        The call function to the pipeline for generation.

        Args:
            image (`torch.Tensor` or `PIL.Image.Image`):
                The original image to inpaint on.
            mask_image (`torch.Tensor` or `PIL.Image.Image`):
                The mask_image where 0.0 define which part of the original image to inpaint.
            num_inference_steps (`int`, *optional*, defaults to 1000):
                The number of denoising steps. More denoising steps usually lead to a higher quality image at the
                expense of slower inference.
            eta (`float`):
                The weight of the added noise in a diffusion step. Its value is between 0.0 and 1.0; 0.0 corresponds to
                DDIM and 1.0 is the DDPM scheduler.
            jump_length (`int`, *optional*, defaults to 10):
                The number of steps taken forward in time before going backward in time for a single jump ("j" in
                RePaint paper). Take a look at Figure 9 and 10 in the
                [paper](https://huggingface.co/papers/2201.09865).
            jump_n_sample (`int`, *optional*, defaults to 10):
                The number of times to make a forward time jump for a given chosen time sample. Take a look at Figure 9
                and 10 in the [paper](https://huggingface.co/papers/2201.09865).
            generator (`torch.Generator`, *optional*):
                A [`torch.Generator`](https://pytorch.org/docs/stable/generated/torch.Generator.html) to make
                generation deterministic.
            output_type (`str`, `optional`, defaults to `"pil"`):
                The output format of the generated image. Choose between `PIL.Image` or `np.array`.
            return_dict (`bool`, *optional*, defaults to `True`):
                Whether or not to return a [`ImagePipelineOutput`] instead of a plain tuple.
