FormatExtensionResolver

Configuration

To use this cache resolver, you must first define the cache resolver it will decorate. In this example, we will use the Web Path Resolver.

Next, we need to define a service for this cache resolver and inject the web path cache resolver service to decorate.

# app/config/services.yml

services:
    acme.imagine.cache.format_extension:
        class: Liip\ImagineBundle\Imagine\Cache\Resolver\FormatExtensionResolver
        arguments:
            - "@acme.imagine.cache.resolver.web_path"
            - "@liip_imagine.filter.configuration"
        tags:
            - { name: "liip_imagine.cache.resolver", resolver: "format_extension" }

With this configuration, the format extension resolver will rewrite the extension to match the filter format. For example, you have the source image image.png and you apply filter with format jpg you will get jpeg-image image.jpg.

Usage
