Dear list, I think GIL is not able to convert an any_image_view to its const equivalent or I don't know how to do it. The variant class checks in its constructor if it can hold the given type but it doesn't have a constructor to convert an any_image_view from one to another. Here is a simple piece of code declaring two any_image_views: typedef boost::gil::any_image_view< boost::mpl::vector< boost::gil::rgba8_view_t >
image_view;
typedef boost::gil::any_image_view< boost::mpl::vector< boost::gil::rgba8c_view_t >
const_image_view;
Now when I try to construct a const_image_view from an image_view I get an std::bad_cast exception. What can I do about it?
