In many cases it will also be fine to only support contiguous arrays, and make a copy first when getting non-contiguous arrays (possibly in Python code, before passing it to a function in an extension module). This is a common patterns when using Pythran. The end result is usually better...

Thepyautoguimodule provides us with thescreenshot()function with the help of which we can take a screenshot. Thescreenshot()function, when executed, returns a PIL(python image library) file in RGB format. First, we will convert the PIL file into a numpy array using thenumpy.array()...
