```

## Return Value

## Discussion

Discussion This method applies the vignette effect filter to an image. This effect reduces brightness of the image at the periphery of a specified region. The vignette effect filter uses the following properties: The following code creates a filter that darkens the edges of an area on the input image: func vignetteEffect(inputImage: CIImage ) -> CIImage {     let vignetteFilter = CIFilter.vignetteEffect()     vignetteFilter.inputImage = inputImage     vignetteFilter.intensity = 1     vignetteFilter.radius = 650     vignetteFilter.falloff = 0.5     vignetteFilter.center = CGPoint(x: 1024, y: 768)     return vignetteFilter.outputImage! }
