contouring from an explicit point in an array [message #34711]

Hi all,

Is there a way to get only the contour of an image that passes through a
given point? I'm currently doing this by contouring the entire image
using the intensity of the desired point as a level, and then only keeping
the contour with a vertex within half a pixel of that point. But this
seems pretty kludgey and error-prone to me.
