A library for extracting color from an image.
The DominantColors makes it easy to find the dominant colors of the image. It returns a color palette of the most common colors in the image.
Get the colors according to the standard settings:
let cgColors = try DominantColors.dominantColors(image: cgImage)Get colors by selecting algorithm. Extract colors by specifying the color difference formula:
let formula: DeltaEFormula = .CIE94
let algorithm: DominantColorAlgorithm = .iterative(formula: formula)
let cgColors = try DominantColors.dominantColors(image: cgImage, algorithm: algorithm)Get colors with options:
let flags: [DominantColors.Flag] = [.excludeBlack]
let cgColors = try DominantColors.dominantColors(image: cgImage, flags: flags)Get the average color by dividing the image into segments horizontally:
let count: UInt8 = 8
let cgColors = try DominantColors.dominantColors(image: cgImage, algorithm: .areaAverage(count: count))Use the macOS example ImageColors project included in this repository to find examples of various DominantColors features.
The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.
Once you have your Swift package set up, adding DominantColors as a dependency is as easy as adding it to the dependencies value of your Package.swift.
