Availability
SCAR Divi 3.00 > Current
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 result 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
