## Discussion

Discussion This method applies the edge work filter to an image. The effect creates a stylized black-and-white rendition of the image that looks similar to a woodblock print. The edge work filter uses the following properties: The following code creates a filter that results in a monochrome image with the edges of objects highlighted: func edgeWork(inputImage: CIImage) -> CIImage {     let edgeWorkFilter = CIFilter.edgeWork()     edgeWorkFilter.inputImage = inputImage     edgeWorkFilter.radius = 4     return edgeWorkFilter.outputImage! }
