- scipy.ndimage.rotate(input, angle, axes=(1, 0), reshape=True, output=None, order=3, 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.
input : ndarray
The input array.
angle : float
The rotation angle in degrees.
axes : tuple of 2 ints, optional
The two axes that define the plane of rotation. Default is the first two axes.
reshape : bool, optional
If reshape is true, the output shape is adapted so that the input array is contained completely in the output. Default is True.
output : ndarray or dtype, optional
The array in which to place the output, or the dtype of the returned array.
order : int, optional
The order of the spline interpolation, default is 3. The order has to be in the range 0-5.
mode : str, optional
Points outside the boundaries of the input are filled according to the given mode (‘constant’, ‘nearest’, ‘reflect’ or ‘wrap’). Default is ‘constant’.
cval : scalar, optional
Value used for points outside the boundaries of the input if mode='constant'. Default is 0.0
prefilter : bool, optional
The parameter prefilter determines if the input is pre-filtered with spline_filter before interpolation (necessary for spline interpolation of order > 1). If False, it is assumed that the input is already filtered. Default is True.
rotate : ndarray or None
The rotated input. If output is given as a parameter, None is returned.
