Gradient Fill

The Gradient Fill tool lets you apply blended color fills to a layer.


The basic tool settings are shown in the Tool Options panel above the Image Window or by right-clicking on the image. To display the full list of parameters, press the tool icon in the Tool Options panel or use the F5 key. To specify the parameter settings, enter a numerical value in the parameter’s field or use the slider.


After the gradient is created, you can edit it using the options in the Tool Options panel. Using the gradient line you can increase the number of gradient colors and adjust the color and transparency of the gradient components.

To add colors to the gradient, click on the gradient line in the Image Window. To remove a color point from the gradient, drag it aside and release the mouse button.

To adjust the color, transparency and position of the gradient points, call the menu by right-clicking on a point.

Gradient Point Settings Menu

Using the gradient line you can specify the color of the point. Also, you can use the color selection dialog, which is displayed by clicking on the color square.

The Color check-box indicates whether the point displays the selected color shown in the square box to the right. Smaller squares represent the last five colors used when creating the gradient. If the check-box is disabled, the color of this point is determined depending on adjacent pixels and cannot be changed.

The Opacity (0-100) check-box controls the transparency of the gradient at that point. If the Opacity value is less than the maximum, the transparency of the gradient varies smoothly from point to point. If the check-box is disabled, the transparency of the gradient at that point cannot be changed and depends on the total opacity of the gradient.

Using the Position (0-100) parameter you can specify the exact position of each point of the gradient.


You can save the gradient to use it in the future. Click on the tool's icon in the Tool Options panel to see the full list of gradients.
