# captureDevicePointConverted(fromLayerPoint:)

Converts a point from layer coordinates to the coordinate space of the capture device.

## Declaration

```swift
func captureDevicePointConverted(fromLayerPoint pointInLayer: CGPoint) -> CGPoint
```

## Parameters

- `pointInLayer`: A point in layer coordinates to convert.

## Return Value

Return Value A point in capture device coordinates.

## Discussion

Discussion A capture device’s focusPointOfInterest and exposurePointOfInterest properties provide a CGPoint value where {0,0} represents the top-left and {1,1} represents the bottom-right of the unrotated image. The conversion performed by this method takes the layer’s frame size and its videoGravity into consideration.
