* \class ConvertPixelBuffer
* \brief Class to convert blocks of data from one type to another.
*
* ConvertPixelBuffer has a static method Convert(). It is used by
* itkImageFileReader to convert from an unknown type at run-time to the
* compile-time template pixel type in itkImageFileReader. To work with
* complex pixel types like RGB and RGBA a traits class is used.
* OutputConvertTraits() is the traits class. The default one used is
* DefaultConvertPixelTraits.
