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 `https://developer.android.com/reference/android/widget/ImageView.ScaleType.html` to animate contents smoothly.

## Public methods

### captureEndValues

```
public void captureEndValues(@NonNull TransitionValues transitionValues)
```

Captures the values in the end scene for the properties that this transition monitors. These values are then passed as the endValues structure in a later call to `https://developer.android.com/reference/androidx/transition/Transition#createAnimator(android.view.ViewGroup,androidx.transition.TransitionValues,androidx.transition.TransitionValues)`. The main concern for an implementation is what the properties are that the transition cares about and what the values are for all of those properties. The start and end values will be compared later during the `https://developer.android.com/reference/androidx/transition/Transition#createAnimator(android.view.ViewGroup,androidx.transition.TransitionValues,androidx.transition.TransitionValues)` method to determine what, if any, animations, should be run.

Subclasses must implement this method. The method should only be called by the transition system; it is not intended to be called from external classes.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/androidx/transition/TransitionValues transitionValues` | The holder for any values that the Transition wishes to store. Values are stored in the `values` field of this TransitionValues object and are keyed from a String value. For example, to store a view's rotation value, a transition might call `transitionValues.values.put("appname:transitionname:rotation", view.getRotation())`. The target view will already be stored in the transitionValues structure when this method is called. |

### captureStartValues

```
public void captureStartValues(@NonNull TransitionValues transitionValues)
```

Captures the values in the start scene for the properties that this transition monitors. These values are then passed as the startValues structure in a later call to `https://developer.android.com/reference/androidx/transition/Transition#createAnimator(android.view.ViewGroup,androidx.transition.TransitionValues,androidx.transition.TransitionValues)`. The main concern for an implementation is what the properties are that the transition cares about and what the values are for all of those properties. The start and end values will be compared later during the `https://developer.android.com/reference/androidx/transition/Transition#createAnimator(android.view.ViewGroup,androidx.transition.TransitionValues,androidx.transition.TransitionValues)` method to determine what, if any, animations, should be run.

Subclasses must implement this method. The method should only be called by the transition system; it is not intended to be called from external classes.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/androidx/transition/TransitionValues transitionValues` | The holder for any values that the Transition wishes to store. Values are stored in the `values` field of this TransitionValues object and are keyed from a String value. For example, to store a view's rotation value, a transition might call `transitionValues.values.put("appname:transitionname:rotation", view.getRotation())`. The target view will already be stored in the transitionValues structure when this method is called. |

### createAnimator

```
public @Nullable Animator createAnimator(
    @NonNull ViewGroup sceneRoot,
    @Nullable TransitionValues startValues,
    @Nullable TransitionValues endValues
)
```

Creates an Animator for ImageViews moving, changing dimensions, and/or changing `https://developer.android.com/reference/android/widget/ImageView.ScaleType.html`.

| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/android/view/ViewGroup.html sceneRoot` | The root of the transition hierarchy. |
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/Nullable.html https://developer.android.com/reference/androidx/transition/TransitionValues startValues` | The values for a specific target in the start scene. |
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/Nullable.html https://developer.android.com/reference/androidx/transition/TransitionValues endValues` | The values for the target in the end scene. |

| Returns |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/Nullable.html https://developer.android.com/reference/android/animation/Animator.html` | An Animator to move an ImageView or null if the View is not an ImageView, the Drawable changed, the View is not VISIBLE, or there was no change. |

### getTransitionProperties

```
public @NonNull String[] getTransitionProperties()
```

Returns the set of property names used stored in the `https://developer.android.com/reference/androidx/transition/TransitionValues` object passed into `https://developer.android.com/reference/androidx/transition/Transition#captureStartValues(androidx.transition.TransitionValues)` that this transition cares about for the purposes of canceling overlapping animations. When any transition is started on a given scene root, all transitions currently running on that same scene root are checked to see whether the properties on which they based their animations agree with the end values of the same properties in the new transition. If the end values are not equal, then the old animation is canceled since the new transition will start a new animation to these new values. If the values are equal, the old animation is allowed to continue and no new animation is started for that transition.

A transition does not need to override this method. However, not doing so will mean that the cancellation logic outlined in the previous paragraph will be skipped for that transition, possibly leading to artifacts as old transitions and new transitions on the same targets run in parallel, animating views toward potentially different end values.

| Returns |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html String[]` | An array of property names as described in the class documentation for `https://developer.android.com/reference/androidx/transition/TransitionValues`. The default implementation returns `null`. |

### isSeekingSupported

```
public boolean isSeekingSupported()
```

Returns `true` if the Transition can be used by `https://developer.android.com/reference/androidx/transition/TransitionManager#controlDelayedTransition(android.view.ViewGroup,androidx.transition.Transition)`. This means that any the state must be ready before any `https://developer.android.com/reference/android/animation/Animator.html` returned by `https://developer.android.com/reference/androidx/transition/Transition#createAnimator(android.view.ViewGroup,androidx.transition.TransitionValues,androidx.transition.TransitionValues)` has started and if the Animator has ended, it must be able to restore the state when starting in reverse. If a Transition must know when the entire transition has ended, a `https://developer.android.com/reference/androidx/transition/Transition.TransitionListener` can be added to `https://developer.android.com/reference/androidx/transition/Transition#getRootTransition()` and it can listen for `https://developer.android.com/reference/androidx/transition/Transition.TransitionListener#onTransitionEnd(androidx.transition.Transition)`.
