All Implemented Interfaces:

ColorFormat, Serializable

public class HSLAColorFormat
extends TupleColorFormat

Implements the method ColorFormat of - http://www.w3.org/wiki/CSS/Properties/color/HSLA.
Im using the "HSLColor" implementation of "Rob Camick. - http://www.camick.com" - Source.
The name of the format "hsla" is not case sensitive.

Name	HSLAColorFormat
Format	hsla(hue,saturation,lightness,alpha)
Description	Hue (float)A float - Hue is represented as an angle of the color circle (i.e. the rainbow represented in a circle). This angle is so typically measured in degrees that the unit is implicit in CSS; syntactically, only a is given. By definition red=0=360, and the other colors are spread around the circle, so green=120, blue=240, etc. As an angle, it implicitly wraps around such that -120=240 and 480=120. Saturation A float - Saturation is represented as percentages. 100% is full saturation, and 0% is a shade of gray. Lightness A float - Lightness is represented as percentages. 0% lightness is black, 100% lightness is white, and 50% lightness is "normal". Alpha : A float - the uniform opacity setting. Any values outside the range 0.0 (fully transparent) to 1.0 (fully opaque) will be clamped to this range. (both inclusive).
Example of valid values	hsla(45.2,88.121%,99.112%,0.082) hsla(0,0%,0%,1) hsla(360,100%,100%,1.0) hsla(200 ,78%, 5%,0.55) hsla(360,22%,33%,1) hsla(99,0%,66%,0.1)
