GraphUtil.ColorRGBToHLS Function

Returns a converted color from RGB to HLS.

Pascal

procedure ColorRGBToHLS(clrRGB: TColorRef; var Hue: Word; var Luminance: Word; var Saturation: Word);

C++

ColorRGBToHLS(TColorRef clrRGB, Word Hue, Word Luminance, Word Saturation);

ColorRGBToHLS converts colors from RGB (Red, Green, Blue) to HLS/HBS (Hue, Lightness, Saturation/Hue, Brightness, Saturation).

TColorRef represents the base color.

Hue represents the hue.

Luminance represents the luminance.

Saturation represents the saturation.

Note: Hue, Luminance and Saturation are given by reference. The HLS value is stored in these three variables after the routine ends.
