The Scale Tool can be used to scale a layer, selection, path or image, depending on the Transform setting.
    When you click on your image with the Scale tool,
    the Scale dialog is opened, allowing to change the
    Width and Height. When the
    
      
    
    chain icon is closed, adjustments to one, will adjust the other value
    the same percentage. If you do not want this, click the chain icon to
    disable the synchronization.
    The default size is in pixels, which can be changed in the measurement
    drop-down list besides the chain icon.
  
At the same time a Preview (unless disabled in the Tool Options) is superimposed on the object and handles appear on the corners and borders that you can click and drag to change the dimensions. At the center, a square with a cross inside can be used to move the preview.
Ci sono diverse possibilità per attivare lo strumento:
From the main menu: → → .
          By clicking the tool icon
          
            
          
          in the Toolbox.
        
By pressing the Shift+S keyboard shortcut.
Mantenendo premuto il tasto Maiusc si commuterà l'opzione mantieni l'aspetto.
Mantenendo premuto il tasto Ctrl si commuterà l'opzione Attorno al centro.
Normally, tool options are displayed in a window attached under the Toolbox as soon as you activate a tool. If they are not, you can access them from the main menu through → → which opens the option window of the selected tool. The available tool options can also be accessed by double clicking the corresponding tool icon in the Toolbox.

Per scalare un tracciato, fare riferimento a Trasformazione tracciati.
            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.
          
Quando questa opzione è abilitata, si può scalare dal centro, radialmente se «Mantieni l'aspetto» è selezionata, altrimenti verticalmente o orizzontalmente.
            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.
          
With this button you can reset the transform handles back to the original square shape, while keeping the current transformation and zoom level. This enables you to create more complex transformations by making the transformation in several steps.
