Edge detection and measuring lengths

Hi All,
       
        Is it possible to use ImageJ to automatically detect edges in an
        image
        and then measure the distance between the two edges?
       
        I have written an image J macro that is called from some c code,
        this
        uses the process->find edges command and then writes the image
        to a text
        image file. But this doesn't really make the code aware of where
        the
        edges are, it just allows me to see them.
       
        Thanks,
       
        Wes.
