let's say I have

template <int Dimension, typename T>
class Image {
    ...
    Format GetFormat() const;
}

and now I want to create template specialised implementations for GetFormat that only care about the Dimension however. like this for example:

template<>
Image<1, ???>::GetFormat() const {
    return Format::Alpha8;
}

template<>
Image<4, ???>::GetFormat() const {
    return Format::Rgba8888;
}

So in the specialized implementation I only care about the first template parameter that should be used no matter what the second parameter is.

What's the propper syntax for this?

specialize the class, not the member function (idk if there is a way to do what you want) – Alberto Sinigaglia Jul 23 '20 at 17:52
