Detailed Description

template<typename I, typename F, typename B>
struct mln::lazy_image< I, F, B >

Image values are computed on the fly.

The parameter I is the type of image. The parameter F is the type of function. The parameter B is the type of box.

This image class tage a functor fun and a box box. Access to ima(p) where p include box return fun(b) lazily.
