cupyx.scipy.ndimage.rotate

cupyx.scipy.ndimage.rotate(input, angle, axes=(1, 0), reshape=True, output=None, order=None, mode='constant', cval=0.0, prefilter=True)

Rotate an array.

The array is rotated in the plane defined by the two axes given by the axes parameter using spline interpolation of the requested order.

Parameters
  • input (cupy.ndarray) – The input array.

  • angle (float) – The rotation angle in degrees.

  • axes (tuple of 2 ints) – The two axes that define the plane of rotation. Default is the first two axes.

  • reshape (bool) – If reshape is True, the output shape is adapted so that the input array is contained completely in the output. Default is True.

  • output (cupy.ndarray or dtype) – The array in which to place the output, or the dtype of the returned array.

  • order (int) – The order of the spline interpolation. If it is not given, order 1 is used. It is different from scipy.ndimage and can change in the future. Currently it supports only order 0 and 1.

  • mode (str) – Points outside the boundaries of the input are filled according to the given mode ('constant', 'nearest', 'mirror' or 'opencv'). Default is 'constant'.

  • cval (scalar) – Value used for points outside the boundaries of the input if mode='constant' or mode='opencv'. Default is 0.0

  • prefilter (bool) – It is not used yet. It just exists for compatibility with scipy.ndimage.

Returns

The rotated input.

Return type

cupy.ndarray or None
