[ITK] [ITK-users] Future of WrapITK

[Paavolainen Lassi]

Thank you Michka for this information and for your work with wrapping as well.

We are developing with Python 2.7 so fixes for Python 3 is not important for us but I can help do some testing. Do you know if the developments in wrapping will effect the Visual Studio compilers? I might get my hands to Visual Studio 2008 but then I need to leave off some of our latest modules that are using C++11 specification. It probably gives some issues if ITK is built with Visual Studio 2008 and external filter with Visual Studio 2013.

I was aware of your OS X binaries but the issue is that we also have our own ITK classes that needs to be wrapped so we cannot use these.

We are using many image filters as well as the registration framework from the ITK. I think I read that the registration framework is not fully usable in SimpleITK.

I'll follow the developments for ITK 4.8 and will test and help in anyways possible. Thank you all for your efforts with ITK wrappings.

Cheers,
Lassi

Hi

we have been working on Wrapping so the development is going on.
Some small improvements were made for ITK 4.7.

I ported most of the code to Python3, but we have still an error which we have been working on, but is tricky to tackle.
I hope to get this done for ITK 4.8, and it will need some testing.

Fixing the problem for Clang is also under way, I don’t know how much resources we can put in it but I am hoping also for ITK 4.8, though I can not
promise anything here.

If you really need ITK wrappings on OS X, you can try my ITK binaries for homebrew: https://github.com/iMichka/homebrew-MacVTKITKPythonBottles
(Please open a ticket on the github page if you have any trouble with these binaries).

If you would like to help, there are a lot of things to do on the wrapping code.
(Writing examples for the ITK examples website is a good way to start with).

For SimpleITK vs Wrapping, it all depends on what image types you want to analyse, and what filters you want to use.

Hi,

I'm developing software that uses ITK through Python wrapping. After some period of slower development progress we are now moving from ITK 3.20 to ITK 4.x. The software is developed and packages are released for 64-bit Windows, Linux and OS X. The problem is that ITK 4.6.1 with Python wrappings can be built only for Linux. It seems that there is no way around the issues with GCCXML and new Visual Studio in Win or Clang in OS X 10.9.

The issue has been raised before in: http://www.itk.org/pipermail/insight-users/2014-July/050562.html

To follow up that question, has there been any progress related to GCCXML replacement or development of GCCXML to support new Visual Studio and Clang? Are there still plans for this or will wrapITK be deprecated and replaced by SimpleITK? Is there anything I can help with?

I noticed the Wiki page (http://www.itk.org/Wiki/ITK/Wrapping) where it is said that ITK 4.7 will include support for Python 3 but will it also fix the problem with Clang or new Visual Studios?

I have to admit that I haven't tried SimpleITK so I don't know whether it could provide the same flexibility as wrapITK and how much of ITK related code would need to be rewritten.

Cheers,
Lassi
