void vtkFreeTypeLabelRenderStrategy::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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 vtkObject.

static vtkTypeBool vtkFreeTypeLabelRenderStrategy::IsTypeOf ( const char * type )

static

virtual vtkTypeBool vtkFreeTypeLabelRenderStrategy::IsA ( const char * name )

virtual

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 vtkLabelRenderStrategy.

Render a label at a location in world coordinates.

Must be performed between StartFrame() and EndFrame() calls.
