vtkLabeledDataMapper

Section: Visualization Toolkit Rendering Classes

Usage

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 be set through the vtkTextProperty associated to 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.)

To create an instance of class vtkLabeledDataMapper, simply invoke its constructor as follows

  obj = vtkLabeledDataMapper
