[vtk-developers] Question regarding vtkTextActor3D

[David Lonie]

Hi Adam,

There have been many text handling improvements since 5.10.1 -- the entire
text rendering engine was rewritten around the v6 release. Your issue was
likely fixed in the new code. Please let us know if you experience the same
issue on a newer version of VTK.

Thanks,
Dave
