[Olena-patches] 3180: Handle rgb and hsl conversions in from_to and remove to_rgb.

* headers.mk: remove to_rgb.hh from distribution. * mln/convert/all.hh: remove to_rgb.hh. * mln/convert/from_to.hxx: add more predeclarations. * mln/convert/impl/from_value_to_value.hh: if no value concept is caught in the dispatch, try to call a from_to_ overload. * mln/fun/v2v/rgb_to_hsl.hh: add new global variables of function converting rgb16 to hsl. * mln/value/hsl.hh, * mln/value/rgb.hh: add new from_to_ overloads. * tests/convert/Makefile.am, * tests/convert/to_hsl.cc, * tests/convert/to_rgb.cc: new tests. Test conversions with rgb<n> and hsl<h,s,l> using from_to. * mln/convert/to_rgb.hh: remove. Useless since conversions are now done thanks to from_to. * tests/unit_test/Makefile.am, * tests/unit_test/mln_convert_to_rgb.cc: remove unit_test related to to_rgb.hh. * mln/fun/v2v/rgb_to_hsl.hh: do not include hsl.hh anymore. --- milena/ChangeLog | 33 ++++ milena/headers.mk | 1 - milena/mln/convert/all.hh | 5 +- milena/mln/convert/from_to.hxx | 25 +++ milena/mln/convert/impl/from_value_to_value.hh | 27 ++- milena/mln/fun/v2v/rgb_to_hsl.hh | 15 +- milena/mln/value/hsl.hh | 195 +++++++++++++++++--- milena/mln/value/rgb.hh | 67 +++++++- milena/tests/convert/Makefile.am | 4 + .../convert/to_rgb.hh => tests/convert/to_hsl.cc} | 75 ++------ .../convert/all.hh => tests/convert/to_rgb.cc} | 43 ++--- milena/tests/unit_test/Makefile.am | 2 - milena/tests/unit_test/mln_convert_to_rgb.cc | 11 - 13 files changed, 364 insertions(+), 139 deletions(-) rename milena/{mln/convert/to_rgb.hh => tests/convert/to_hsl.cc} (54%) copy milena/{mln/convert/all.hh => tests/convert/to_rgb.cc} (68%) delete mode 100644 milena/tests/unit_test/mln_convert_to_rgb.cc diff --git a/milena/ChangeLog b/milena/ChangeLog index 3da59ee..6e30fb1 100644 --- a/milena/ChangeLog +++ b/milena/ChangeLog @@ -1,3 +1,36 @@ +2009-01-20 Guillaume Lazzara &lt;z(a)lrde.epita.fr&gt; + + Handle rgb and hsl conversions in from_to and remove to_rgb. + + * headers.mk: remove to_rgb.hh from distribution. + + * mln/convert/all.hh: remove to_rgb.hh. + + * mln/convert/from_to.hxx: add more predeclarations. + + * mln/convert/impl/from_value_to_value.hh: if no value concept is + caught in the dispatch, try to call a from_to_ overload. + + * mln/fun/v2v/rgb_to_hsl.hh: add new global variables of function + converting rgb16 to hsl. + + * mln/value/hsl.hh, + * mln/value/rgb.hh: add new from_to_ overloads. + + * tests/convert/Makefile.am, + * tests/convert/to_hsl.cc, + * tests/convert/to_rgb.cc: new tests.
