+=================
+
+Visit: [http://www.daviddurman.com/flexi-color-picker](http://www.daviddurman.com/flexi-color-picker)
+
+Features
+========
+
+- no Flash, images or 1px divs
+- no dependency on an external JavaScript library
+- dimensions of both the picker and the slider areas can be adjusted arbitrarily
+- minimalistic (about 400 loc including comments)
+- support for a large scale of browsers (including mobile browsers)
+- understandable (no magic behind, code can be easily read and therefore adjusted)
+- styleable in CSS
+- position of the slider and the picker areas is not hardcoded and can be changed in CSS
+- HSV, RGB and HEX output/input
+- indicators (pointers to the slider and picker areas) can be arbitrary HTML elements (images, divs, spans, ...) styleable in CSS
+- ready-to-use themes (stored in one CSS stylesheet)
+
+
+Description
+===========
+
+FlexiColorPicker is based on HSV color model. The only two parts of the color picker are therefore
+the **slider** for selecting _hue_ value and the **picker** for selecting _saturation_ and _value_. Both
+the **slider** and **picker** are HTML elements (usually `<div>`'s) that serve as wrappers for SVG/VML gradient
+rectangles. The **slider** gradient rectangle represents the _hue_ value (gradient with 9 `stop-color`s). The
+two overlapping black and white gradient rectangles of the **picker** represent the _saturation_ and _value_ values.
+The top level elements (`<svg>` in case of SVG enabled browser and `<div>` in case of VML enabled browser)
+that wrap each of the **slider** and **picker** gradient rectangles have set `width` and `height` to `100%` which
+means that the color picker components (slider and picker) adjust themselfs automatically to the dimensions of the **slider** and **picker**
+HTML elements.
+
+
+API
+===
+
+**`ColorPicker(colorPickerElement, function(hex, hsv, rgb) { /*do something when the color changes */ })`**
+
+This is the no-hassle form of creating the color picker. This is the recommended call.
+
+Example:
+
+ <div id="mycolorpicker" class="cp-default"></div>
+ <script>
+ ColorPicker(document.getElementById('mycolorpicker'), function(hex, hsv, rgb) {
+ document.body.style.backgroundColor = hex;
+ });
+ </script>
+
+
+**`ColorPicker.prototype.setHsv(hsv)`**
+
+Sets HSV value.
+
+Example:
+
+ var cp = ColorPicker(document.getElementById('mycolorpicker'), function() {});
+ cp.setHsv({ h: 180, s: .2, v: .7 });
+
+**`ColorPicker.prototype.setRgb(rgb)`**
+
+Sets RGB value.
+
+Example:
+
+ var cp = ColorPicker(document.getElementById('mycolorpicker'), function() {});
+ cp.setRgb({ r: 120, g: 205, b: 18 });
+
+
+**`ColorPicker.prototype.setHex(hex)`**
+
+Sets HEX value.
+
+Example:
+
+ var cp = ColorPicker(document.getElementById('mycolorpicker'), function() {});
+ cp.setHex('#AB12FE');
+
+
+**`ColorPicker.positionIndicators(sliderIndicator, pickerIndicator, sliderCoordinate, pickerCoordinate)`**
+
+Positions indicators in the slider and the picker. This is a helper function that is supposed to be called
+in the callback function passed as the fourth argument to the `ColorPicker` function. The only thing it does is
+setting the `top` and `left` CSS coordinate on the `sliderIndicator` and `pickerIndicator` HTML elements.
+If you use the no-hassle form (see above), you don't have to deal with this function at all.
+
+Example:
+
+ ColorPicker(
+ document.getElementById('slider'),
+ document.getElementById('picker'),
+
+ function(hex, hsv, rgb, pickerCoordinate, sliderCoordinate) {
+
+ ColorPicker.positionIndicators(
+ document.getElementById('slider-indicator'),
+ document.getElementById('picker-indicator'),
+ sliderCoordinate, pickerCoordinate
+ );
+
+ document.body.style.backgroundColor = hex;
+ });
+
+
+**`ColorPicker.fixIndicators(sliderIndicator, pickerIndicator)`**
+
+This helper function just sets the `pointer-events` CSS property to `'none'` on both the `sliderIndicator` and
+`pickerIndicator`. This is necessary otherwise any mouse event (click, mousedown, mousemove) triggered
+on the `sliderIndicator` or `pickerIndicator` HTML elements would be cought instead of bypassed to
+the slider and the picker area, hence preventing the color picker to catch these UI events in order to change
+color. As `pointer-events` CSS property is not supported in all browsers, this function might workaround
+this issue in the future. At this time, setting `pointer-events: none` in CSS on the slider and picker indicators
+is equivalent.
+
+Again, if you use the no-hassle form (see above), you don't have to deal with this function at all.
+
+
+Examples
+========
+
+The basic example demonstrates the minimalism of the FlexiColorPicker. More useful examples follow.
+
+Basic
+-----
+
+ <html>
+ <head>
+ <script type="text/javascript" src="colorpicker.js"></script>
+ <style type="text/css">
+ #picker { width: 200px; height: 200px }
+ #slider { width: 30px; height: 200px }
+ </style>
+ </head>
+ <body>
+
+ <div id="picker"></div>
+ <div id="slider"></div>
+
+ <script type="text/javascript">
+
+ ColorPicker(
+
+ document.getElementById('slider'),
+ document.getElementById('picker'),
+
+ function(hex, hsv, rgb) {
+ console.log(hsv.h, hsv.s, hsv.v); // [0-359], [0-1], [0-1]
+ console.log(rgb.r, rgb.g, rgb.b); // [0-255], [0-255], [0-255]
+ document.body.style.backgroundColor = hex; // #HEX
+ });
+
+ </script>
+ </body>
+ </html>
+
+
+Note that you can set arbitrary dimensions, position, border and other CSS properties on the slider and picker
+elements as you would do with any other HTML element on the page.
+
+
+Advanced
+--------
+
+This is an advanced example showing how to work with custom indicators.
+
+ <html>
+ <head>
+ <script type="text/javascript" src="../colorpicker.js"></script>
+ <style type="text/css">
+
+ #picker-wrapper {
+ width: 200px;
+ height: 200px;
+ position: relative;
+ }
+ #slider-wrapper {
+ width: 30px;
+ height: 200px;
+ position: relative;
+ }
+ #picker-indicator {
+ width: 3px;
+ height: 3px;
+ position: absolute;
+ border: 1px solid white;
+ }
+ #slider-indicator {
+ width: 100%;
+ height: 10px;
+ position: absolute;
+ border: 1px solid black;
+ }
+ </style>
+ </head>
+ <body>
+
+ <div id="picker-wrapper">
+ <div id="picker"></div>
+ <div id="picker-indicator"></div>
+ </div>
+ <div id="slider-wrapper">
+ <div id="slider"></div>
+ <div id="slider-indicator"></div>
+ </div>
+
+ <script type="text/javascript">
+
+ ColorPicker.fixIndicators(
+ document.getElementById('slider-indicator'),
+ document.getElementById('picker-indicator'));
+
+ ColorPicker(
+ document.getElementById('slider'),
+ document.getElementById('picker'),
+
+ function(hex, hsv, rgb, pickerCoordinate, sliderCoordinate) {
+
+ ColorPicker.positionIndicators(
+ document.getElementById('slider-indicator'),
+ document.getElementById('picker-indicator'),
+ sliderCoordinate, pickerCoordinate
+ );
+
+ document.body.style.backgroundColor = hex;
+ });
+
+ </script>
+ </body>
+ </html>
+
+
+
+Note how the indicators work. There is no built-in indicators in FlexiColorPicker, instead, the user
+has a freedom to set their own indicators as normal HTML elements styled in CSS (or use one of the ready-to-use themes packaged with FlexiColorPicker).
+
+
+No hassle
+---------
+
+If you don't want to deal with any of the above mentioned details and you're just looking for a copy-paste
+(one function call-like) color picker, see this example.
+
+ <html>
+ <head>
+ <script type="text/javascript" src="../colorpicker.js"></script>
+ <link rel="stylesheet" type="text/css" href="../themes.css" />
+ </head>
+ <body>
+
+ <div id="color-picker" class="cp-default"></div>
+
+ <script type="text/javascript">
+
+ ColorPicker(
+
+ document.getElementById('color-picker'),
+
+ function(hex, hsv, rgb) {
+ console.log(hsv.h, hsv.s, hsv.v); // [0-359], [0-1], [0-1]
+ console.log(rgb.r, rgb.g, rgb.b); // [0-255], [0-255], [0-255]
+ document.body.style.backgroundColor = hex; // #HEX
+ });
+
+ </script>
+ </body>
+ </html>
+
+
+The ColorPicker function has recognized only two arguments which means that it builds the HTML needed for you
+and also fixes and positions indicators automatically.
