plus d'un).

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);
oln_fwd_iter.
+ ** for_all(it)
+ ** {
+ ** std::cout << it.row() << " " << it.col() <<
std::endl;
std::cout << it;
+ ** break;
pas break
+ ** }
std::cout << std::endl;
+ ** }
+ ** int main()
+ ** {
+ ** const oln::image2d<ntg::rgb_8> imc =
oln::load(IMG_IN "lena.ppm");
ntg::int_u8 [...] test-cmap.pgm
(petite image).
+ ** assert(imc.has_impl());
+ **
foo(oln::morpher::iter_morph<oln_bkd_iter_type_(oln::image2d<ntg::rgb_8>)>(imc));
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 :)
