[Insight-developers] Wrapping more ITK filters

[Gaëtan Lehmann]

Hi,

WrapITK has been moved to ITK last week, and thing seems to work quite  
well :-)
With WrapITK, I have tried to increase the number of filters available in  
the target languages. I created as much wrappers as I can, but I'm now  
stopped by the lack of knownledge about some of them. Here is the list  
given by the script filterCoverage.py, with ITK cvs:

315 filters
210 wrapped filters
105 non wrapped filters
66.666667% covered

I think that 66 percent of coverage is not so bad, but I would like to  
increase this value as much as possible.
Currently, it's not possible to reach 100% because of some limitations of  
cableswig with nested name space, but it should be possible to go up to  
~90%.

Please help to choose the useful sets of template parameters for the  
classes listed above.

The type of information needed is, for all the template parameters:
It must be an image ?
  - with integral pixel type ?
  - with real pixel type ?
  - with signed pixel type ?
  - with scalar pixel type ?
  - with vector pixel type ?
  - with covariant vector pixel type ?
  - with RGB pixel type ?
  - with complex pixel type ?
It must be something else than an image ? Which type ?

Also perhaps some filters are useful only for internal use in other  
filters, or as the superclass with a specific template parameter (like  
UnaryFunctorImageFilter) - just tell it to me, so I can exclude them from  
the list.

Thanks !

Gaetan
