[Insight-users] Can I use ITK as a encapsulation function isolated outside of ITK?

[Luis Ibanez]

Hi Goo,

Yes you can encapsulate an ITK pipeline as an independent
function call.

You must however be careful regarding memory allocations
and release.


For a full list of details on how to encapsulate ITK in
functions please look at the Tutorials:

      http://www.itk.org/HTML/Tutorials.htm

In particular to

   "Getting Started V: Integrating ITK in your Application."
   http://www.itk.org/CourseWare/Training/GettingStarted-V.pdf


Examples of applications that encapsulate ITK pipelines as
functions can be found in:


     InsightApplications/VolviewPlugins


About the link problem that you are finding with ITKFilterLib,
it is probably du to mixing compilation modes between your
build process for the library and the build process for the
application that uses the library.


Typical mistakes are:

1) build the library as Debug, and the application as Release
2) build the library as Release and the application as Debug


Visual Studio probably already warned you about the mixing
of those libraries. Many people make the mistake of ignoring
the warning and forcing Visual Studio to mix the libraries.


Please make sure that you use the *exact same* compilation
modes for all the components of your applicaions.



   Regards,


      Luis
