return a subgraph of a <a class="el" href="a00654.html" title="Base class for graph data types.">vtkGraph</a>
<p>
The first input is a <a class="el" href="a00654.html" title="Base class for graph data types.">vtkGraph</a> to take a subgraph from. The second input is a <a class="el" href="a01522.html" title="A node in a selection tree. Used to store selection results.">vtkSelection</a> containing the selected indices. The <a class="el" href="a01522.html" title="A node in a selection tree. Used to store selection results.">vtkSelection</a> may have FIELD_TYPE set to POINTS (a vertex selection) or CELLS (an edge selection). A vertex selection preserves all edges that connect selected vertices. An edge selection preserves all vertices that are adjacent to at least one selected edge. Alternately, you may indicate that an edge selection should maintain the full set of vertices, by turning RemoveIsolatedVertices off.<p>
