[Olena-patches] milena r1630: Fix convertions between the 4 graylevels types

URL: https://svn.lrde.epita.fr/svn/oln/trunk/milena ChangeLog: 2008-01-04 Matthieu Garrigues &lt;garrigues(a)lrde.epita.fr&gt; Fix convertions between the 4 graylevels types. * mln/value/graylevel.hh, * mln/value/graylevel_f.hh, * mln/value/internal/gray_.hh, * mln/value/internal/gray_f.hh: All these convertion now work: gray_f -> gray_<n>, gray_f -> graylevel<n>, gray_f -> graylevel_f, gray_<n> -> gray_f, gray_<n> -> graylevel<n>, gray_<n> -> graylevel_f, graylevel_f -> gray_f, graylevel_f -> graylevel<n>, graylevel_<n> -> gray_<n>, graylevel_<n> -> graylevel_f<n>. * tests/value/graylevel.cc: Add more tests for convertions. --- mln/value/graylevel.hh | 84 +++++++++------------------ mln/value/graylevel_f.hh | 96 ++++++++++++++++--------------- mln/value/internal/gray_.hh | 15 ---- mln/value/internal/gray_f.hh | 130 +++++++++++++++++++++++++++++++------------ tests/value/graylevel.cc | 41 ++++++++++--- 5 files changed, 206 insertions(+), 160 deletions(-) Index: trunk/milena/tests/value/graylevel.cc =================================================================== --- trunk/milena/tests/value/graylevel.cc (revision 1629) +++ trunk/milena/tests/value/graylevel.cc (revision 1630) @@ -56,10 +56,17 @@ // } +#define test_convertion(T1, T2, VAL) \ +{ \ + T1(T2(VAL));
