Je dis peut-être une bêtise, mais ça me semble dangereux en public.

Je ne prends pas le temps de comprendre pourquoi cette classe. Merci d'ajouter un exemple de code. Mm remarque que la première classe (commantaire, vt...).
+ ** \brief Instantiate a temporary read-only iter morpher. + ** + ** The image will be viewed according to its iterator type. + ** For example, the foo function will print the size of the picture + ** (the bkd_iter_type is used transparently). + ** + ** \code + ** #include <oln/morpher/iter_morpher.hh> + ** #include <oln/basics2d.hh> + ** #include <ntg/all.hh> + ** template <class E> + ** void foo(const oln::abstract::image<E>& img) + ** { + ** oln_iter_type(oln::abstract::image<E>) it(img);

std::cout << std::endl;

Ici tu colles le résultat (pas visible dans la doc). Merci d'ajouter le tout dans les tests.

Sinon, ça donne envie de l'utiliser :) -- Niels
