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

Hi everybody,
I would like to know if there is an easy way to check if a view type
contains an alpha channel.
I would do something like that (not tested):
BOOST_STATIC_ASSERT(mpl::contains<typename color_space_type<Pixel>::type,
alpha_t>::value);
But I don't know if it is a good idea.
Is there a way to do that with gil_function_requires ?
Thanks & respect !
Eloi.
