https://svn.lrde.epita.fr/svn/oln/branches/cleanup-2008/milena Index: ChangeLog from Thierry Geraud &lt;thierry.geraud(a)lrde.epita.fr&gt; Fix a couple of bugs and augment tutorial examples. * doc/tutorial/examples/p_array.cc: Augment with a test on p_array update. * doc/tutorial/examples/p_array.2.cc: Augment with index manipulation. * doc/tutorial/examples/p_vaccess.cc: Augment with extra output. * mln/trait/site_set/status.txt (pset_array): Fix status. * mln/core/p_vaccess.hh (set_1_): Fix return type. * mln/core/p_double.hh (super): Rename that private typedef as... (super_): ...this. (change_target): New overriding in p_double_piter. That fixes a bug since such iterators have to perform some extra code (w.r.t. the inherited method) when setting the site set. doc/tutorial/examples/p_array.2.cc | 9 +++ doc/tutorial/examples/p_array.cc | 9 +++ doc/tutorial/examples/p_vaccess.cc | 85 +++++++++++++++++++++++++++++++------ mln/core/p_double.hh | 19 ++++++-- mln/core/p_vaccess.hh | 4 - mln/trait/site_set/status.txt | 3 - 6 files changed, 110 insertions(+), 19 deletions(-) Index: doc/tutorial/examples/p_array.cc --- doc/tutorial/examples/p_array.cc (revision 2157) +++ doc/tutorial/examples/p_array.cc (working copy) @@ -75,6 +75,7 @@ << index_of_in(p, arr2) << " in arr2, #" << index_of_in(p, arr1) << " in arr1" << std::endl; } + std::cout << std::endl; } mln_invariant(arr2 < arr1); @@ -89,6 +90,14 @@ } } + { + // Fun stuff: + + arr1[0] = point2d(0,0); + picture(arr1); + picture(arr2); + } + } } Index: doc/tutorial/examples/p_array.2.cc --- doc/tutorial/examples/p_array.2.cc (revision 2157) +++ doc/tutorial/examples/p_array.2.cc (working copy) @@ -81,4 +81,13 @@ // FIXME: j does NOT convert to int because index is NOT a proxy // NOTA: make index be a proxy, so equip it with every op it needs. + + for (i = 0; i < n; i = i + 1) + { + std::cout << "i=" << i << ": "; + for_all(j) + std::cout << arr[(int(j.to_site()) + n) % n] << ' '; + std::cout << std::endl; + } + } Index: doc/tutorial/examples/p_vaccess.cc --- doc/tutorial/examples/p_vaccess.cc (revision 2157) +++ doc/tutorial/examples/p_vaccess.cc (working copy) @@ -3,6 +3,7 @@ # include <mln/value/int_u8.hh> # include <mln/level/fill.hh> +# include <mln/level/paste.hh> # include <mln/debug/println.hh> # include <mln/util/timer.hh> # include <mln/labeling/blobs.hh> @@ -13,6 +14,8 @@ # include <mln/pw/all.hh> # include <mln/convert/from_to.hh> +# include <mln/core/var.hh> + template <typename I, typename S> @@ -64,9 +67,49 @@ mlc_equal(Arr::element, p_run2d)::check(); Arr arr; - convert::from_to(lab | (pw::value(lab) != pw::cst(0u)), arr); + mln_VAR(sub, lab | (pw::value(lab) != pw::cst(0u))); + debug::println(sub); + + convert::from_to(sub, arr); mln_assertion(arr.nsites() == n); + { + std::cout << "arr = "; + mln_piter_(Arr) p(arr); + for_all(p) + std::cout << p << ' '; + std::cout << std::endl; + } + + std::cout << std::endl; + + { + for (unsigned l = 0; l <= nlabels; ++l) + { + std::cout << "arr(" << l << ") = "; + mln_piter_(p_runs2d) p(arr(l)); + for_all(p) + std::cout << p << ' '; + std::cout << std::endl; + } + } + + std::cout << std::endl; + + { + for (unsigned l = 0; l <= nlabels; ++l) + { + std::cout << "arr(" << l << ") = "; + mln_iter_(util::set<p_run2d>) r(arr(l).set_hook_()); + for_all(r) + std::cout << r << ' '; + std::cout << std::endl; + } + } + + std::cout << std::endl; + + std::cout << "arr in " << arr.bbox() << std::endl; for (unsigned l = 0; l <= nlabels; ++l) { std::cout << l << ": #" << arr(l).nsites(); @@ -75,22 +118,40 @@ std::cout << std::endl; } std::cout << std::endl; - } { - p_runs2d rs; - convert::from_to(ima, rs); - mln_assertion(rs.bbox() == ima.bbox()); - - image2d<int_u8> ima_(ima.domain()); + image2d<int> ima_(arr.bbox()); level::fill(ima_, 0); - for (unsigned r = 0; r < rs.nelements(); ++r) - { - mln_piter_(p_run2d) p(rs[r]); - for_all(p) - ima_(p) = r + 1; + for (unsigned l = 1; l <= nlabels; ++l) + for (unsigned r = 0; r < arr(l).nelements(); ++r) + level::paste(pw::cst(10 * l + r) | arr(l)[r], ima_); + debug::println(ima_); } + + { + image2d<int> ima_(arr.bbox()); + level::fill(ima_, 0); + for (unsigned l = 1; l <= nlabels; ++l) + if (arr(l).nsites() > 1) + level::paste(pw::cst(l) | arr(l), ima_); debug::println(ima_); } + } + +// { +// p_runs2d rs; +// convert::from_to(ima, rs); +// mln_assertion(rs.bbox() == ima.bbox()); + +// image2d<int_u8> ima_(ima.domain()); +// level::fill(ima_, 0); +// for (unsigned r = 0; r < rs.nelements(); ++r) +// { +// mln_piter_(p_run2d) p(rs[r]); +// for_all(p) +// ima_(p) = r + 1; +// } +// debug::println(ima_); +// } } Index: mln/trait/site_set/status.txt --- mln/trait/site_set/status.txt (revision 2157) +++ mln/trait/site_set/status.txt (working copy) @@ -43,7 +43,8 @@ ok p_vaccess ok line2d +rm pset_array.hh + ??
