- 8 core/modules/image/src/PathProcessor/PathProcessorImageStyles.php \Drupal\image\PathProcessor\PathProcessorImageStyles
Defines a path processor to rewrite image styles URLs.
As the route system does not allow arbitrary amount of parameters convert the file path to a query parameter on the request.
This processor handles two different cases:
- public image styles: In order to allow the webserver to serve these files directly, the route is registered under the same path as the image style so it took over the first generation. Therefore the path processor converts the file path to a query parameter.
- private image styles: In contrast to public image styles, private derivatives are already using system/files/styles. Similar to public image styles, it also converts the file path to a query parameter.
