Hi all,

I apologize if this has been asked before, but it's currently a little =
difficult to search the archives. Basically what I want to know is, what =
is the best way to represent the points of a closed contour that I've =
traced out on a 2-D, binary image? I am currently just using =
std::vector<itk::Point> for this purpose, but I would like to be able to =
perform operations like "Is a given point inside the contour or =
outside?", and I suspect that there is already something in ITK that =
will let me do this. Thanks in advance.

Best regards,
Parag Chandra
