4.3. Rotate Tool

The wilber opened in the RGBA mode. The Rotate Tool is used to rotate layers.

Activate Tool

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

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

Key modifiers (Defaults)

Shortcut

The Shift-r key combination will change the active tool to Rotate.

Ctrl

Holding Ctrl will constrain the rotation angles to those only evenly divisible by 15 degrees.

Options

Overview

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

Affect

The Rotate tool 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 layer is 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 Rotation 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 Rotation 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.

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.

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 the visual 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 over the distance between the grid lines. Use the Density slider to set the distance.

Constraints

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