Coverting RGB -> HLS function

[Taurus99]

Is there any existing function to convert RGB values to HLS (Hue, Luminosity and Saturation)? or existing script? I want to use GetPixelColor and find out the HLS values for it.

Thanks.

You can get some example value's with the _ChooseColor() function. Example:

#include <Misc.au3>
_ChooseColor()

Awesome stuff. I made a slight tweak.

Original Code:

;convert to 0-255 ranges

;h [0-360], h,l [0-1]

$l *= 240

$s *= 240

$h = ($h/360)*240

Replacement Code (switch to 255 as max):

;convert to 0-255 ranges

;h [0-360], h,l [0-1]

$l *= 255

$s *= 255

$h = ($h/360)*255

After that change, its perfectly matches the data in MouseZoom which I use:

Larry, where you found the code, is there's a RGB/HSL conversion to CMYB (Cyan Magena Yellow Black) code?
