        **Splits an image along a specific axis (e.g., channels).**

        This tool splits an image along a specifc axis and yields a collection of images.
        This can be used, for example, to convert a multi-channel image into a collection of single-channel images.

        The pixel data type of the split image is preserved (will be the same as the input image).
