What does align_img do in test.py?

[justin4ai]

Hello, I'd like to ask one question about the role of align_img method in util/preprocess.py. Actually I want to remove that method from my code since landmarks argument it takes is from get_landmarks method and its runtime is too long.

Can I get any clue about this? Thank you for your answers in advance!

Seemingly the output is only resized, not aligned.
