#### 4.6.1. Overview

The Scale Tool is used to scale layers, selections or paths (the Object).

When you click on image with the tool the Scaling Information dialog box is opened, allowing to change separately Width and Height. At the same time a Preview (possibly with a grid or an outline) is superimposed on the object and handles appear on corners and borders that you can click and drag to change dimensions. A small circle appears at center of the Preview allowing to move this preview.

#### 4.6.2. Activating the Tool

You can access the Scale Tool in different ways:

- from the image menu bar Tools → Transform Tools → Scale,

- by clicking the tool icon: in the Toolbox,

- by using the Shift+T key combination.

#### 4.6.3. Key modifiers (Defaults)

Ctrl

  Holding the Ctrl key down will toggle the Keep Aspect option.

#### 4.6.4. Tool Options

Figura 14.124. Tool options for the Scale tool

Normalmente, as opções da ferramenta são exibidas assim que você ativa uma ferramenta em uma caixa localizada abaixo da caixa de ferramentas. Se isso não acontecer, você pode acessar as mesmas através do menu na janela da imagem emJanelas → Diálogos de Encaixe → Opções de ferramentas

Transform; Interpolation; Direction; Clipping; Preview; Guides

  | Nota
  These options are described in Transform tools common options.

  | Nota
  The Transform mode works on the active layer only. To work on all layers of the image, use Scale Image.

Keep Aspect (Ctrl)

  When you move a corner of the selection frame, this option will constrain the scale such as the Height/Width ratio of the layer will remain constant. Note that this doesn't work with border handles. Note also that it toggles the linking chain in the dialog.

Width/Height

  Here, you can set Width and Height you want to give to the object. The default unit of measurement is pixel. You can change it by using the drop-down list. These values are also automatically changed when you drag handles in the image. If the associated linking chain is broken, you can change Width and Height separately.
