// .NAME vtkTextSource - create polygonal text
|
|
// .SECTION 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.
