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>;
