Hi Robert,
another approach which might solve your problems is to have a "wrapper
library". Small .cxx file which defines some function such as void
smooth(short *imageBuffer, int xSize, ySize, zSize, spacing etc). This
function would then use import image
<http://www.itk.org/Doxygen/html/classitk_1_1ImportImageFilter.html> filter
to construct itk::image from its parameters. Then normally call itk
filters. Once you have the results, copy its pixel buffer into imageBuffer
or some other pointer passed as a parameter. You link this library to itk
which was configured with BUILD_SHARED_LIBS OFF. You should be able to
compile this library as either shared or static.
Then your main program would only need one function prototype (void
smooth(...);) and one wrapper library to link against. It would not
explicitly depend on itk (because it was linked in statically by the
wrapper library).
HTH,
Dženan
