4.4. Scale Tool

The Scale Tool is used to scale images, selections or layers (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 grid covers 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 object allowing to move this object.

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)

Shortcut

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

Ctrl

Holding Ctrl will constrain the scale height.

Alt

Holding Alt will constrain the scalewidth. If Alt doesn't work, try Shift+Alt.

Options

Overview

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

Affect

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

Forward (Traditional): The Traditional mode will scale the layer as one might expect. If a layer is scaled to the right, then the layer will be rendered as such: with an enlarged grid, layer will be rendered enlarged.

Backward (Corrective): Performs transformation in the reverse direction. If a layer is scaled to the right (enlarged), then the layer will be rendered to the left (reduced).

Interpolation

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.

Supersampling

See glossary at Supersampling.

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.

Constraints

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.
