```kotlin
@JvmDefaultWithCompatibility
interface TransformableState
```


State of `transformable`. Allows for a granular control of how different gesture transformations
are consumed by the user as well as to write custom transformation methods using `transform`
suspend function.


## Properties

<div class='sourceset sourceset-common'>Common</div>


```kotlin
val isTransformInProgress: Boolean
```


Whether this `TransformableState` is currently transforming by gesture or programmatically or
not.



## Functions

```kotlin
suspend fun transform(
        transformPriority: MutatePriority = MutatePriority.Default,
        block: suspend TransformScope.() -> Unit,
    )
```


Call this function to take control of transformations and gain the ability to send transform
events via `TransformScope.transformBy`. All actions that change zoom, pan or rotation values
must be performed within a `transform` block (even if they don't call any other methods on
this object) in order to guarantee that mutual exclusion is enforced.

If `transform` is called from elsewhere with the `transformPriority` higher or equal to
ongoing transform, ongoing transform will be canceled.
