zoomBy
```kotlin
suspend fun TransformableState.zoomBy(zoomFactor: Float) =
zoomBy(zoomFactor = zoomFactor, centroid = Offset.Unspecified)
```
Zoom without animation by a ratio of `zoomFactor` over the current size and suspend until it's
set.
#### Parameters
| | |
| --- | --- |
| zoomFactor | ratio over the current size by which to zoom |
zoomBy
Common
```kotlin
suspend fun TransformableState.zoomBy(zoomFactor: Float, centroid: Offset = Offset.Unspecified) =
transform {
transformByWithCentroid(
centroid = centroid,
zoomChange = zoomFactor,
panChange = Offset.Zero,
rotationChange = 0f,
)
}
```
Zoom without animation by a ratio of `zoomFactor` over the current size and suspend until it's
set.
#### Parameters
| | |
| --- | --- |
| zoomFactor | ratio over the current size by which to zoom |
| centroid | the [Offset](/jetpack-compose/androidx.compose.ui/ui-geometry/functions/Offset) around which the zoom should occur, if any. The default value is [Offset.Unspecified], which leaves the behavior up to the implementation of the [TransformableState](/jetpack-compose/androidx.compose.foundation/foundation/functions/TransformableState). |
