[Olena-patches] 2105: Add the ability to load images of built-in (POD) values.

https://svn.lrde.epita.fr/svn/oln/trunk/milena Index: ChangeLog from Roland Levillain &lt;roland(a)lrde.epita.fr&gt; Add the ability to load images of built-in (POD) values. * mln/io/pnm/load.hh (mln::io::pnm::read_value(std::ifstream&, V&): Turn into... (mln::io::pnm::read_value(std::ifstream&, value::Scalar<V>&)): ...this. (mln::io::pnm::read_value(std::ifstream&, V&): New overload. * mln/value/int_u8.hh (mln::io::pnm::int_u8): Use a fully qualified type name to help swig wrap this typedef. * mln/io/pgm/save.hh: Typo in comment. io/pgm/save.hh | 2 +- io/pnm/load.hh | 28 ++++++++++++++++++---------- value/int_u8.hh | 2 +- 3 files changed, 20 insertions(+), 12 deletions(-) Index: mln/value/int_u8.hh --- mln/value/int_u8.hh (revision 2104) +++ mln/value/int_u8.hh (working copy) @@ -44,7 +44,7 @@ /// Alias for unsigned 8 bit integers. - typedef int_u<8> int_u8; + typedef mln::value::int_u<8> int_u8; } // end of namespace mln::value Index: mln/io/pgm/save.hh --- mln/io/pgm/save.hh (revision 2104) +++ mln/io/pgm/save.hh (working copy) @@ -78,7 +78,7 @@ inline void save(const Image<I>& ima, const std::string& filename) { - // FIXME : this is to restrictive.
