Provides basic API for image cropping. This module won't do much by itself. Users should pick one of UI modules that utilize this API.
- Latest dev release of Drupal 8.x.
There is one configuration which can be used to prevent crop from flushing image derivatives upon save. See Decoupled file storage for details.
Initial discussion can be found on manual crop issue queue.
By default whenever a crop entity is saved the image_styles associated with the file entity are flushed so that Drupal will regenerate them using the updated crop information the next time they are requested. If you are manually generating your image derivatives instead of waiting for them to be generated on the fly, because you are using a cloud storage service (like S3) you can use the following code to tell not flush image_style automatically.
By default the flush_derivative_images configuration is set to true. To
prevent image derivatives from being flushed you can use the following code:
$config['crop.settings']['flush_derivative_images'] = false;
