    Constructs a Donut processor which wraps a Donut image processor and an XLMRoBERTa tokenizer into a single
    processor.

    [`DonutProcessor`] offers all the functionalities of [`DonutImageProcessor`] and
    [`XLMRobertaTokenizer`/`XLMRobertaTokenizerFast`]. See the [`~DonutProcessor.__call__`] and
    [`~DonutProcessor.decode`] for more information.

    Args:
        image_processor ([`DonutImageProcessor`], *optional*):
            An instance of [`DonutImageProcessor`]. The image processor is a required input.
        tokenizer ([`XLMRobertaTokenizer`/`XLMRobertaTokenizerFast`], *optional*):
            An instance of [`XLMRobertaTokenizer`/`XLMRobertaTokenizerFast`]. The tokenizer is a required input.

        When used in normal mode, this method forwards all its arguments to AutoImageProcessor's
        [`~AutoImageProcessor.__call__`] and returns its output. If used in the context
        [`~DonutProcessor.as_target_processor`] this method forwards all its arguments to DonutTokenizer's
        [`~DonutTokenizer.__call__`]. Please refer to the doctsring of the above two methods for more information.

        Temporarily sets the tokenizer for processing the input. Useful for encoding the labels when fine-tuning TrOCR.
        z`as_target_processor` is deprecated and will be removed in v5 of Transformers.
