#244: Make use of \snippet command with doxygen -------------------------+-------------------------------------------------- Reporter: lazzara | Owner: Olena Team Type: enhancement | Status: new Priority: major | Milestone: Olena 1.2 Component: Milena | Version: 1.0 Keywords: | -------------------------+-------------------------------------------------- Sample codes inserted in the Doxygen documentation are currently extracted from full source codes using a shell script. It enables the possibility to check code compilation and give full working code to the users. Since version 1.7.5, Doxygen added a new command, \snippet, which has this functionality of splitting full code examples easily. We should use it and remove all the current scripts. -- Ticket URL: <https://trac.lrde.org/olena/ticket/244> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

Write a program and include these files: #include <mln/core/var.hh> #include <mln/core/image/image2d.hh> #include <mln/debug/iota.hh> #include <mln/debug/println.hh> #include <mln/pw/image.hh> You will be able to use p_array and sub_image without including their related files. Unnecessary includes slow down compilation and is damaging. -- Ticket URL: <https://trac.lrde.org/olena/ticket/218> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #208: Fix dependencies of the HTML documentation generation?

#208: Fix dependencies of the HTML documentation generation? ----------------------+----------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: defect | Status: new Priority: minor | Milestone: Olena 1.1 Component: Milena | Version: 1.0 Keywords: doc | ----------------------+----------------------------------------------------- The generation of the HTML documentation requires a file named `html.sty`, which is not provided by HeVeA, but by latex2html. Is that right? I thought we only had a dependency on the former, not the latter. -- Ticket URL: <https://trac.lrde.org/olena/ticket/208> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

[Olena] #219: Add \internal in the documentation of internal code

#219: Add \internal in the documentation of internal code ---------------------+------------------------------------------------------ Reporter: lazzara | Owner: Olena Team Type: defect | Status: new Priority: major | Milestone: Olena 1.1 Component: Milena | Version: 1.0 Keywords: | ---------------------+------------------------------------------------------ Currently, in order to not expose the internal code in the user documentation, everything in the internal and trait namespaces is ignored during the doc generation. The main issue is that inherited members are not shown in the documentation of the classes exposed to the user. The only way to ask Doxygen to show inherited members and not to show internal documentation is to add \internal in the documentation of internal code. -- Ticket URL: <https://trac.lrde.org/olena/ticket/219> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.

#235: Support GraphicsMagick++ and drop support for ImageMagick++ -------------------------+-------------------------------------------------- Reporter: levill_r | Owner: Olena Team Type: proposal | Status: new Priority: major | Milestone: Olena 1.1 Component: Milena | Version: 1.0 Keywords: io external | -------------------------+-------------------------------------------------- !GraphicsMagick (http://www.graphicsmagick.org/) seems to provide a framework more modern than !ImageMagick's (http://www.imagemagick.org) in particular regarding multi-core support. Moreover Fabien has discovered weird behaviors (#210) and Buildbot has also recently exhibited run time errors that did not surface before (https://buildfarm.lrde.org/buildfarm/oln/builders/i486-linux-gnu- gcc-4.1/builds/539/steps/check/logs/stdio) -- though I don't know who's the culprit here. -- Ticket URL: <https://trac.lrde.org/olena/ticket/235> Olena <http://olena.lrde.epita.fr> Olena, a generic and efficient C++ image processing library.
