/* Plugin for jQuery for working with colors. * * Version 1.1. * * Inspiration from jQuery color animation plugin by John Resig. * * Released under the MIT license by Ole Laursen, October 2009. * * Examples: * * $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString() * var c = $.color.extract($("#mydiv"), 'background-color'); * console.log(c.r, c.g, c.b, c.a); * $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)" * * Note that .scale() and .add() return the same modified object * instead of making a new one. * * V. 1.1: Fix error handling so e.g. parsing an empty string does * produce a color rather than just crashing. */ (function($) { $.color = {}; // construct color object with some convenient chainable helpers $.color.make = function (r, g, b, a) { var o = {}; o.r = r || 0; o.g = g || 0; o.b = b || 0; o.a = a != null ? a : 1; o.add = function (c, d) { for (var i = 0; i < c.length; ++i) o[c.charAt(i)] += d; return o.normalize(); }; o.scale = function (c, f) { for (var i = 0; i < c.length; ++i) o[c.charAt(i)] *= f; return o.normalize(); }; o.toString = function () { if (o.a >= 1.0) { return "rgb("+[o.r, o.g, o.b].join(",")+")"; } else { return "rgba("+[o.r, o.g, o.b, o.a].join(",")+")"; } }; o.normalize = function () { function clamp(min, value, max) { return value < min ? min: (value > max ? max: value); } o.r = clamp(0, parseInt(o.r), 255); o.g = clamp(0, parseInt(o.g), 255); o.b = clamp(0, parseInt(o.b), 255); o.a = clamp(0, o.a, 1); return o; }; o.clone = function () { return $.color.make(o.r, o.b, o.g, o.a); }; return o.normalize(); } // extract CSS color property from element, going up in the DOM // if it's "transparent" $.color.extract = function (elem, css) { var c; do { c = elem.css(css).toLowerCase(); // keep going until we find an element that has color, or // we hit the body or root (have no parent) if (c != '' && c != 'transparent') break; elem = elem.parent(); } while (elem.length && !$.nodeName(elem.get(0), "body")); // catch Safari's way of signalling transparent if (c == "rgba(0, 0, 0, 0)") c = "transparent"; return $.color.parse(c); } // parse CSS color string (like "rgb(10, 32, 43)" or "#fff"), // returns color object, if parsing failed, you get black (0, 0, // 0) out $.color.parse = function (str) { var res, m = $.color.make; // Look for rgb(num,num,num) if (res = /rgb\(\s*([0-9]{1,3})\s*,\s*([0-9]{1,3})\s*,\s*([0-9]{1,3})\s*\)/.exec(str)) return m(parseInt(res[1], 10), parseInt(res[2], 10), parseInt(res[3], 10)); // Look for rgba(num,num,num,num) if (res = /rgba\(\s*([0-9]{1,3})\s*,\s*([0-9]{1,3})\s*,\s*([0-9]{1,3})\s*,\s*([0-9]+(?:\.[0-9]+)?)\s*\)/.exec(str)) return m(parseInt(res[1], 10), parseInt(res[2], 10), parseInt(res[3], 10), parseFloat(res[4])); // Look for rgb(num%,num%,num%) if (res = /rgb\(\s*([0-9]+(?:\.[0-9]+)?)\%\s*,\s*([0-9]+(?:\.[0-9]+)?)\%\s*,\s*([0-9]+(?:\.[0-9]+)?)\%\s*\)/.exec(str)) return m(parseFloat(res[1])*2.55, parseFloat(res[2])*2.55, parseFloat(res[3])*2.55); // Look for rgba(num%,num%,num%,num) if (res = /rgba\(\s*([0-9]+(?:\.[0-9]+)?)\%\s*,\s*([0-9]+(?:\.[0-9]+)?)\%\s*,\s*([0-9]+(?:\.[0-9]+)?)\%\s*,\s*([0-9]+(?:\.[0-9]+)?)\s*\)/.exec(str)) return m(parseFloat(res[1])*2.55, parseFloat(res[2])*2.55, parseFloat(res[3])*2.55, parseFloat(res[4])); // Look for #a0b1c2 if (res = /#([a-fA-F0-9]{2})([a-fA-F0-9]{2})([a-fA-F0-9]{2})/.exec(str)) return m(parseInt(res[1], 16), parseInt(res[2], 16), parseInt(res[3], 16)); // Look for #fff if (res = /#([a-fA-F0-9])([a-fA-F0-9])([a-fA-F0-9])/.exec(str)) return m(parseInt(res[1]+res[1], 16), parseInt(res[2]+res[2], 16), parseInt(res[3]+res[3], 16)); // Otherwise, we're most likely dealing with a named color var name = $.trim(str).toLowerCase(); if (name == "transparent") return m(255, 255, 255, 0); else { // default to black res = lookupColors[name] || [0, 0, 0]; return m(res[0], res[1], res[2]); } } var lookupColors = { aqua:[0,255,255], azure:[240,255,255], beige:[245,245,220], black:[0,0,0], blue:[0,0,255], brown:[165,42,42], cyan:[0,255,255], darkblue:[0,0,139], darkcyan:[0,139,139], darkgrey:[169,169,169], darkgreen:[0,100,0], darkkhaki:[189,183,107], darkmagenta:[139,0,139], darkolivegreen:[85,107,47], darkorange:[255,140,0], darkorchid:[153,50,204], darkred:[139,0,0], darksalmon:[233,150,122], darkviolet:[148,0,211], fuchsia:[255,0,255], gold:[255,215,0], green:[0,128,0], indigo:[75,0,130], khaki:[240,230,140], lightblue:[173,216,230], lightcyan:[224,255,255], lightgreen:[144,238,144], lightgrey:[211,211,211], lightpink:[255,182,193], lightyellow:[255,255,224], lime:[0,255,0], magenta:[255,0,255], maroon:[128,0,0], navy:[0,0,128], olive:[128,128,0], orange:[255,165,0], pink:[255,192,203], purple:[128,0,128], violet:[128,0,128], red:[255,0,0], silver:[192,192,192], white:[255,255,255], yellow:[255,255,0] }; })(jQuery);
