[vtkusers] Read .vtk file and save as binary STL file

[Swetha Sharma]

Hi kenichiro,

   Thanks for the reply. I have a problem reading the .vtk file .Below is
the code which I had used to read .vtk


vtkSmartPointer<vtkGenericDataObjectReader> reader =
      vtkSmartPointer<vtkGenericDataObjectReader>::New();
  std::cout<<"filename:"<<argv[1]<<"\n";
  reader->SetFileName(argv[1]);


  reader->Update();


 I am getting an error: error reading ascii file.possible mismatch of
datasize with declaration. How do I fix this?
