Summary

0008372: Differences in display of vtkTextActors between vtk5.0.4 and vtk5.2.1 (shadow and accentuated characters)

Description

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 files to illustrate the graphical output obtained in each case.

Note: both vtk versions were compiled with VC++2005 under WinVista.

Additional Information

// Example code to show the difference in rendering of vtkTextActor
// Compiled and run either with vtk5.0.4 or vtk5.2.1
// For the graphical output of each version see attached file.
