[Insight-users] C2440 when reinterpret_cast-ing from base to specific class

[itkvtk123 at gmx.net]

Thank you. Your code

reinterpret_cast<GradientDescentType*>(optimizer.GetPointer())->SetRelaxationFactor(0.5);

did the trick.
I knew that the pointer might be the reason, but I was not aware of the GetPointer() function.
