Hi, Using activiz 5.8, the shadow is messy when applied to a vtkTextActor, while it is perfect when applied to a vtkCornerAnnotation. It might be related to this opened bug: http://www.paraview.org/Bug/print_bug_page.php?bug_id=9618 But I would love to know why vtkCornerAnnotation is immune to this bug, any idea ? Regards.
