create_coordinate_arrays#

orix.crystal_map.create_coordinate_arrays(shape: Optional[tuple] = None, step_sizes: Optional[tuple] = None) → Tuple[dict, int][source]#

Create flattened coordinate arrays from a given map shape and step sizes, suitable for initializing a CrystalMap. Arrays for 1D or 2D maps can be returned.

Parameters:

shape: Map shape. Default is a 2D map of shape (5, 10) with five rows and ten columns.
step_sizes: Map step sizes. If not given, it is set to 1 px in each map direction given by shape.

Returns:

d: Dictionary with keys "y" and "x", depending on the length of shape, with coordinate arrays.
map_size: Number of map points.

Examples

>>> from orix.crystal_map import create_coordinate_arrays
>>> create_coordinate_arrays((2, 3))
({'x': array([0, 1, 2, 0, 1, 2]), 'y': array([0, 0, 0, 1, 1, 1])}, 6)
>>> create_coordinate_arrays((3, 2))
({'x': array([0, 1, 0, 1, 0, 1]), 'y': array([0, 0, 1, 1, 2, 2])}, 6)
>>> create_coordinate_arrays((2, 3), (1.5, 1.5))
({'x': array([0. , 1.5, 3. , 0. , 1.5, 3. ]), 'y': array([0. , 0. , 0. , 1.5, 1.5, 1.5])}, 6)
