[vtkusers] vtkScalarBar Title font issue

[John Platt]

Hi Sahil,

You cannot set the font size - it is chosen automatically to fit the region occupied by vtkScalarBarActor. 

If you want to change this behaviour, you will need to change vtkScalarBarActor::SizeTitle().

This is the situation for version 5.4. Since the font size is not changing, I suspect this code has not changed.

HTH

John.

  Hii philippe,
  Im not explicitly setting any mapper to vtkScalarBar object.The default mapper it uses is vtkMapper2D. Im trying to set font by pScalarBarActor->GetTitleTextProperty()->SetFontSize(25);
  Do you know how i can call SetMultipleConstrainedFontSize().


  Thank you for your answer.


  Regards,
  Sahil

    Hello Sahil,

    The size is set by vtkTextMapper::SetMultipleConstrainedFontSize() in order to fix the scalar bar size and orientation.

    Best regards,
    Philippe

      I have created a vtkScalarBarActor object and rendered it on a window. But
      when i try to change the size of the scalarbar title by
      scalarBar->GetTitleTextProperty()->SetFontSize(25)..the size doesnt change
      at all. What will be the problem?
