colorPicker

An advanced color picker (desktop use) using Colors for color conversion / calculation... All the W3C 2.0 calculations are also based on alpha levels on all layers Supported color spaces: (*: also displayed as colors) rgb * hsv(b) * hsl * cmyk cmy Lab XYZ HEX

Convertions of 182 color space combinations (rgb2HSV, RGB2hsl, rgb2RGB, HEX2Lab, ...)

See demo at http://dematte.at/cpn

var myColors = new Colors({ // all options have a default value... color: 'rgba(204, 82, 37, 0.8)', // initial color (#RGB, RGB, #RRGGBB, RRGGBB, rgb(r, g, b), ...) XYZMatrix: ..., // Observer = 2° (CIE 1931), Illuminant = D65 --- see source for dedtails XYZReference: ..., // back reference to XYZMatrix --- see source for dedtails grey: {r: 0.298954, g: 0.586434, b: 0.114612}, // CIE-XYZ 1931 luminance: {r: 0.2126, g: 0.7152, b: 0.0722}, // W3C 2.0 valueRanges: {rgb: {r: [0, 255], g: [0, 255], b: [0, 255]}, hsv:...}, // skip ranges if no conversion required customBG: '#808080' // the solid bgColor behind the chosen bgColor (saved color) convertCallback: function(colors, type){}, // callback function after color convertion for further calculations... allMixDetails: false // if set to true, Colors deliveres some more mixed layer informations for all color layers });

colorPicker uses an instance of Colors and passes the options to it, so some values are the same...

var myColorPicker = new ColorPicker({ color: ..., // see Colors... mode: 'rgb-b', // initial mode the color picker is starting with fps: 60, // the framerate colorPicker refreshes the display if no 'requestAnimationFrame' delayOffset: 8, // pixels offset when shifting mouse up/down inside input fields before it starts acting as slider CSSPrefix: 'cp-', // the standard prefix for (almost) all class declarations (HTML, CSS) size: 0, // one of the 4 sizes: 0 = L (large), 1 = S, 2 = XS, 3 = XXS; resize to see what happens... scale: 1, // only used internaly if size changes... (should't be here) allMixDetails: true, // see Colors... alphaBG: 'w' // initial 3rd layer bgColor (w = white, c = custom (customBG), b = black); customBG: '#808080' // see Colors... noAlpha: true, // disable alpha input (all sliders are gone and current alpha therefore locked) cmyOnly: false, // display CMY instead of CMYK memoryColors: [{r: 100, g: 200, b: 10, a: 0.8}, ...] // array of colors in memory section opacityPositionRelative: undefined, // render opacity slider arrows in px or % customCSS: undefined, // if external stylesheet, internal will be ignored... appenTo: document.body, // the HTMLElement the colorPicker will be appended to on initialization noRangeBackground: false, // performance option: doesn't render backgrounds in input fields if set to false textRight: false, // not supported yet. Make numbers appear aligned right noHexButton: false, // button next to HEX input could be used for some trigger... noResize: false, // enable / disable resizing of colorPicker noRGBr: false, // active / passive button right to RGB-R display. Disables rendering of 'real' color possibilities... noRGBg: false, // same as above noRGBb: false, // same as above CSSStrength: 'div.', // not in use XYZMatrix: ..., // see Colors... XYZReference: ..., // see Colors... grey: ..., // see Colors... luminance: ..., // see Colors... renderCallback: // function(colors, mode){}, // callback on after rendering (for further rendering outside colorPicker) actionCallback: function(e, action){}, // callback on any action within colorPicker (buttons, sliders, ...) convertCallback: function(colors, type){}, // see Colors... });

After initializing Color or ColorPicker you'll get a clean but rhich model of the instance:

Color: { colors: {all kinds of color values...}, options: {all the options you set or that are set as default...}, proto: { // all methods Color uses setColor: function(newCol, type, alpha) {}, getColor: function(type) {}, setCustomBackground: function(col) {}, saveAsBackground: function() {}, convertColor: function(color, type) {} // converts 182 different combinations } }

ColorPicker: { color: { // instance of Color inside colorPicker colors: {all kinds of color values...}, options: {all the options you set or that are set as default...} }, nodes: {all kinds of cashed nodes, textNodes and styles, etc...}, proto: { // all methods ColorPicker uses setColor: function(newCol, type, alpha, forceRender) {}, startRender: function(oneTime) {}, stopRender: function() {}, setCustomBackground: function(col) {}, saveAsBackground: function() {}, setMode: function(mode) {}, destroyAll: function() {} } }

The klass ColorPicker has some functions attached, used inside, exported for convenience...

ColorPicker.addEvent = function(obj, type, func){}; // with built in cashe ColorPicker.removeEvent = function(obj, type, func){}; ColorPicker.getOrigin = function(elm){}; ColorPicker.limitValue = function(value, min, max){}; ColorPicker.changeClass = function(elm, cln, newCln){}; // a bit tricky to use...
