Allows for the replacement of colors in the image with a palette created from a smooth gradient. Several sample gradients are supplied, and new gradients are simple to create. To create a new color stop in a gradient, double click the area where you'd like the color stop to appear. You may also drag the color stop to the desired location. Change the currently selected color stop's color and position with the controls below the gradient. You may also delete the current color stop by clicking the "Delete Color" button. The square color stops at either end are special and cannot be deleted. You may, however, select them to change their color with the left mouse button. You can invert your gradient, from left to right, by clicking the "Invert" button.
(This screenshot is dithered and color-reduced. The actual effect uses smooth transitions between colors)
Once you have your gradient the way you like it, you may save it for future use. Click the "Save as Preset" button below the gradient and give your gradient a name. It will be saved and will display in the Presets list on subsequent uses. To load a Preset, either double click it in the Presets list or highlight it in the Presets list and press the "Load Selected" button. To permanently remove a Preset from the list, highlight it in the Presets list and press the "Delete Selected" button.
