pub fn interpolate_nearest<P>(
    img: &impl GenericImageView<Pixel = P>,

) -> Option<P>where
    P: Pixel,Expand description
Sample from an image using coordinates in [0, w-1] and [0, h-1], taking the nearest pixel.
Coordinates outside the image bounds will return None, however the
behavior for points within half a pixel of the image bounds may change in
the future.
