Events

PSR-14 events available:

PosterImageCropVariantEvent In case the available crop variants for Image reference have been changed in your installation, this event can be used to change the used crop variant for the video poster image

PosterImageCropVariantEvent Listener

This example demonstrates how to register an event listener that modifies the crop variant of a poster image.

Event Listener Class

<?php
declare(strict_types=1);

namespace Vendor\MyExtension\EventListener;

use TRAW\VideoVtt\Events\PosterImageCropVariantEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener(identifier: 'my-extension/poster-crop-variant')]
class PosterImageCropVariantEventListener
{
    public function __invoke(PosterImageCropVariantEvent $event): void
    {
        $event->setCropVariant('desktop');
    }
}

Explanation

The listener reacts to the PosterImageCropVariantEvent and overrides the crop variant by calling:

$event->setCropVariant('desktop');

Registration

The event listener is registered automatically via the PHP attribute:

#[AsEventListener(identifier: 'lin-template/poster-crop-variant')]

No additional configuration in Services.yaml is required.

Result

Whenever the event is dispatched, the crop variant will be set to desktop.
