[Insight-users] Set LBFGSB bounds by GetOptimizer()

[Seth Gilchrist]

Hello all,
I got this code to compile and run using a reinterpret_cast

reinterpret_cast<itk::LBFGSBOptimizer
*>(this->m_Registration->GetOptimizer())->SetBoundSelection( boundSelect );
reinterpret_cast<itk::LBFGSBOptimizer
*>(this->m_Registration->GetOptimizer())->SetUpperBound( upperBound );
reinterpret_cast<itk::LBFGSBOptimizer
*>(this->m_Registration->GetOptimizer())->SetLowerBound( lowerBound );

If there is a better way, I'm open to suggestions!

Thanks,
Seth
