Contour interpolator for placing points on an image.
<p>
<a class="el" href="a00418.html" title="Contour interpolator for placing points on an image.">vtkDijkstraImageContourLineInterpolator</a> 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.<p>
The class is meant to be used in conjunction with <a class="el" href="a00726.html" title="Converts 2D display positions to world positions such that they lie on an ImageActor...">vtkImageActorPointPlacer</a>. 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 <a class="el" href="a00419.html" title="Dijkstra algorithm to compute the graph geodesic.">vtkDijkstraImageGeodesicPath</a> ivar.<p>
