4.5. Rotate

4.5.1. Overview

This tool is used to rotate the active layer, a selection or a path. When you click on the image or the selection with this tool a Rotation adjustment dialog is opened. There, you can set the rotation axis, marked with a point, and the rotation angle. You can do the same by dragging the mouse pointer on the image or the rotation point.

4.5.2. Activating the Tool

There are different possibilities to activate the tool:

  • From the main menu: ToolsTransform ToolsRotate.

  • By clicking the tool icon in the Toolbox.

  • By pressing the Shift+R keyboard shortcut.

4.5.3. Key modifiers (Defaults)


Holding Ctrl will constrain the rotation angle to 15 degrees increments.

Rotation tool options

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 WindowsDockable WindowsTool Options which opens the option window of the selected tool.

Transform; Direction, Interpolation; Clipping; Show image preview; Guides
[Poznámka] Poznámka

These options are described in Transform tools common options.

Směr transformace

The Transform Direction sets which way or direction a layer is rotated. The Normal 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 behavior is contrary to Corrective rotation.

Zpět (Korektivní) nastavuje opačné chování. Slouží především k opravě skenovaných obrázků, které nebyly na skener položeny rovně.

15 Degrees (Shift)

15 Degrees (Shift) will constrain the rotation to angles divisible by 15 degrees.

Here you can set the rotation angle, from -180° to +180°, i.e. 360°.

Center X/Y

This option allows you to set the position of the rotation center, represented by a cross surrounded by a circle in the image. A click-and-drag on this point also allows you to move this center even outside the image. Default unit of measurement is pixel, but you can change it by using the drop-down list.

Readjust button

With this button, available since GIMP 2.10.10, 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.

[Poznámka] Poznámka

You can also rotate layers with LayerTransformArbitrary Rotation…. See 7.49 – „Arbitrary Rotation“.
