## Declaration

```swift
func layerRectConverted(fromMetadataOutputRect rectInMetadataOutputCoordinates: CGRect) -> CGRect
```

## Parameters

- `rectInMetadataOutputCoordinates`: A rectangle in the doc://com.apple.avfoundation/documentation/AVFoundation/AVCaptureMetadataOutput coordinate system.

## Return Value

Return Value A rectangle in the preview layer’s coordinate system.

## Discussion

Discussion A metadata capture output’s rectOfInterest a CGRect value where {0,0} represents the top-left of the picture area, and {1,1} represents the bottom-right on an unrotated image. The system takes the layer’s frame size and its videoGravity into consideration when making the conversion.
