LiipImagineBundle

Tightly integrates with Symfony's configuration system and templating engines like Twig, as shown by YML/XML config examples and the `imagine_filter` Twig filter for easy use in templates.

Enables complex image transformations through declarative filter sets with multiple filters and post-processors, demonstrated in the thumbnail creation example combining thumbnail and background filters.

Automatically caches processed images to boost performance on subsequent requests, reducing server load, as highlighted in the usage primer where images are cached after first access.

Supports custom filters and post-processors, allowing developers to extend functionality beyond built-in options like JPEG Optim or thumbnail filters, as noted in the documentation links.
