Description

Converts RGB values specified by R, G and B to color components within the HSL color space and returns them in H, S and L. The HSL values are defined as percentages within the range 0..100. The resulting values can be converted back to RGB values using HSLToRGB.

Example

var
  H, S, L: Extended;

begin
  RGBtoHSL(0, 255, 0, H, S, L);
  WriteLn(FloatToStr(H) + ';' + FloatToStr(S) + ';' + FloatToStr(L));
end.

Output:

33,3333343267441;100;50
