// .NAME vtkSynchronizedTemplates2D - generate isoline(s) from a structured points set
// .SECTION Description
// vtkSynchronizedTemplates2D is a 2D implementation of the synchronized
// template algorithm. Note that vtkContourFilter will automatically
// use this class when appropriate.

// .SECTION Caveats
// This filter is specialized to 2D images.

// .SECTION See Also
// vtkContourFilter vtkSynchronizedTemplates3D
