Member Function Documentation

◆ getColor()

template<typename PointT >
vtkSmartPointer< vtkDataArray > pcl::visualization::PointCloudColorHandlerLabelField< PointT >::getColor ( ) const
overridevirtual

Obtain the actual color for the input dataset as a VTK data array.

Deriving handlers should override this method. The default implementation is provided only for backwards compatibility with handlers that were written before PCL 1.10.0 and will be removed in future.

Returns
smart pointer to VTK array if the operation was successful (the handler is capable and the input cloud was given), a null pointer otherwise

Reimplemented from pcl::visualization::PointCloudColorHandler< PointT >.
