Re: [Boost-users] [GIL] gil_function_requires( view that contains alpha )

Eloi,

I would do something like that (not tested): BOOST_STATIC_ASSERT(mpl::contains::value);

This works just fine.

But I don't know if it is a good idea. Is there a way to do that with gil_function_requires ?

You mean by adding a new concept to gil? I would just go with the metafunction you provided above. What are you trying to do? Some SFINAE? Christian
