With this method you can rotate images by defined angles. This function was especially developed for rotating complex (multi-dimensional) images in the available image dimensions. Therefore, the function can be a little bit slower but offers more settings for the rotation. For simple, 2-dimensional rotations we recommend to use the Rotate 2D function which is usually a lot faster.

Parameter

Description

Third Dimension

Only visible, if there is a third dimension in the input image and/or Show all mode is activated.

Here you can select how you want the function to work in the case of multidimensional images.

-

2D Slices

The function is used in a 2-dimensional fashion only for multidimensional images such as time lapse or z-stacks.

-

Z, T or C

Here you can select to which additional dimension the functions should be applied to.

Adapt Sizes

Activated: The size of the output image is adjusted in accordance with the settings for the scaling.

Deactivated: The output image has the same size as the input image. Depending on the image size and rotation angle, partial areas of the input image may not be visible in the output image.

Adjust per Channel

Only visible if your input image is a multi-channel image.

Activated: You can adjust the parameters for each channel individually.

Interpolation

Here you can select how you want interpolation to be performed if a pixel is calculated from several individual pixels.

-

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.

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.

Angle X

Enter the angle by which you want the input image to be rotated on the X axis using the slider or input field.

Angle Y

Enter the angle by which you want the input image to be rotated on the Y axis using the slider or input field.

Angle Z

Enter the angle by which you want the input image to be rotated on the Z axis using the slider or input field.

The following parameters are only visible if Adapt Sizes is deactivated:

Center X

Enter the X coordinate of the center of the rotation using the slider or spin box/input field.

The value 0 means that the image is rotated around its center point. Negative values mean that the center of the rotation in the image is shifted to the left in relation to the image's center point. Positive values shift the center to the right.

Center Y

Enter the Y coordinate of the center of the rotation using the slider or spin box/input field.

The value 0 means that the image is rotated around its center point. Negative values mean that the center of the rotation in the image is shifted downwards in relation to the image's center point. Positive values shift the center upwards.

Center Z

Enter the Z coordinate of the center of the rotation using the slider or spin box/input field.

The value 0 means that the image is rotated around its center point. Negative values mean that the center of the rotation in the image is shifted forwards in relation to the image's center point. Positive values shift the center backwards.
