1/* Plugin for jQuery for working with colors. 2 * 3 * Version 1.1. 4 * 5 * Inspiration from jQuery color animation plugin by John Resig. 6 * 7 * Released under the MIT license by Ole Laursen, October 2009. 8 * 9 * Examples: 10 * 11 * $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString() 12 * var c = $.color.extract($("#mydiv"), 'background-color'); 13 * console.log(c.r, c.g, c.b, c.a); 14 * $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)" 15 * 16 * Note that .scale() and .add() return the same modified object 17 * instead of making a new one. 18 * 19 * V. 1.1: Fix error handling so e.g. parsing an empty string does 20 * produce a color rather than just crashing. 21 */ 22 23(function($) { 24 $.color = {}; 25 26 // construct color object with some convenient chainable helpers 27 $.color.make = function (r, g, b, a) { 28 var o = {}; 29 o.r = r || 0; 30 o.g = g || 0; 31 o.b = b || 0; 32 o.a = a != null ?

Line numbers count LF bytes from the start of the resource, as the search results do. Vendor segments are library code the classifier recognised; they are stored but not indexed. Bytes are shown as Latin1 characters, one per byte.
