WFColorCode

Test Status SwiftPM compatible

WFColorCode is a NSColor extension that allows creating NSColor instance from a CSS color code string, or color code string from a NSColor instance. It also adds the ability to handle HSL color space.

  • Requirements: OS X 10.10 or later

Usage

WFColorCode supports the following color code styles.

/// color code type
enum ColorCodeType: Int {
    case hex        // #ffffff
    case shortHex   // #fff
    case cssRGB     // rgb(255,255,255)
    case cssRGBa    // rgba(255,255,255,1)
    case cssHSL     // hsl(0,0%,100%)
    case cssHSLa    // hsla(0,0%,100%,1)
    case cssKeyword // White
};

Example

Import ColorCode to use.

import ColorCode

// create NSColor instance from HSLa color code
var type: ColorCodeType?
let whiteColor = NSColor(colorCode: "hsla(0,0%,100%,0.5)", type: &type)
let hex: String = whiteColor.colorCode(type: .hex)  // => "#ffffff"

// create NSColor instance from HSLa values
let color = NSColor(deviceHue:0.1, saturation:0.2, lightness:0.3, alpha:1.0)

// create NSColor instance from a CSS3 keyword
let ivoryColor = NSColor(colorCode: "ivory")

// get HSL values from NSColor instance
var hue: CGFloat = 0
var saturation: CGFloat = 0
var lightness: CGFloat = 0
var alpha: CGFloat = 0
color.getHue(hue: &hue, saturation: &saturation, lightness: &lightness, alpha: &alpha)
