vectorlike representation of isocontours

Hello everybody,

is there a way of getting a vectorlike representation of one/all painted isocontours in an image/dataset. This vectorlike representation should handle like java.awt.geom.GeneralPath or a java.util.Vector.

My problem is similar to:
Get the outline of the 500m topography in a Linear2DSet (this is visads work) and shrink it by 150 m in the horizontal direction towards the ballance point (my own calculation).

It is possible, that other calculations for the points of the vectorlike representation may follow.

Thanks for your answers.
