Why can't you simply select, copy and paste it from the silk layer to 
the outline layer?

             Hey folks.  I'm designing a board that needs to have a very
          complex <br>
          outline.  Starting from an image file, I've gotten what I need
          into the <br>

          shape that's <br>

          entire shape, <br>
          for the outline.<br>
          <br>
             Can anyone suggest an automated way to do this?  I'd just
