Color gradient in HSV space.
| Updraft::Util::Gradient::Gradient | ( | const QColor & | c1, |
| const QColor & | c2, | ||
| bool | reverseHue = false |
||
| ) |
Initialize the gradient with end colors.
| c1 | Color to start at. |
| c2 | Color to stop at. |
| reverseHue | If this is true, then hue is interpolated in the reverse direction -- that means it takes the longer path. Example: Gradient(Qt::red, Qt::green, false) only goes through yellow, while Gradient(Qt::red, Qt::green, true) becomes violet, blue and cyan. |
| Updraft::Util::Gradient::Gradient | ( | ) | [inline] |
Gradients made with this constructor are completely black.
| QColor Updraft::Util::Gradient::get | ( | qreal | t | ) | const |
Return the color at given position.
| t | position in the gradient, t >= 0, t <= 1 |
