부 III. GIMP 기능 설명 | |
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.)

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 five 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 distribution of colors across the entire image;
Other tools, which don't fall into the other four categories.
Most tools can be activated by clicking on an icon in the Toolbox. By default, some tools are accessible only via the menus (namely the Color tools are accessible only either as or as → ). Every tool, in fact, can be activated from the Tools menu; also, every tool can 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: the Color tools are omitted. You can customize the set of tools that are shown in the Toolbox through → → . 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 the Color tools a lot, you might find it convenient to have icons for them easily available. In any case, regardless of the Toolbox, you can always access any tool at any time using the menu from an image menubar.
The shape of the cursor changes when it is inside an image, to one that indicates which tool is active (if in you have set → → → ).
This area shows GIMP's basic palette, consisting of two colors, the Foreground and Background, used for painting, filling, and many other operations. Clicking on either of the color displays brings up a Color Editor dialog, which permits you to change it.
Clicking on this small symbol resets the Foreground and Background colors to black and white, respectively. Pressing the D key has the same effect.
Clicking on the small curved line with two arrowheads causes the Foreground and Background colors to be swapped. Pressing the X key has the same effect.

You can click-and-drag one of these colors directly into a layer: it will fill the whole layer. |
This part of the Toolbox shows the currently selected brush, pattern, and gradient. Clicking on any of them brings up a dialog that allows you to change it.
A thumbnail of the active image can be displayed in this area if the “Display Active Image” option is checked in Preferences/Toolbox. If you click on this thumbnail, the “Images” dialog is opened, useful if you have many images on your screen. You can also click and drag this thumbnail to an enabled XDS[9] file manager to directly save the corresponding image.

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 → → 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:
선택사항 저장...
This button allows you to save the settings for the current tool, so that you can restore them later. It brings up the 5.1절. “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.
선택사항 복원...
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 insensitive. Otherwise, clicking it will bring up a menu showing the names of all saved option sets: choosing a menu entry will apply those settings.
저장된 설정사항 지우기...
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.

Option sliders have changed with GIMP-2.8: it is not visible, but the slider area is now divided into upper and lower parts.
그림 14.7. The new sliders of tool options dialogs
The upwards arrow pointer in the top half of the slider area
The horizontal two-way arrow pointer in the lower half of the slider area
In the top half of the slider area: Clicking with the up arrow pointer sets slider to a value that depends on the position of the pointer (no reference, imprecise). Clicking and dragging the up arrow pointer sets the value by large amounts.
In the lower half of the slider area: Clicking with the two-way arrow pointer has no effect. Clicking and dragging the two-way arrow pointer sets the value by small amounts.
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, whose maximum value is 10,000, you can drag the mouse pointer up to the right side of your screen.
