        patch_size (`int`, *optional*, defaults to 28):
            The size of image patches for tokenization.
        pixel_shuffle_ratio (`float`, *optional*, defaults to `0.5`):
            The ratio used for pixel shuffling when processing images. This controls the downsampling factor
            applied to image patches. The actual downsampling ratio is calculated as `1 / (pixel_shuffle_ratio^2)`.
        fake_image_token (`str`, *optional*, defaults to `"<|image|>"`):
            The placeholder token in the text that will be replaced with actual image tokens. This token serves
            as a marker indicating where images should be inserted in the text sequence.
        image_token (`str`, *optional*, defaults to `"<|image|>"`):
            The token to be used to represent an image in the text.
        start_of_image_token (`str`, *optional*, defaults to `"<|image_start|>"`):
            The special token that marks the beginning of an image sequence in the text. This token is prepended
            to image token sequences to delimit image boundaries.
        end_of_image_token (`str`, *optional*, defaults to `"<|image_end|>"`):
            The special token that marks the end of an image sequence in the text. This token is appended to
            image token sequences to delimit image boundaries.
        patch_token (`str`, *optional*, defaults to `"<|patch|>"`):
            The token used to represent individual image patches. Multiple patch tokens are used to represent
            the full image, with the number depending on the image size and patch configuration.
        tile_x_separator_token (`str`, *optional*, defaults to `"<|tile_x_separator|>"`):
            The token used to separate tiles (patches) horizontally within an image. This token is inserted
            between patches in the same row when images are split into multiple tiles.
        tile_y_separator_token (`str`, *optional*, defaults to `"<|tile_y_separator|>"`):
            The token used to separate tiles (patches) vertically within an image. This token is inserted
            between rows of patches when images are split into multiple tiles.
