How it's work

Saving contextual crop data

- On referenced field
For media referenced fields, the Media Contextual Cropping Reference module will use media_library_media_modify (waiting core feature resolution) in order to set and save contextual Crop Data

- On embed Media
For embed Media, the the media_contextual_crop_field_embed module provide a CKeditor 5 plugin in order to invoke a modal for setting crop Data.
These data are saved in the drupal-media html node inside the wysiwyg.

Render multiple derivativ from the same media/image with the same style (but different crop)

This is bigger issue with this kind of functionality. The Drupal Core ImageStyle processing CAN NOT (By Design) produce more than one derivativ for one couple Image/Style.
The CROP API, just add the capability to "choose" the part of the image.

In order to avoid this problem, MediaContextualCrop modules (2.x) branch are based on a specific image_formater (replacing the core one) to generate a contextualized URL.

"Et voila"

1.x to 2.x Update process

The central point of this migration is the use of a specific "Contextual Crop Image" format on the media image field.
This formatter must be present on the image field to use the contextual crop.
A Drush command ( drush media_contextual_crop:migrateToImageFormater ) can do the configuration changes automatically (only on media entites and if the chosen image style uses a crop).
