Gradient Editor

With this editor you can define and change color ranges within the palette. It can be opened by either selecting the corresponding entry in the menu Colors or double clicking on the gradient display in the main window.
A color range (gradient) is a group of color palette entries either selected by a start and an end color index within the color palette or by arranging different colors manually.

Gradients that define a linear range of entries in the platte can be used for color cycling. This way you can create images that animate flows like waterfalls or just do a cycling color effect.
For this purpose you have the Color Cycling Speed slider. Here you can give each gradient a unique speed value. This value is defined in steps per second and can go from 0 to 100. To see such color cycling animation on the canvas you can define a cycling speed and start playing back the cycling in the gradient panel of the main window or by just hitting the asterisk key on the numeric keyboard. This playback can stay enabled while you are drawing.
To quickly change the cycling speed of gradients please see the gradient management dialog. Be sure not to overlap gradients that are cycled. Otherwise you will get wrong results!

If you created an image that uses gradient color cycling then you can turn it into an animation that stores to file by using Create from Color Cycling in menu Animation.
A simple color cycling sample looks like this:

As soon as a gradient has distinct entries it can be used for Shade and Multi Shade, see menu Mode.

To edit a gradient you can Define Colors based on the color palette that opens. Select a linear range or single color entries and add them as gradient slots.
When done you can select and move them around in the slot area. Hold Ctrl and click on color slots to select entries to drag the around or to remove them again. When you hold Shift and click on a slot then all entries between the first and last clicked entry are selected.

Besides defining fixed colors you can also Add Auto Slots. These gradient positions are filled with the best matching color from the palette when considering a color ramp from the first to the second surrounding color. The are updated automatically on palette entry modifications.

At the Functions button you can find the following tools:
Fixate Auto Slots turns auto slots into fixed ones that do not continue finding best matching colors but use the current ones permanently.

Flip switches the color slot order.

Sort will order all colors by the selected criteria.

Reset will undo all changes.

Clear removes all color slots

Edit Palette lets you directly modify the current color palette. So you can shift colors around or create ramps.

The Preview shows the gradient on a larger area. You may select dithering modes Random or Ordered to increase the virtual color depth. This setting only affects this preview. If you want to enable dithering when using the gradient for filling an object then you must set up dithering in the corresponding fill settings.
