intellijel YaBB Newbies Offline Posts: 37	convert RGB to HSB in a range Jan 27th, 2010, 9:31am   I am using HSB colormode but the values are in the range of 0-100 instead of 0-1. How can I convert RGB values in the range of 0-255 to HSB values? I can use the Java function Color.RGBtoHSB but I am not clear what range of values it converts to?

Re: convert RGB to HSB in a range Reply #1 - Jan 27th, 2010, 9:54am   Yes, RGBtoHSB method isn't very well documented, you will find some elements of answer in the sibling function HSBtoRGB: "The saturation and brightness components should be floating-point values between zero and one (numbers in the range 0.0-1.0). The hue component can be any floating-point number. The floor of this number is subtracted from it to create a fraction between 0 and 1. This fractional number is then multiplied by 360 to produce the hue angle in the HSB color model."
