        In the case of NumPy, be aware that Pillow modes do not always correspond
        to NumPy dtypes. Pillow modes only offer 1-bit pixels, 8-bit pixels,
        32-bit signed integer pixels, and 32-bit floating point pixels.

        Pillow images can also be converted to arrays::

          from PIL import Image
          import numpy as np
          im = Image.open("hopper.jpg")
          a = np.asarray(im)

        When converting Pillow images to arrays however, only pixel values are
        transferred. This means that P and PA mode images will lose their palette.

        :param obj: Object with array interface
        :param mode: Optional mode to use when reading ``obj``. Since pixel values do not
          contain information about palettes or color spaces, this can be used to place
          grayscale L mode data within a P mode image, or read RGB data as YCbCr for
          example.
