Platform agnostic color Library.

Usage

import GenericColor

Initialization

// Initialize with byte value via .byte(_) method
letcolor1=Color<RGB>(
red:.byte(221),
green:.byte(51),
blue:.byte(12),
alpha:.byte(255))
// or directly via numeric literals and .raw(_) method for numerics
letalpha=1letcolor2=Color<RGB>(
red:.max, green:0.2, blue:.byte(12),
alpha:.raw(alpha))print(color1 == color2) // true
// hex initialization is supported for RGB color space
// - works with "#" prefix and without, case-insensitive
// - works with rgb, rgba, rrggbb, rrggbbaa representations
// - avalible trough .hex and .init(hex:)
Color.hex("FA6878") // Type == Color<RGB>?
Color(hex:"#aaaf") // rgba, the same as #AAAAAAFF
// or use hex literals
Color(rgb:0xfa6878)Color(rgba:0xfa6878ff)Color.rgb(0xAAAAAA)
// you can also get an rgb hex value of any color
color1.hex()
color2.hex(uppercased:true)
color3.hex(hashTagPrefix:true)
// color literals will work too, but accuracy is not guarantied
letliteral:Color<RGB>= #colorLiteral(red:0.9803921568627451, green:0.40784313725490196, blue:0.47058823529411764, alpha:1)

ColorSpaces

letcolor1=Color<RGB>()letcolor2=Color<HSB>()letcolor3=Color<CMYK>()
// Implicit convertions
print(color1.convert()== color2)print(color1.convert()== color3)print(color2.convert()== color1)
// Explicit convertions
print(color1.convert(to:HSB.self)== color2)print(color1.convert(to:CMYK.self)== color3)print(color2.convert(to:RGB.self)== color1)
// Container mappings
print(color2.map(to: \.cmyk)== color3)print(color3.map(to: \.rgb)== color1)print(color3.map(to: \.hsb)== color2)
// Color flat mappings
print(color1.flatMap{ $0.with(alpha:1)})

Installation

Add the package to Your SwiftPM package dependencies:

.package(
name:"swift-generic-color",
url:"https://github.com/capturecontext/swift-generic-color.git",.upToNextMinor(from:"0.5.0"))

then add GenericColor dependency to your target

.product(
name:"GenericColor",package:"GenericColor")
