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
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 };
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)
