Gradients from top to bottom: FG to BG (RGB); Full Saturation Spectrum CCW; Nauseating Headache; Browns; Four Bars


Un Degradeu este un set de culori aranjate într-o ordine liniară. Utilizarea cea mai de bază a degradeului este de Instrument degradeu, uneori cunoscut sub numele de Instrument de umplere degradeu: acesta funcționează prin completarea selecției cu culori dintr-un degradeu. Aveți mai multe opțiuni pentru a alege modul de control în care culorile degradeu sunt aranjate în cadrul selecției. Există, de asemenea, alte moduri importante de a utiliza degradeuri, inclusiv:

Desenarea cu un degradeu

Fiecare dintre instrumentele de bază de desen GIMP vă permite opțiunea de a folosi culori dintr-un degradeu. Acest lucru vă permite să creați tușe care își schimba culoarea de la un capăt la altul.

Filtrul Hartă de degradeu

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 Secțiune 8.39, „Hartă degrade” 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:

Câteva lucruri utile de a fi știute despre degradeurile din 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.

You can find a large number of interesting SVG gradients on the web, in particular at OpenClipArt Gradients [OPENCLIPART-GRADIENT].
