<p>
A javascript color picker. The wheel is drawn using the Raphael js library. jQuery is used to assist with events.
The wheel size is set on creation. It supports a small set of callbacks and touch events.
</p>
<p>
It was created for the UI at <a href="http://famedriver.com">Fame Driver</a> and distributed with a MIT license.

<h2>Usage and methods</h2>
<div class="method">
<b>var cw = Raphael.colorwheel(dom_element, height_width [, segments]);</b>
<div>The wheel is drawn into a square, so only one dimension is required. <b>segments</b> is an option to increase, or decrease, the smoothness of the hue ring. 60 is the default.</div>
</div>
<div class="method">
<b>cw.input(dom_element)</b> <span class="returns">⇒ cw</span>
<div>Binds a text input for setting and receiving the color as a hex value. This will allow the user to input a hex value and update the wheel.</div>
</div>
<div class="method">
<b>cw.onchange(callback)</b> <span class="returns">⇒ cw</span>
<div>Set a callback for any change received. Callback takes one argument, a Raphael RGB color object.</div>
</div>
<div class="method">
<b>cw.ondrag(start, stop)</b> <span class="returns">⇒ cw</span>
<div>Set a start and stop callback for dragging. The callbacks take one argument, a Raphael RGB color object.</div>
</div>
<div class="method">
<b>cw.color()</b> <span class="returns">⇒ Raphael color object</span>
<div>Get the current color as RGB object</div>
</div>
<div class="method">
<b>cw.color(hex_value)</b> <span class="returns">⇒ cw</span>
<div>Set the current color via a hex value</div>
</div>
<div class="method">
<b>cw.color_hsb()</b> <span class="returns">⇒ Raphael color object</span>
<div>Get the current color as HSB object</div>
</div>
<div class="method">
<b>cw.color_hsb(hsb_object)</b> <span class="returns">⇒ cw</span>
<div>Set the current color via a Raphael h, s, b object</div>
</div>
</div>
<div id="input_example" class="example">
<h2>Input</h2>
<p>Assigning an input to a colorwheel will allow the user to directly change the hex color value.</p>
<p>When the input is set the colorwheel will set its color to the input's value</p>
