After some googling I found https://github.com/android/camera-samples/blob/master/CameraXBasic/app/src/main/java/com/android/example/cameraxbasic/utils/AutoFitPreviewBuilder.kt which does what I want. Would it be possible to fold this into the main library or at least make it configurable without the need for that class?

Hi Charcoal,

Are we getting a crop mode here? Thanks!

Hello,
Thanks for raising this up. May we know did you set aspect ratio or resolution for Preview use case? And could you also attach the captured image file?

The captured image file is part of the image file that I've already attached (the right part).

I did not set anything on the Preview use case other than the lens facing.

```
val cameraPreview = Preview(Builder()
    .setLensFacing(CameraX.LensFacing.BACK)
    .build())

cameraPreview.setOnPreviewOutputUpdateListener {
  // Every time the viewfinder is updated, recompute the layout. By removing and re-adding it.
  val parent = parent as ViewGroup
  parent.removeView(this)
  parent.addView(this, 0)

  surfaceTexture = it.surfaceTexture
  updateTransform()
}

CameraX.bindToLifecycle(lifecycleOwner, cameraPreview, *useCase)
```
