The Scale tool in Toolbox

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.  Activate the Tool

  • You can access the Scale tool from the image-menu through: ToolsTransform ToolsScale,

  • or by clicking the tool icon: in the Toolbox,

  • or by using the Shift+T key combination.

The available tool options for the Scale Tool can be accessed by double clicking the Scale Tool icon in Toolbox.

Transform; Interpolation; Direction; Clipping; Preview
[Note] Note

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

[Note] Note

These options are described in Transform tools common options.

Keep Aspect

Keep Aspect: 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.

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.
