[Mapnik-users] pan and zoom

[Hank Sims]

    Hi there,

    Total n00b here, and I apologize if this question is answered
elsewhere on the web. I searched and searched, but I couldn't find it.
    So I know what a Map object's zoom_to_box method does, and I know
what m.zoom_all() does, but I can't figure out what these methods do,
even after playing around with them for a bit:

     * m.zoom()
     * m.pan()
     * m.pan_and_zoom()

     Any quick answers? Thanks in advance...
