[![Cocoapod compatible](https://img.shields.io/cocoapods/v/hsluv-objc.svg)](https://cocoapods.org/pods/hsluv-objc) [![Build Status](https://travis-ci.org/hsluv/hsluv-objc.svg?branch=master)](https://travis-ci.org/hsluv/hsluv-objc) #hsluv-objc Objective-C port of [HSLuv](http://www.hsluv.org). ##Which files are needed? If you're using [CocoaPods](https://cocoapods.org) just add `pod 'hsluv-objc'` to your Podfile. Otherwise, include this files in your project: - hsluv-objc.h - hsluv-objc+Tests.h - hsluv-objc.c ##How to use Import `hsluv-objc.h`, which defines the following functions: ~~~objective-c // Accepts red, green and blue values between 0 and 1, returns the color in hex format, as in "#012C4A" NSString *rgbToHex(CGFloat red, CGFloat green, CGFloat blue); // Accepts an hex color, as in "#012C4A", and stores its red, green and blue components with values between 0 and 1. BOOL hexToRgb(NSString *hex, CGFloat *red, CGFloat *green, CGFloat *blue); // Hue is a value between 0 and 360, saturation and lightness between 0 and 100. Stores the RGB in values between 0 and 1. void hsluvToRgb(CGFloat hue, CGFloat saturation, CGFloat lightness, CGFloat *red, CGFloat *green, CGFloat *blue); // Red, green and blue values between 0 and 1, stores the hsluv components with hue between 0 and 360, saturation and lightness between 0 and 100. void rgbToHsluv(CGFloat red, CGFloat green, CGFloat blue, CGFloat *hue, CGFloat *saturation, CGFloat *lightness); // Hue is a value between 0 and 360, saturation and lightness between 0 and 100. Stores the RGB in values between 0 and 1. void hpluvToRgb(CGFloat hue, CGFloat saturation, CGFloat lightness, CGFloat *red, CGFloat *green, CGFloat *blue); // Red, green and blue values between 0 and 1, stores the hpluv components with hue between 0 and 360, saturation and lightness between 0 and 100. void rgbToHpluv(CGFloat red, CGFloat green, CGFloat blue, CGFloat *hue, CGFloat *saturation, CGFloat *lightness); ~~~
