best solution, but this workaround works for me. If you have a better solution, please let me know.

Introduction

LiipImagineBundle (applying filter to a SVG file) still have some issues. If you try to apply a filter to an SVG file, you will get the following error:

Unable to create image for path "X.svg" and filter "XXX".
Message was "An image could not be created from the given input".

Solution:

Quick solution: return the original svg file if the requested file is an svg file.

Step 1:

Create a new controller that extends the Liip\ImagineBundle\Controller\ImagineController and override the filterAction method.

src/Controller/ImagineController.php

<?php

namespace App\Controller;

use Liip\ImagineBundle\Config\Controller\ControllerConfig;
use Liip\ImagineBundle\Imagine\Cache\SignerInterface;
use Liip\ImagineBundle\Imagine\Data\DataManager;
use Liip\ImagineBundle\Service\FilterService;
use Symfony\Component\DependencyInjection\Attribute\Autowire;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;

class ImagineController extends \Liip\ImagineBundle\Controller\ImagineController
{
    public function __construct(
        #[Autowire(service: 'liip_imagine.service.filter')]
        FilterService $filterService,
        #[Autowire(service: 'liip_imagine.data.manager')]
        DataManager $dataManager,
        #[Autowire(service: 'liip_imagine.cache.signer')]
        SignerInterface $signer,
        #[Autowire(service: 'liip_imagine.controller.config')]
        ControllerConfig $controllerConfig = null
    ) {
        parent::__construct($filterService, $dataManager, $signer, $controllerConfig);
    }

    /**
     * @param Request $request
     * @param string $path
     * @param string $filter
     * @Route("/imagine")
     */
    public function filterAction(Request $request, $path, $filter): RedirectResponse
    {
        if (pathinfo($path, PATHINFO_EXTENSION) === 'svg') {
            return new RedirectResponse("/$path");
        }

        return parent::filterAction($request, $path, $filter);
    }
}

Step 2:

Add controller configuration to the liip_imagine.yaml file.

config/packages/liip_imagine.yaml

liip_imagine:
+    controller:
+        filter_action: \App\Controller\ImagineController::filterAction

Step 3:

Waiting for normal support of SVG files in LiipImagineBundle.

That`s it.
