4.5.1.  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 with a grid or an outline is superimposed on the object and handles appear on corners that you can click and drag to change these dimensions. A small circle appears at center of the Preview allowing to move this preview.
