/** \class VTKImageExport
* \brief Connect the end of an ITK image pipeline to a VTK pipeline.
*
* VTKImageExport can be used at the end of an ITK image pipeline to
* connect with a VTK pipeline that begins with vtkImageImport.
* Callbacks provided by VTKImageExport are registered with
* vtkImageImport to connect the pipeline execution together. Once
* connected, update requests coming through the VTK pipeline are
* automatically propagated to the ITK pipeline.
*
* While VTKImageExportBase provides the pipeline functionality
* independent of image type, instances must be created through
* VTKImageExport. This class provides the implementations for
* callbacks that depend on the image type.
*
* Note that not all image types will work correctly. VTK will only
* support images of 1, 2, or 3 dimensions. Scalar value types can be
* one of: float, double, char, unsigned char, short, unsigned short,
* int, unsigned int, long, unsigned long.
*
* Currently VTKImageExport does not support pixel types with multiple
* components (like RGBPixel).
*
* \ingroup IOFilters
