[Olena-patches] milena r3684: Remove check save + modification in compute attribute method

URL: https://svn.lrde.epita.fr/svn/oln/trunk/milena ChangeLog: 2009-04-17 Edwin Carlinet &lt;carlinet(a)lrde.epita.fr&gt; Remove check save + modification in compute attribute method. * mln/io/pgm/save.hh: Remove static check unit_8 while saving pgm. * mln/morpho/tree/compute_attribute_image.hh: Add extra argument where the accumulator image will be store. --- io/pgm/save.hh | 3 - morpho/tree/compute_attribute_image.hh | 57 ++++++++++++++++++++++----------- 2 files changed, 38 insertions(+), 22 deletions(-) Index: trunk/milena/mln/morpho/tree/compute_attribute_image.hh =================================================================== --- trunk/milena/mln/morpho/tree/compute_attribute_image.hh (revision 3683) +++ trunk/milena/mln/morpho/tree/compute_attribute_image.hh (revision 3684) @@ -35,6 +35,7 @@ /// /// \todo Specialize for low quant (and try fastest). +# include <mln/core/routine/duplicate.hh> # include <mln/core/concept/image.hh> # include <mln/morpho/tree/data.hh> # include <mln/trait/accumulators.hh> @@ -42,7 +43,6 @@ # include <mln/data/fill.hh> - namespace mln { @@ -52,25 +52,38 @@ namespace tree { - /// Compute a tree with a parent relationship between sites. - /// - /// Warning: \p s translates the ordering related to the - /// "natural" childhood relationship.
