I don't know 1 byte Memory Leaks. help me.

	v_Temp_Poly->GetPointIds()->SetId(k, k);
}

v_Temp_linegrid->SetPoints(v_Temp_points);

m_vtkpModification_Actor->SetMapper(v_Temp_linemapper);

m_pvtkImageViewer->GetRenderer()->AddActor(m_vtkpModification_Actor);
m_pvtkImageViewer->Render();

All VTK objects are created with smart pointers.
1 Byte memory leak occurs.

Do you have a backtrace for the leak? Filters themselves can leak internally.
