vtkTextSource - create polygonal text

Description:

vtkTextSource converts a text string into polygons. This way you can insert text into your renderings. It uses the 9x15 font from X Windows. You can specify if you want the background to be drawn or not. The characters are formed by scan converting the raster font into quadrilaterals. Colors are assigned to the letters using scalar data. To set the color of the characters with the source's actor property, set BackingOff on the text source and ScalarVisibilityOff on the associated vtkPolyDataMapper. Then, the color can be set using the associated actor's property. vtkVectorText generates higher quality polygonal representations of characters.
