## Discussion

Discussion This method applies the spotlight filter to an image. The effect applies a directional spotlight effect to an image while creating a transparent area not highlighted by the spotlight. The spotlight filter uses the following properties: The following code creates a filter that results in only the bottom left of the image becoming visible while the rest of the image gradually becomes transparent: func spotlight(inputImage: CIImage) -> CIImage {     let spotlightFilter = CIFilter.spotLight()     spotlightFilter.inputImage = inputImage     spotlightFilter.lightPointsAt = CIVector(x: 100, y: 100)     spotlightFilter.brightness = 10     spotlightFilter.lightPosition = CIVector(x: 100, y: 100)     spotlightFilter.concentration = 20     return spotlightFilter.outputImage! }
