## Discussion

Discussion This method applies the palette filter to an image. The effect uses the palette image that is K x 1 pixels in size containing a set of colors, replacing the image colors. The palettize filter uses the following properties: The following code creates a filter that replaces the colors of the input image with the specified colors found in the palette image: func palettize(inputImage: CIImage, paletteImage: CIImage) -> CIImage {     let palettizeFilter = CIFilter.palettize()     palettizeFilter.inputImage = inputImage     palettizeFilter.paletteImage = paletteImage     palettizeFilter.perceptual = true     return palettizeFilter.outputImage! }
