### 3.4.6 The Gradients-Subdialog

This subdialog of the Color Editor allows you to create and modify gradients. Furthermore, you can add colors to the gradient list by dragging and delete gradients from the list by using its context menu.

At the top left there is a color field that displays the active color. Right next to it are the gradient settings:

- the gradient type
There are Linear, Circle, Radial Reflected and Radial.
If the type is Circle, you can change the vertical scaling of the gradient via the text box below the color field. The circle will be transformed to an ellipse.
- The color model
Gradients can be calculated in the color model of the document, in HIS and in Lab.
- The repetition mode
Here you can control whether a gradient should stop at its endpoints or whether it should be repeated.
- The interpolation
You can use Linear Interpolation and Cubic Interpolation. With cubic interpolation the color change is softer at the single color stops.

At the top right, there is a field that defines the position of the gradient. This position is relative to the layer to which the gradient will be applied. If you hold down the Alt key while moving a position, it will snap to the edges and center.

The color bar defines the colors of the gradient. The small color fields below the bar can be moved with the mouse. If a color field is dragged outside the bar, it will be deleted. By clicking at a location with no field a new one is created. If the Ctrl-key (Windows) or the Command-key (macOS) is pressed while clicking, the color field will get the corresponding color from the color bar. By double-clicking a color field, it can be edited with the Color Editor (see chapter 3.4). The Color Editor allows to modify the transparency of the given color, too.

The context menu of the color fields shows a list with predefined colors, the context menu of the whole bar offers additional functions, that are explained in the following.
