Unsolved Sort HSL colors
-
Hello, I would like some help to write an algorithm to sort HSL colors from an 512 colors.
I understood that I had to use the hue, saturation and lightness values to order the colors, but I can not get a gradient.
Do you have an example or an indication to give me?
Thanks in advance.

use std::sort with a custom
Comparer
that gives hsl as input

Hello thanks for your reply.
I alreay use this function for sort the QVector<QColor> but the result is not very good.
The best result is this comparaison :
int compare(const QColor &a, const QColor &b) { return a.rgb() < b.rgb(); }
I wrote this code, but the colors the sort does not give a result does not give a gradient.
int compare(const QColor &a, const QColor &b) { if(a.hue() == b.hue()) { if(a.saturation() == b.saturation()) { return (a.lightness() <= b.lightness()); } return (a.saturation() <= b.saturation()); } return (a.hue() < b.hue()); }
