[vtkusers] VectorText rotating center

[Dejan Zivkovic]

Hi,

I would like to have VectorText that is rotation around its central
vertical axis.

I wrote some code like this:

*vtkSmartPointer<vtkVectorText> m_TextSource =
vtkSmartPointer<vtkVectorText>::New();*
*m_TextSource->SetText("3DIA");*
*m_TextSource->Update();*

*vtkSmartPointer<vtkPolyDataMapper> m_Mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();*
*m_Mapper->SetInputConnection(m_TextSource->GetOutputPort());*

*vtkSmartPointer<vtkActor> **m_Actor = vtkSmartPointer<vtkActor>::New();*
*m_Actor->GetProperty()->SetColor(1.0, 1.0, 1.0);*
*m_Actor->SetMapper(m_Mapper);*
*m_Actor->RotateY(2.0);*

and this way the text rotates around the world center.
How to move the center of rotation to the center of the text?

Thanks,
Dejan Zivkovic
