[Olena-patches] 3567: Relax a couple of contraints related to labels and integers.

https://svn.lrde.epita.fr/svn/oln/trunk/milena Index: ChangeLog from Thierry Geraud &lt;thierry.geraud(a)lrde.epita.fr&gt; Relax a couple of contraints related to labels and integers. * mln/debug/colorize.hh: Relax the Symbolic constraint. That allows for colorizing images containing integers. * mln/value/int_u.hh (next): New. That allows for images containing integers to be processed as labeled images. debug/colorize.hh | 4 ++-- value/int_u.hh | 15 +++++++++++++-- 2 files changed, 15 insertions(+), 4 deletions(-) Index: mln/debug/colorize.hh --- mln/debug/colorize.hh (revision 3565) +++ mln/debug/colorize.hh (working copy) @@ -1,4 +1,4 @@ -// Copyright (C) 2008 EPITA Research and Development Laboratory +// Copyright (C) 2008, 2009 EPITA Research and Development Laboratory // (LRDE) // // This file is part of the Olena Library.
