Welcome to Python-flavored Magnum! Please note that, while already being rather stable, this functionality is still considered experimental and some APIs might get changed without preserving full backwards compatibility.

corrade.containers.StridedArrayView2D class

Two-dimensional array view with stride information

See StridedArrayView1D for more information.

Methods

def broadcasted(self, dimension: int, size: int) -> StridedArrayView2D: Broadcast a dimension
def expanded(self, dimension: int, size: tuple[int, int]) -> StridedArrayView3D: Expand a dimension
def expanded(self, dimension: int, size: tuple[int, int, int]) -> StridedArrayView4D: Expand a dimension
def flipped(self, dimension: int) -> StridedArrayView2D: Flip a dimension
def slice_bit(self, index: int) -> StridedBitArrayView2D: Slice to a bit
def transposed(self, a: int, b: int) -> StridedArrayView2D: Transpose two dimensions

Special methods

def __buffer__(self, flags, /): Return a buffer object that exposes the underlying memory of the object.
def __bytes__(self, /) -> bytes: Convert to bytes
def __getitem__(self, slice: slice) -> StridedArrayView2D: Slice the view
def __getitem__(self, i: int) -> StridedArrayView1D: Sub-view at given position
def __getitem__(self, i: tuple[int, int]) -> object: Value at given position
def __getitem__(self, slice: tuple[slice, slice]) -> StridedArrayView2D: Slice the view
def __init__(self, /) -> None: Default constructor
def __init__(self, arg0: Buffer, /) -> None: Construct from a buffer
def __len__(self, /) -> int: View size in the top-level dimension
def __release_buffer__(self, buffer, /): Release the buffer object that exposes the underlying memory of the object.

Properties

dimensions: int get: Dimension count
format: str get: Format of each item
owner: object get: Memory owner object
size: tuple[int, int] get: View size in each dimension
stride: tuple[int, int] get: View stride in each dimension

Method documentation

def corrade.containers.StridedArrayView2D.broadcasted(self, dimension: int, size: int) -> StridedArrayView2D

Broadcast a dimension

Exceptions
IndexError	If `dimension` is not `0` or `1`

def corrade.containers.StridedArrayView2D.expanded(self, dimension: int, size: tuple[int, int]) -> StridedArrayView3D

Expand a dimension

Exceptions
IndexError	If `dimension` is not `0` or `1`
ValueError	If product of `size` is not equal to size in `dimension`

def corrade.containers.StridedArrayView2D.expanded(self, dimension: int, size: tuple[int, int, int]) -> StridedArrayView4D

Expand a dimension

Exceptions
IndexError	If `dimension` is not `0` or `1`
ValueError	If product of `size` is not equal to size in `dimension`

def corrade.containers.StridedArrayView2D.flipped(self, dimension: int) -> StridedArrayView2D

Exceptions
IndexError	If `dimension` is not `0` or `1`

def corrade.containers.StridedArrayView2D.transposed(self, a: int, b: int) -> StridedArrayView2D

Transpose two dimensions

Exceptions
IndexError	If `a` or `b` is not `0` or `1` or if they’re the same

def corrade.containers.StridedArrayView2D.getitem(self, i: tuple[int, int]) -> object

Value at given position

Exceptions
IndexError	If `i` is out of range
NotImplementedError	If the view was created from a buffer and format is not one of `'b'`, `'B'`, `'h'`, `'H'`, `'i'`, `'I'`, `'q'`, `'Q'`, `'f'` or `'d'`
