ChangeImageTransform

open class ChangeImageTransform : Transition
kotlin.Any
   ↳ androidx.transition.Transition
   ↳ androidx.transition.ChangeImageTransform

This Transition captures an ImageView's matrix before and after the scene change and animates it during the transition.

In combination with ChangeBounds, ChangeImageTransform allows ImageViews that change size, shape, or android.widget.ImageView.ScaleType to animate contents smoothly.
