apply_transformation#

pyxem.utils.diffraction.apply_transformation(z, transformation, keep_dtype, order=1, *args, **kwargs)[source]#

Apply a transformation to a 2-dimensional array.

Parameters:

z (numpy.ndarray) – Array to be transformed
transformation (numpy.ndarray) – 3x3 numpy array specifying the transformation to be applied.
order (int) – Interpolation order.
keep_dtype (bool) – If True dtype of returned object is that of z
*args – To be passed to skimage.transform.warp()
**kwargs – To be passed to skimage.transform.warp()

Returns:

trans – Affine transformed diffraction pattern.

Return type:

array

Notes

Generally used in combination with pyxem.expt_utils.convert_affine_to_transform()
