[vtkusers] creating a vtkPolyDataReader object from a string representation of a vtkPolyDataWriter

Mon Aug 15 14:50:33 EDT 2016

I am trying to convert the char * returned by
vtkPolyDataWriter::GetOutputString() as follows

polyDataString is a char * that points to a valid string from
vtkPolyDataWriter::GetOutputString() .

  vtkSmartPointer<vtkPolyDataReader> transportedDataSetReader =
vtkSmartPointer<vtkPolyDataReader>::New();
  transportedDataSetReader->DebugOn();
  transportedDataSetReader->ReadFromInputStringOn();
  transportedDataSetReader->SetInputString(polyDataString);
  transportedDataSetReader->Update();

*** Update seems to fail with the following debug output.

Generic Warning: In
/builddir/build/BUILD/VTK-6.1.0/IO/Legacy/vtkDataReader.cxx, line 1388
Error reading ascii data. Possible mismatch of datasize with declaration.
