We will use np.arrays to represent images, and matplotlib to display images. We can do this with no additional packages required. However, two common packages for working with images are imageio and ...

In this example, we use the NumPy array’s .shape attribute to obtain its dimensions. We then use range() to iterate through the memoryview with those dimensions as a constraint.

Here’s a simple example: import numpy as np np.array ... Using NumPy arrays with C libraries: A common use case for Cython is to write convenient Python wrappers for C libraries.
