[ITK Community] [Insight-users] Typedef overloading on derived classes

[Tim Allman]

It's not entirely clear what you want to do but it sounds like you want 
to make a typedef which describes a partially specialised template class 
instead of the fully specialised typedefs we usually use.

Are you trying to do something like this?

template <unsigned Dimension>
typedef itk::Image<float, Dimension> FloatImageType<Dimension>;

C11 allows this with a rather strange syntax.

template <unsigned Dimension>
using FloatImageType = itk::Image<float, Dimension>;

To make an instance of a three dimensional float image:
FloatImageType<3> image;

I did this to make a partially specialised template to create fixed 
length arrays of length 4 to hold different types.

template <typename TValueType>
using ParamVector = itk::FixedArray<TValueType, 4>;
