9.1. Getprojection

Use the Image.getprojection() method to return two sequences, indicating where there are non-zero pixels (with a 1) along the X-axis and the Y-axis, respectively.

from PIL import Image

with Image.open("shapes/box.png") as im:
    print(im.getprojection())
    # ([1, 1, 1,....], [1, 1, 1,  ...])
