With this method, you can easily rotate an image clockwise around its center axis. Simply set the desired angle with the slider. Of course, you can enter the angle value in the input field directly. To perform the rotation, click on the Apply button on top of the Processing tab.

Parameter

Description

Angle

Enter the angle by which you want the input image to be rotated around using the slider or input field. Positive angles rotate the images clockwise.

Interpolation

-

Nearest Neighbor

The output pixel is given the gray value of the input pixel that is closest to it.

-

Linear

The output pixel is given the gray value resulting from the linear combination of the input pixels closest to it.

-

Cubic

The output pixel is given the gray value resulting from a polynomial function of the input pixels closest to it.

Edge Smoothing

Activated: Performs edge smoothing.

PaveWholePlane

Activated: Paves the whole resulting plane with tiles; there might be empty tiles.

Inactivated: Creates only tiles which contain also parts of the image.

ProcessMask

Activated: Rotates also the mask of valid/invalid pixels.

Inactivated: Ignores the mask of valid/invalid pixels. Pixels previously marked as invalid will have an intensity of zero after rotation but are not marked as invalid.

IncludeGraphic Elements

Activated: Rotates also the graphical elements together with the image.

Inactivated: Rotates only the image, but not the graphical elements.
