Color lemon::distantColor | ( | const Color & | c | ) | [inline] |
Returns a Color which is as different from the given parameter as it is possible.
Color lemon::distantBW | ( | const Color & | c | ) | [inline] |
Returns black for light colors and white for the dark ones.
bool lemon::isNaN | ( | double | v | ) | [inline] |
This function checks whether the parameter is NaN or not. Is should be equivalent with std::isnan(), but it is not provided by all compilers.
