Contour interpolator for placing points on an image.
vtkDijkstraImageContourLineInterpolator interpolates and places contour points on images. The class interpolates nodes by computing a graph lying on the image data. By graph, we mean that the line interpolating the two end points traverses along pixels so as to form a shortest path. A Dijkstra algorithm is used to compute the path.
The class is meant to be used in conjunction with vtkImageActorPointPlacer. One reason for this coupling is a performance issue: both classes need to perform a cell pick, and coupling avoids multiple cell picks (cell picks are slow). Another issue is that the interpolator may need to set the image input to its vtkDijkstraImageGeodesicPath ivar.
