function hook_image_style_flush

Respond to image style flushing.

This hook enables modules to take effect when a style is being flushed (all images are being deleted from the server and regenerated). Any module-specific caches that contain information related to the style should be cleared using this hook. This hook is called whenever a style is updated, deleted, or any effect associated with the style is update or deleted.

Parameters

\Drupal\image\ImageStyleInterface $style: The image style object that is being flushed.
