Hello,
I'am trying to upgrade from vtk5.0.4 to vtk5.2.1, and I have two
problems with the rendering of vtkTextActor.
Basically :
- the shadow property looks rather strange in 5.2.1 compared to 5.0.4
- accuentuated characters (é, è...) are no longer displayed in 5.2.1
Herebelow, a small test program that reproduces the behaviour is given.
I also joined links to illustrate the graphical output obtained with :
- vtk5.0.4 -> http://www.imageshare.web.id/images/mjg8s8miucbecde84rh0.png
- vtk5.2.1 http://www.imageshare.web.id/images/x1ijylcbtox56lbzn12.png
I compiled both vtk version with VC++2005 under WinVista.
Any hints of where the problem may come from?
Thanks
JD
