Detailed Description
An actor that displays text. Scaled or unscaled.

1.4
vtkTextActor can be used to place text annotation into a window. When ScaledText is false, the text is fixed font and operation is the same as a vtkTextMapper/vtkActor2D pair. When ScaledText is true, the font resizes such that the text fits inside the box defined by the position 1 & 2 coordinates. This class replaces the deprecated vtkScaledTextActor and acts as a convenient wrapper for a vtkTextMapper/vtkActor2D pair. Set the text property/attributes through the vtkTextProperty associated to this actor.
