Converting from HSV (HSB in Java) to RGB without using java.awt.Color (disallowed on Google App Engine)

Question

I figured I should post this question, even if I have already found a solution, as a Java implementation was not readily available when I searched for it.

Using HSV

Answer 1

Use ColorUtils which provides

HSLToColor(float\[\] hsl) 

And

[RGBToHSL(int r, int g, int b, float\[\] hsl)]

Methods which are very easy to convert to each other!

For example:

float[] hsl = new float[]{1.5, 2.0, 1.5};
int color = ColorUtils.HSLToColor(hsl);

Now get the color

float[] hslStub = new float[3];
float[] hslFromColor = ColorUtils.colorToHSL(color, hslStub);

Now get the hsl

Here is the sourcecode.
