Color conversions
« on: July 10, 2011, 09:18:36 pm »
I would like to have the ability to change RGB to HTML (hex) and back to RGB again. But what I would really like is RGB to HSL and back to RGB again.  :)

//edit: Why HSL? Because than I can do color overlay effects like in Gimp.

What would also be nice is an operator on colors. For example that I do this:

Code: [Select]
sf::Color test(20,20,20);

test = test * 1.5;


and we get a brighter test color.  :)

I think that a custom function would be the best...

If SFML won't support it, do you perhaps have the c++ code for that (RGB <-> HSL)? I tried google, but got strange C# stuff...
