Detailed Description

2D text annotation

Date:: 2002/11/11 21:41:40

Revision:: 1.48

vtkTextMapper provides 2D text annotation support for vtk. It is a vtkMapper2D that can be associated with a vtkActor2D and placed into a vtkRenderer or vtkImager.

To use vtkTextMapper, specify an input text string.
