unsigned int OEMakeConnectedSurfaceCliques(OESurface &surf)
Assigns a different clique value, starting at 1, to each connected component of the surface. The number of connected components is returned. Listing 2 demonstrates cropping a surface to its largest component.
Listing 2: Extracting the largest portion of the surface
nclqs = OEMakeConnectedSurfaceCliques(surf) areas =  for i in range(1, nclqs+1): areas.append((OESurfaceCliqueArea(surf, i), i)) maxarea, maxclq = max(areas) OESurfaceCropToClique(surf, maxclq)
