// .NAME vtkSMViewExportHelper - helper class to export views.
// .SECTION Description
// vtkSMViewExportHelper is a helper class to aid in exporting views. You can
// create instances of this helper on-demand to query available exporters and
// create and exporter proxy (in same spirit as vtkSMWriterFactory, except that
// there's no globally existing instance).

  // Description:
  // Returns a formatted string with all supported file types for the given
  // view.
  // An example returned string would look like:
  // \verbatim
  // "PVD Files (*.pvd);;VTK Files (*.vtk)"
  // \endverbatim

  // Description:
  // Exports the view to the given output file. Returns a new exporter instance
  // (or NULL). Caller must release the returned object explicitly.
