The method uses texture memory and supports only 2D and 3D float32 arrays without channel dimension. Args: data (cupy.ndarray): The input array or texture object. transformation_matrix (cupy.ndarray): Affine transformation matrix. Must be a homogeneous and have shape ``(ndim + 1, ndim + 1)``. output_shape (tuple of ints): Shape of output. If not specified, the input array shape is used. Default is None. output (cupy.ndarray or ~cupy.dtype): The array in which to place the output, or the dtype of the returned array. If not specified, creates the output array with shape of ``output_shape``. Default is None. interpolation (str): Specifies interpolation mode: ``'linear'`` or ``'nearest'``. Default is ``'linear'``. mode (str): Specifies addressing mode for points outside of the array: (`'constant'``, ``'nearest'``). Default is ``'constant'``. border_value: Specifies value to be used for coordinates outside of the array for ``'constant'`` mode. Default is 0. Returns: cupy.ndarray: The transformed input. .. seealso:: :func:`cupyx.scipy.ndimage.affine_transform` zdTexture memory affine transformation is defined only for 2D and 3D arrays without channel dimension.zRTexture memory affine transformation is available only for float32 data type (not ))r r zUnsupported interpolation z (supported: linear, nearest)z.Matrix must be have shape (ndim + 1, ndim + 1)r)r/r0r1r2N)rzOutput shapes do not matchz/Output must be None, cupy.ndarray or cupy.dtype) r+rrrfloat32r'r:!_affine_transform_2d_array_kernel!_affine_transform_3d_array_kernelzeros isinstancetypendarray) r.transformation_matrix output_shapeoutput interpolationmode border_valuer+rtexture_objectkernels r9affine_transformationrPrsJ 99D qdQh :; ; JJE  <L<3CLVL Mr;)r)r/strr0rQr1rQ)NNr r r)rKrQrLrQ) __future__rrr cupy.cudarrElementwiseKernelrBrCr:rPr;r9rVs" %*$;$;+-B 3% !*%*$;$;: 3!% !8)* 8),8(+8'*8z(,!%/7&0'( U*- U !$ Ur;
