_generate_grid_slice(shape, *, offset, stride=3)

Parameters

shape : tuple of int

Shape of the mask.

offset : int

The offset of the grid of ones. Iterating over offset will cover the entire array. It should be between 0 and stride ** ndim , not inclusive, where ndim = len(shape) .

stride : int, optional

The spacing between ones, used in each dimension.

Returns

mask : ndarray

The mask.

Generate slices of uniformly-spaced points in an array.

Examples

This example is valid syntax, but we were not able to check execution
>>> shape = (4, 4)
... array = np.zeros(shape, dtype=int)
... grid_slice = _generate_grid_slice(shape, offset=0, stride=2)
... array[grid_slice] = 1
... print(array) [[1 0 1 0] [0 0 0 0] [1 0 1 0] [0 0 0 0]]

Changing the offset moves the location of the 1s:

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
