The shortest edge of the image is resized to size["shortest_edge"] , with the longest edge resized to keep the input aspect ratio. Both the height and width are resized to be divisible by 32. Args: image (`np.ndarray`): Image to resize. size (`Dict[str, int]`): Size of the output image. size_divisor (`int`, *optional*, defaults to `32`): Ensures height and width are rounded to a multiple of this value after resizing. resample (`PILImageResampling`, *optional*, defaults to `PILImageResampling.BILINEAR`): Resampling filter to use when resiizing the image. data_format (`str` or `ChannelDimension`, *optional*): The channel dimension format of the image. If not provided, it will be the same as the input image. input_data_format (`ChannelDimension` or `str`, *optional*): The channel dimension format of the input image. If not provided, it will be inferred. default_to_square (`bool`, *optional*, defaults to `False`): The value to be passed to `get_size_dict` as `default_to_square` when computing the image size. If the `size` argument in `get_size_dict` is an `int`, it determines whether to default to a square image or not.Note that this attribute is not used in computing `crop_size` via calling `get_size_dict`. r-r0r1zASize must contain either 'shortest_edge' or 'height' and 'width'.F)r!r6r.r)r!r#r5r6) ValueErrorr r"r ) r;r@r!r#r5r6r<r0r1r7r7r?r s,  zTextNetImageProcessor.resizer3r4c s|dur|n|j}|dur|n|j}t|ddd}|dur|n|j}|dur(|n|j}|dur1|n|j}|dur:|n|j}t|ddd}|durJ|n|j}| durS| n|j} | dur\| n|j } | dure| n|j } | durn| n|j } | durw| n|j } t ||jdt|}t|stdt|| | | | |||||d | rd d |D}d d |D}t|d r|rtddurt|d g}|D]1}|r|j|||d}|r|j||d}|r|j|| d}| r|j|| | d}||qȇfdd |D}d|i}t||dS)a Preprocess an image or batch of images.
