Un degradado es un conjunto de colores ordenados linealmente. El uso más básico de los degradados se realiza con la herramienta Mezcla, a veces llamada la herramienta de degradado o la herramienta de relleno de degradado: funciona rellenando la selección con los colores de un degradado. Tiene muchas opciones a elegir para controlar la forma en que los colores del degradado se disponen dentro de la selección. También hay otras formas importantes de usar los degradados, incluyendo:

Pintar con degradado

Cada una de las herramientas de pintura básicas de GIMP le permite la opción de usar los colores de un degradado. Esto le permite crear trazos de pincel que cambian el color de una punta a la otra.

El filtro mapa de degradado

This filter is in the Colors menu, and allows you to colorize an image, using the color intensity of each point with the corresponding color from the active gradient (the intensity 0, very dark, is replaced by the color at most left end of the gradient, progressively until the intensity is 255, very light, replaced by the most right color of the gradient. See Sección 8.39, “Mapa de degradado” for more information.

GIMP comes presupplied with a large number of gradients. You can also add new gradients that you create or download from other sources. You can access the full set of available gradients using the Gradients dialog, a dockable dialog that you can either activate when you need it, or keep around as a tab in a dock. The current gradient, used in most gradient-related operations, is shown in the Brush/Pattern/Gradient area of the Toolbox. Clicking on the gradient symbol in the Toolbox is an alternative way of bringing up the Gradients dialog.

Some quick examples of working with gradients (for more information see Gradient Tool) are:

Algunas cosas útiles que saber sobre los degradados de GIMP:

The gradients that are supplied with GIMP are stored in a system gradients folder.

Gradients that you create are automatically saved in the gradients folder of your personal GIMP directory. Any gradient files (ending with the extension .ggr) found in one of these folders, will automatically be loaded when you start GIMP. You can add more directories to the gradient search path, if you want to, in the Gradients tab of the Data Folders section of the Preferences dialog.

GIMP can also load gradient files in SVG format, used by many vector graphics programs. To make GIMP load an SVG gradient file, place it in the gradients folder of your personal GIMP directory, or any other folder in your gradient search path.
