https://svn.lrde.epita.fr/svn/oln/trunk/milena Index: ChangeLog from Thierry Geraud <thierry.geraud@lrde.epita.fr> Get rid of the former property mechanism for value types. Start cleaning the histogram-related test. * tests/histo_compute.cc: Rename as... * tests/histo/compute.cc: ...this. Activate the test with int_s<5>. * tests/accu_all.cc: Inactivate tests on "median< value::set<bool> >" and "min_h< value::set<bool> >" since traits for bool are not equiped with min() and max(). * tests/Makefile.am (SUBDIRS): Sort, Add histo. (histo_compute_SOURCES): Remove. * tests/io_pbm.cc: Simplify. * tests/histo/Makefile.am (check_PROGRAMS): New. (compute_SOURCES, TESTS): New. Preparing to get rid of former property mechanism for value types. * mln/value/props.hh (mln_card_): Move... * mln/trait/value_.hh: ...here and rename as... (mln_card): ...this. * mln/value/props.hh (mln_value_sum, mln_value_kind, mln_value_card_): Remove. (mln_is_lowq): Remove. (mln_min, mln_max): Move... * mln/trait/value_.hh: ...here. * mln/trait/value_.hh (mln_trait_value_card): Rename as... (mln_card): ...this. (mln_value_quant_from_card): Rename as... (mln_value_quant_from_): ...this. (mln_value_card_from_): New macro. (mln_nbits, mln_epsilon): New. * mln/trait/value/nature.hh (matrix): New. Now get rid of value "props". * mln/value/props.hh: Remove. (convert_): Move into... * mln/value/internal/convert.hh: ...this new file. (convert_<bool>): New specialization. Propagate changes. * tests/value_bool.cc, * mln/trait/images.hh, * mln/trait/value/print.hh, * mln/core/macros.hh, * mln/math/round_sat.hh, * mln/metal/mat.hh, * mln/metal/vec.hh, * mln/arith/revert.hh, * mln/arith/revert.spe.hh, * mln/level/sort_points.hh, * mln/level/transform.spe.hh, * mln/level/transform.hh, * mln/level/stretch.hh, * mln/accu/min.hh, * mln/accu/max.hh, * mln/accu/min_max.hh, * mln/accu/sum.hh, * mln/value/proxy.hh, * mln/value/graylevel.hh, * mln/value/lut_vec.hh, * mln/value/ops.hh, * mln/value/gray.hh, * mln/value/float01_.hh, * mln/value/all.hh, * mln/value/quat.hh, * mln/value/int_s.hh, * mln/value/int_u.hh, * mln/value/int_u_sat.hh, * mln/value/set.hh, * mln/value/float01.hh, * mln/value/builtin/symbolics.hh, * mln/value/builtin/floatings.hh, * mln/value/builtin/integers.hh, * mln/value/rgb.hh, * mln/value/float01_f.hh, * mln/value/label.hh, * mln/fun/v2v/saturate.hh, * mln/morpho/Rd.hh, * mln/norm/l1.hh, * mln/norm/l2.hh: Update.
