class CropData:
"""Crop data class.

This class is used to crop data based on a specified bounding box.

Args:
xmin (Tuple[int, ...]): Bottom left corner point, [x0, y0].
xmax (Tuple[int, ...]): Top right corner point, [x1, y1].
apply_keys (Tuple[str, ...], optional): Which data is the crop method applied to. Defaults to ("input", "label").

Examples:
>>> import ppsci
>>> import numpy as np
>>> crop_data = ppsci.data.transform.CropData((0, 0), (720, 1440))
>>> input_item = {"input": np.zeros((1, 3, 720, 1440))}
>>> label_item = {"label": np.zeros((1, 3, 720, 1440))}
>>> weight_item = {"weight": np.ones((1, 3, 720, 1440))}
>>> input_item, label_item, weight_item = crop_data(input_item, label_item, weight_item)
