the out of the box functionality "Smart Cropping" is only available in the ContentCreator.
But there is a project solution called "Smart Resolutions" that is also working in the site architect. We once introduced that module by one of our customers.
Thank you so much for your answer. It was very helpful. Could you please tell me a lillte bit more about this "Smart Resolutions". We also need it for a cosutumer.
the best way would be that you contact your sales and / or partner contact at e-Spirit. Because the module is developed by a e-Spirit partner and must be purchased. (Send them greetings from me 😉)
The module itself provides a special meta data template for images where you can use the hotspot input component to select a focus point on images. The module then creates croppings for all resolutions. If you do not select a focus point the module is taking a "best guess" and crops all images with a focus point in the middle of the images.
Also a batch cropping for all images in a folder or just for a single resolution group is possible. Resolutions are grouped automatically by their image ratios so that you can reuse a focus point for e.g. all 16:9 resolutions.
