#128: Handle carefully tests using X11
----------------------+-----------------------------------------------------
Reporter: levill_r | Owner: Olena Team
Type: defect | Status: new
Priority: major | Milestone: Olena 1.0ß
Component: Milena | Version: 1.0
Keywords: test |
----------------------+-----------------------------------------------------
Some tests require X11 visualization programs such as `display` (from
!ImageMagick) or `xv`. This is an issue since
* the they might not be installed on the machine;
* the host/session on which tests are executed might not run a X11
display.
IMHO, we could either
1. move them out of the `check` target (and have them launched by the
`check-all`/`check-full` target, or a check-x11 target); or
2. have `configure` check whether the required programs are present, as
well as a (usable) X11 session.
(Maybe the Vaucanson Team ran into such questions; ask them.)

#125: Ambiguity in comparaison with literals
--------------------------------+-------------------------------------------
Reporter: garrigues | Owner: theo
Type: defect | Status: new
Priority: major | Milestone: Olena 1.0ß
Component: Milena | Version: 1.0
Keywords: literals operators |
--------------------------------+-------------------------------------------
This test shows the problem :
{{{
#!cpp
# include <mln/value/gl8.hh>
# include <mln/literal/all.hh>
int main()
{
using mln::value::gl8;
using mln::literal::white;
gl8 b;
b == white;
}
}}}
The compiler can't find the right operator== to compate graylevel with
literals.
Here is the error output :
{{{
test.cc: In function 'int main()':
test.cc:11: error: ISO C++ says that these are ambiguous, even though the
worst conversion for the first is better than the worst conversion for the
second:

Our hand-made build system does not seem to track dependencies very well
in Swilena/Python. Improve this.

#144: Fix load (and maybe save) routine(s) for ASCII-encoded PBM images

Théo discovered on May 28, 2008 that the load routine for ASCII-encoded
PBM (boolean) images was broken (and maybe the save routine, too).
The other ASCII-based Netpbm should be checked as well. Don't close this
ticket until all of these routine have been inspected and declared safe!

In source:trunk/milena/mln/core/internal/image_if_base.hh data trait is
suspect.
For example an image_if from an image1d has always data trait raw !

#131: Implement area closing and attribue closing

Reporter: levill_r | Owner: Olena Team
Type: defect | Status: new
Priority: minor | Milestone: Static 1.0
Component: Milena | Version: 1.0
Keywords: completion dual naming routines algorithms |
--------------------------------------------------------+-------------------
Currently, these files are available:
* source:trunk/morpho/mln/opening_area.hh
* source:trunk/morpho/mln/opening_attribute.hh
but there is no equivalent for closings. Implement them.
BTW, these files and their routines are called `opening_area` and
`opening_attribute`, which is not elegant. Of course the goal is to put
forward the opening term; but IMHO, we should use namespace to do this,
not prefixes. Or rename them to `area_opening` and `attribute_opening`,
which are much more natural. Anyway, any further discussion on the subject
of naming algorithms should be carried on in another ticket.

#170: Get rid of typedef mln::internal::image_base::coord
-------------------------+--------------------------------------------------
Reporter: levill_r | Owner: Olena Team
Type: enhancement | Status: new
Priority: minor | Milestone: Olena 1.0
Component: Milena | Version: 1.0
Keywords: point |
-------------------------+--------------------------------------------------
In source:branches/cleanup-2008/milena/mln/core/internal/image_base.hh,
`mln::internal::image_base` defines a typedef `coord`, which reduces the
genericity of this class:
{{{
#!cpp
/// Coordinate associated type.
typedef mln_deduce(S, site, coord) coord;
}}}
A consequence is that the site type `S::site` must define an associated
type `coord` (hence `std::vector<point2d>` is not a valid site type), yet
we had decided that there should be no prerequisites on the interfaces of
sites in Milena.

-------------------------+--------------------------------------------------
See source:branches/cleanup-2008/milena/mln/topo/complex.hh
* Store only the indices of adjacent faces in `complex_data<D>`: we don't
really need actual faces there, and it costs a lot (memory, execution
time, design complexity, etc.)
* Then (or concurrently) simplify the design: use an array of array
instead of an ad hoc type list.
* The '''dynamic''' access(es) to the set of ''n''-faces of a complex
(e.g., `mln::complex::nfaces(unsigned)`) has (have) a linear complexity!
We should get rid of that. We could create an index at the creation of
the complex, mapping dynamic dimension numbers to the corresponding
(static) mixin/data.

* Get rid of superfluous dynamic allocations (w.r.t. vertices & edges
handling).
* Move properties attached to vertices and edges out of the graph (this
should allow the merging of `util::graph` and
`util::internal::graph_base`.
* Allow the removal of vertices and edges. Don't forget to warn users
about the invalidation of vertex and edge ids (handlers).
* Stop using the term « id » (« identifier ») for vertices and edges, and
prefer the term « handler » ? (The BGL call them « descriptors ».)
All these changes might bring us closer to the BGL' `adjacency_list`. See
how we could factor things, while not requiring a dependency on the BGL.
