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.

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource. |
|
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource. |

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource. |
|
Construct object with no string set and backing enabled. Reimplemented from vtkPolyDataSource. |
|
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkSource. |
|
Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkPolyDataSource. |
|
Set/Get the background color. Default is black (0,0,0). Alpha is always 1. |
|
Controls whether or not a background is drawn with the text. |
|
Set/Get the foreground color. Default is white (1,1,1). ALpha is always 1. |
|
Set/Get the text to be drawn. |
