toHSL method

@override HSLColour toHSL()

Converts this colour to its HSLColour representation.

Implementation

@override
HSLColour toHSL() {
  double s = 0.0;
  double l = 0.0;
  l = (2 - saturation) * value / 2;
  if (l != 0) {
    if (l == 1) {
      s = 0.0;
    } else if (l < 0.5) {
      s = saturation * value / (l * 2);
    } else {
      s = saturation * value / (2 - l * 2);
    }
  }
  return HSLColour.fromAHSL(alpha, hue, s.clamp(0.0, 1.0), l.clamp(0.0, 1.0));
}
