Where are image resizing filters defined?

In Sylius 2.x, image resizing filters are configured under liip_imagine in your config/packages/liip_imagine.yaml file. By default, Sylius provides a comprehensive set of filters for both the Admin and Shop interfaces.

Here are the default filters:

Filter Name	Size (px)	Description
sylius_admin_product_original	Original	Full-size admin product image
sylius_admin_avatar	200x200	Admin avatar thumbnail
sylius_admin_product_large_thumbnail	600×800	Large product image in admin
sylius_admin_product_thumbnail	200×200	Generic admin thumbnail
sylius_shop_product_original	Original	Full-size shop product image
sylius_shop_product_small_thumbnail	300×400	Small product image in shop
sylius_shop_product_thumbnail	600×800	Main product thumbnail in shop
sylius_shop_product_large_thumbnail	1200×1600	Large product image in shop
sylius_small	120×90	Generic small image size

How to Apply Image Filters in Twig

Use the imagine_filter Twig filter to apply it to an image path.

Example

<img src="{{ object.path|imagine_filter('sylius_small') }}" alt="Thumbnail" />

Sylius stores image paths (e.g. for products or avatars) in the path field of image entities. The default public path for media is /media/image.

How to Edit existing filters

Let's assume you want to change the size of images under sylius_shop_product_large_thumbnail filter to 100 x 200:

# config/packages/liip_imagine.yaml
liip_imagine:
    filter_sets:
        sylius_shop_product_large_thumbnail:
            format: webp
            quality: 80
            filters:
                thumbnail: { size: [ 100, 200 ], mode: inset }

Remember to clear cache after the changes!

php bin/console liip:imagine:cache:remove

How to Add Custom Image Resizing Filters

# config/packages/liip_imagine.yaml
liip_imagine:
    filter_sets:
        advert_banner:
            filters:
                thumbnail: { size: [800, 200], mode: inset }
