[vtkusers] vtkCaptionActor2D text appears chopped

[Roberto Garrido]

Thanks Dave,

 

We are using Vtk 5.10.0.

Is there any way to solve it without switching to development branch?

 

My best,

Robert.

Hi Roberto,

 

We've recently fixed a number of bugs in the text rendering code in the
development branch. I'm adding your test case to our regression tests to
check if we still see this with the new rendering backend.

 

Which version of VTK are you seeing this in?

 

Dave

Hi,

 

We have added a vtkCaptionActor2D to our scene, but the text appears
chopped, and we don't know why.

A simple and compilable example that shows the output text chopped is sent
attached.  Also, an screenshot at the bottom.

Could anyone try to reproduce the error?

 

 

Thanks in advance.

My best,

Robert.
