Detailed Description

An actor that displays text.

Scaled or unscaled

vtkTextActor can be used to place text annotation into a window. When TextScaleMode is NONE, the text is fixed font and operation is the same as a vtkPolyDataMapper2D/vtkActor2D pair. When TextScaleMode is VIEWPORT, the font resizes such that it maintains a consistent size relative to the viewport in which it is rendered. When TextScaleMode is PROP, 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.
