[Olena-patches] 709: Add a specialization of level::fill for value-wise random accessible images.

https://svn.lrde.epita.fr/svn/oln/trunk/olena Index: ChangeLog from Roland Levillain &lt;roland(a)lrde.epita.fr&gt; Add a specialization of level::fill for value-wise random-accessible images. * tests/morphers/with_lut.cc (main): More static checking of the interface of an image with LUT. Test oln::level::fill on an image with LUT. * oln/level/fill.hh (level::fill(abstract:: mutable_image_being_value_wise_random_accessible<I>&)) (level::impl:: fill(abstract::mutable_image_being_value_wise_random_accessible<I>&)): New. * oln/core/typedefs.hh (oln_fwd_viter, oln_fwd_viter_) (oln_bkd_viter, oln_bkd_viter_, oln_viter, oln_viter_): New macros. * oln/core/gen/bkd_viter_lut.hh (bkd_viter_lut::bkd_viter_lut(const morpher::with_lut<Image, Lut>&)) * oln/core/gen/fwd_viter_lut.hh (fwd_viter_lut::fwd_viter_lut(const morpher::with_lut<Image, Lut>&)) New ctors. oln/core/gen/bkd_viter_lut.hh | 19 ++++++++++++++++++- oln/core/gen/fwd_viter_lut.hh | 21 +++++++++++++++++++-- oln/core/typedefs.hh | 14 +++++++++++++- oln/level/fill.hh | 26 ++++++++++++++++++++++++++ tests/morphers/with_lut.cc | 24 +++++++++++++++++------- 5 files changed, 93 insertions(+), 11 deletions(-) Index: tests/morphers/with_lut.cc --- tests/morphers/with_lut.cc (revision 708) +++ tests/morphers/with_lut.cc (working copy) @@ -114,7 +114,16 @@ add(1, white). add(2, c); + // Type of our image with look-up table. typedef oln::morpher::with_lut<image_t, lut_t> image_with_lut_t; + // Interface check. + mlc::assert_< + mlc_is_not_a_(image_with_lut_t, oln::abstract::mutable_image) + >::check(); + mlc::assert_< + mlc_is_a_(image_with_lut_t, + oln::abstract::mutable_image_being_value_wise_random_accessible) + >::check(); // FIXME: ``ima + lut'' doesn't work.
