3.4.4. Scale Tool

The Scale Tool is used to scale images or layers.

Activate Tool
  • The Scale Tool can be called in the following order, from the image-menu: Tools/ Transform Tools/Scale .

  • The Tool can also be called by clicking the tool icon:

Key modifiers (Defaults)

The Shift-t key combination will change the active tool to Scale.


Holding Ctrl will constrain the scale height.


Holding Alt will constrain the scalewidth.



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


The scale can affect the Layer, the Selection, and the Path differently. These three buttons associate the remainder of the options to one of those three elements.

Transform Direction

The Transform Direction sets which way or direction a layeris rotated. The Traditional mode will rotate the layer as one might expect. If a layer is rotated 10 degrees to the right, then the layer will be rendered as such. This behaviour is contrary to Corrective rotation.

Corrective Scaling is primarily used to repair scanned images that are not straight. If the image is 13 degrees askew then you need not try to rotate by that angle. By using Corrective Skalierung you can rotate visually and line up the layer with the image. Because the transformation is reversed, or performed backwards, the image will be rotated with sufficient angle to correct the error.


The Interpolation drop-down list allows you to choose the quality of the transformation. For more information about the different methods that can be employed, see the glossary entry Interpolation.

Clip Result

This option will clip the rotated layer to the original layer size.

Grid Options

The three available grid options are used to change thevisual display of the rotation grid.

Don't Show Grid will display only the outline of the rotation rectangle.

Number of Grid Lines will allow control over the total number of displayed grid lines. Use the Density slider to set the number of grid lines.

Grid Line Spacing allows control overthe distance between the grid lines. Use the Density slider to set the distance.


Keep Height will constrain the scale such that the height of the layer will remain constant.

Keep Width will constrain the scale such that the width of the layer will remain constant.
