1.1. Introduction

GIMP provides a comprehensive toolbox in order to quickly perform basic tasks such as making selections or drawing paths. The many tools contained within GIMP's toolbox are discussed in detail here.

(In case you're curious, in GIMP lingo a "tool" is a way of acting on an image that requires access to its display, either to let you indicate what you want to do by moving the pointer around inside the display, or to show you interactively the results of changes that you have made. But if you want to think of a tool as a saw, and an image as a piece of wood, it probably won't do you a great deal of harm.)

[Pastaba] Pastaba

See Main Windows: The Toolbox for an overview of the toolbox and its components.

GIMP has a diverse assortment of tools that let you perform a large variety of tasks. The tools can be thought of as falling into the following categories:

  • Selection tools, which specify or modify the portion of the image that will be affected by subsequent actions;

  • Paint tools, which alter the colors in some part of the image;

  • Transform tools, which alter the geometry of the image;

  • Color tools, which alter the colors in the image as a whole;

  • Other tools, which don't fall into the other categories.

1.2. Tool Icons

With GIMP-2.10.18, tool icons can be grouped, and this option is enabled by default. Tools groups are marked with a small dark triangle at the bottom right corner of the icon. The group icon displayed is the first icon in the group. Right click on the group icon to display the list of tools in the group.

You can get the former display back unchecking the Use tool groups option in Skyrius 6.13, „Įrankinė“.

Pav. 14.1. The Tool Icons in the Toolbox

The Tool Icons in the Toolbox

Use tool groups option unchecked. The default order of tools in the toolbox is different since GIMP-2.10.8; you can customize it in the Toolbox Preferences.

Most tools can be activated by clicking on an icon in the Toolbox. By default, some tools are accessible only via the menus. Every tool can be activated from the Tools menu (or the Colors menu for some color tools). Most tools can also be activated from the keyboard using an accelerator key.

In the default setup, created when GIMP is first installed, not all tools show icons in the Toolbox: some tools are omitted. You can customize the set of tools that are shown in the Toolbox in the Toolbox Preferences.

There are two reasons you might want to do this: first, if you only rarely use a tool, it might be easier to find the tools you want if the distracting icon is removed; second, if you use tools that are not found in the toolbox by default, you might find it convenient to have icons for them easily available. In any case, you can always access any tool at any time using the Tools or Colors menu from the main menu.

The shape of the cursor changes when it is inside an image, to one that indicates which tool is active (if in Preferences you have set Image WindowsMouse PointersPointer modeTool icon).

Pav. 14.2. Color and Indicator Area in the Toolbox

Color and Indicator Area in the Toolbox

By default, only the Foreground/Background Colors area is visible. You can add the Brush/Pattern/Gradient area and Active Image area through EditPreferencesToolbox: Skyrius 6.13, „Įrankinė“.

1.3.1. Foreground/Background Colors Area

Pav. 14.3. Foreground/Background Colors Area in the Toolbox

Foreground/Background Colors Area in the Toolbox

Spalvos sritis

The color area shows GIMP's current foreground and background colors, which are used for painting, filling, and many other operations. Clicking on either one of them brings up a color selector dialog that allows you to change to a different color.

Numatytosios spalvos

Clicking on the small symbol in the lower left corner resets the foreground and background colors to black and white. Pressing the D key has the same effect.

Swap Foreground/Background colors

Clicking on the double-headed arrow symbol swaps the foreground and background colors. Pressing the X key has the same effect.

Galite spustelėti ir vilkti vieną iš šių spalvų tiesiai į sluoksnį – bus nuspalvintas visas sluoksnis.

1.3.2. Brush/Pattern/Gradient Area

Pav. 14.4. Active Brush, Pattern and Gradient Area in the Toolbox

Active Brush, Pattern and Gradient Area in the Toolbox

Šioje įrankinės dalyje rodomas dabar pasirinktas teptukas, raštas ir gradientas. Spustelėjus bet kurį iš jų atveriamas dialogas, kuriame galite jį pakeisti.

1.3.3. Active Image Area

Pav. 14.5. Active Image Area in the Toolbox

Active Image Area in the Toolbox

A thumbnail of the active image is displayed in this area. If you click on this thumbnail, the Images dialog is opened. This can be useful if you have many images on your screen.

If you use GIMP on a Unix-like operating system with the X Window System, you can also drag and drop the thumbnail to an enabled XDS file manager to directly save the corresponding image.

1.4. Tool Options

Pav. 14.6. Tool Options Dialog

Tool Options Dialog

The Tool Options dialog of the Airbrush tool.

Jeigu jūsų programos GIMP sąranka yra panaši į daugelio žmonių, aktyvavus įrankį jo dialogas Įrankio parinktys atsiranda po Įrankine. Jeigu jūsų nustatymai kitokie, greičiausiai turėtumėte juos pakeisti: yra labai sunku naudoti įrankius efektyviai, neturint galimybės keisti jų parinkčių.

The Tool Options appear beneath the Toolbox in the default setup. If you lose it somehow, you can get it back by creating a new Tool Options dialog using WindowsDockable DialogsTool Options and then docking it below the Toolbox. See the section on Dialogs and Docking if you need help.

Each tool has its own specific set of options. The choices you make for them are kept throughout the session, until you change them. In fact, the tool options are maintained from session to session. The persistence of tool options across sessions can sometimes be an annoying nuisance: a tool behaves very strangely, and you can't figure out why until you remember that you were using some unusual option the last time you worked with it, two weeks ago.

At the bottom of the Tool Options dialog, four buttons appear:

Save Tool Preset…

This button allows you to save the settings for the current tool, so that you can restore them later. It brings up the Skyrius 7.1, „Tool Presets Dialog“ allowing you to give a name for the new preset. When you Restore options, only saved presets for the active tool are shown, so you need not worry about including the name of the tool when you assign a name here.

Restore Tool Preset…

This button allows you to restore a previously saved preset of options for the active tool. If no presets have ever been saved for the active tool, the button will be disabled. Otherwise, clicking it will bring up a menu showing the names of all saved option sets: choosing a menu entry will apply those settings.

Delete Tool Preset

This button allows you to delete a previously saved set of options for the active tool. If no option-sets have ever been saved for the active tool, the button will simply repeat the tool name. Otherwise, clicking it will bring up a menu showing the names of all saved presets: the selected preset will be deleted.

Reset to default values

This button resets the options for the active tool to their default values. If you hold the Shift key while pressing the Reset button, the options for all tools will be reset to their default values.

In addition to the commands for the above buttons, the Tool Options tab menu has an extra submenu:

Edit Tool Preset

This submenu shows a list of presets for the active tool that you can edit. Selecting one of them will open the Tool Presets Editor with that tool preset loaded. From there you can edit the preset, unless it is one of the default presets that come with GIMP.

Below we will explain the interaction with sliders and the mouse scroll-wheel.

New sliders

Option sliders have changed with GIMP-2.10.18: Sliders typically used in GEGL-based filters and tools’ options now have a compact style by default: they take a lot less space vertically and have a vastly improved behavior. You can use multiple modifiers with either left-click or mouse wheel scrolling:

Lentelė 14.1. Interaction with the Slider Widget

Mouse / key combination



Change the value to what's under the pointer


Change the value using the default increment

Shift + Left-click-and-drag or Right-click-and-drag

Change the value using smaller increment

Ctrl + Left-click-and-drag

Change the value using larger increment


Enter numeric input mode, do not select the value


Enter numeric input mode, select the value
Hint: Any left-click interaction enables numeric input mode.

Once you have set the value approximately, you can tune it precisely using the two small arrow buttons at the right of the slider.

The value area in the slider area works as a text editor: there, you can edit the value or enter a new value directly.

For some options, you can drag the pointer outside the tool dialog. For example with the size slider, you can get the maximum value (10000) so.

Mouse Scroll-Wheel actions on canvas

When using tools, you can use the mouse scroll-wheel, in combination with various modifiers, to do useful things with the tool options of the selected tool:

  • Alt + Mouse-wheel:  increase/decrease opacity

  • Shift+Primary + Mouse-wheel:  increase/decrease aspect ratio

  • Shift+Alt + Mouse-wheel:  increase/decrease angle

  • Primary+Alt + Mouse-wheel:  increase/decrease size

  • Shift+Primary+Alt + Mouse-wheel:  increase/decrease spacing

Note: the Primary modifier is usually Ctrl or Cmd, depending on your platform.
