We want to perform augmentation on the image label. Therefore, it requires the nearest interpolation. We wonder whether there is the IO for this operation.

Yes there is! You can assign an interpolation order to an Interpolator object, for example order=0 for nearest neighbor interpolation. For example, given image (some_image of type np.ndarray) and a Gryds transformation object some_transformation:

interpolator = gryds.Interpolator(some_image, order=0)
transformed_image = interpolator.transform(some_transformation)
