Overview

A region of interest defines a rectangular portion of a photo corresponding to a face. Use a region of interest to determine where to focus, zoom, or crop your image in your project extension; for example, you can customize your slideshow’s transitions based on each photo’s highest-quality region of interest, as shown in Creating a Slideshow Project Extension for Photos.
