# lensDistortionCenter

The offset of the distortion center of the camera lens from the top-left corner of the image.

## Declaration

```swift
var lensDistortionCenter: CGPoint { get }
```

## Discussion

Discussion Due to geometric distortions in the image, the center of the distortion may not be equal to the optical center (principal point) of the lens. When making an image rectilinear, use the distortion center rather than the optical center of the image.
