vtkLabeledDataMapper is a mapper that renders text at dataset points. Various items can be labeled including point ids, scalars, vectors, normals, texture coordinates, tensors, and field data components.
The format with which the label is drawn is specified using a printf style format string. The font attributes of the text can also be set (font style, size, bold, italic, shadow). The color of the text is controlled by the actor2D's color property (i.e., the actor associated with this mapper).
By default, all the components of multi-component data such as vectors, normals, texture coordinates, tensors, and multi-component scalars are labeled. However, you can specify a single component if you prefer. (Note: the label format specifies the format to use for a single component. The label is creating by looping over all components and using the label format to render each component.)
-
Warning:
-
Use this filter in combination with vtkSelectVisiblePoints if you want to label only points that are visible. If you want to label cells rather than points, use the filter vtkCellCenters to generate points at the center of the cells. Also, you can use the class vtkIdFilter to generate ids as scalars or field data, which can then be labeled.

Member Function Documentation
| vtkLabeledDataMapper* vtkLabeledDataMapper::New |
( |
|
) |
[static] |
|
|
|
Instantiate object with font size 12 of font Arial (bolding, italic, shadows on) and %-#6.3g label format. By default, point ids are labeled.
Reimplemented from vtkMapper2D. |
| virtual const char* vtkLabeledDataMapper::GetClassName |
( |
|
) |
[virtual] |
|
|
|
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 vtkMapper2D. |
| int vtkLabeledDataMapper::IsTypeOf |
( |
const char * |
type |
) |
[static] |
|
|
|
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.

( |
const char * |
type |
) |
[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.

[virtual] |
|
|
|
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 vtkMapper2D. |
|

|
| virtual void vtkLabeledDataMapper::ReleaseGraphicsResources |
( |
vtkWindow * |

[virtual] |
|
|
|

( |
int |
|
) |
[virtual] |
|
|
|
Specify which data to plot: scalars, vectors, normals, texture coords, tensors, or field data. If the data has more than one component, use the method SetLabeledComponent to control which components to plot. |
