## Detailed Description

template<typename ... Views>
class boost::gil::any_image_view< Views >

Represents a run-time specified image view. Models HasDynamicXStepTypeConcept, HasDynamicYStepTypeConcept, Note that this class does NOT model ImageViewConcept.

CLASS any_image_view

Represents a view whose type (color space, layout, planar/interleaved organization, etc) can be specified at run time. It is the runtime equivalent of `image_view`. Some of the requirements of ImageViewConcept, such as the `value_type` alias cannot be fulfilled, since the language does not allow runtime type specification. Other requirements, such as access to the pixels, would be inefficient to provide. Thus `any_image_view` does not fully model ImageViewConcept. However, many algorithms provide overloads taking runtime specified views and thus in many cases `any_image_view` can be used in places taking a view.

To perform an algorithm on any_image_view, put the algorithm in a function object and invoke it by calling `variant2::visit(algorithm_fn, runtime_view)`;
