        Save an image with the transfer function represented as a colorbar.

        Parameters
        ----------
        fn : str
           The output filename
        image : ImageArray
           The image to annotate
        enhance : bool, optional
           Enhance the contrast (default: True)
        dpi : int, optional
           Dots per inch in the output image (default: 100)
        clear_fig : bool, optional
           Reset the figure (through pylab.clf()) before drawing.  Setting 
           this to false can allow us to overlay the image onto an 
           existing figure
        label_fmt : str, optional
           A format specifier (e.g., label_fmt="%.2g") to use in formatting 
           the data values that label the transfer function colorbar.
