flexi-color-picker

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:

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
-----

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.

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.

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.
