[Insight-developers] proposal: enhancing wrapitk's filter coverage during (one of) the next tcon

[Gaëtan Lehmann]

Hi,

You may know that WrapITK has greatly enhanced the filter coverage,  
compared to what was previously available in tcl, java and python.  
Currently, 66% of the filters in ITK are usable in WrapITK. In the  
future, the goal is to reach 100% of filter coverage. This is a quite  
difficult task for a single person, because it requires a quite good  
knowledge of the whole ITK, to be able to select, for all the classes,  
the relevant template parameters to instantiate. I made my best to  
complete this task, but obviously, I can't go further, because I'm not  
able to make a decision on the remaining non wrapped filters.

I think that the weekly tcon can be a great place to select the  
template parameters needed to instantiate the missing filters in  
WrapITK. For many of the filters, I'm quite sure the right template  
parameters to use are obvious for many of us, and that they only need  
to be collected. With those data, I would be able to implement the  
wrappers and to add them in WrapITK.
Also, some of the filters may not be of direct interest for the user,  
because they are intended to be used only internally in some other  
code, or because they can only be used as a superclass (like  
UnaryFunctorImageFilter). In that case, they should be added in the  
excluded filters list for the filter coverage.

A good goal, for the next release, would be to cover 80% of ITK's  
filter, which means 51 new filters added in WrapITK or in the excluded  
filters list. 51 filters may look like a big number of classes (and it  
is, for the final python/tcl/java user), but many of the remaining  
filters seems similar, so it should be easy to choose the template  
parameters for a group of filters, instead of processing them one by  
one.

Also, note that adding new stuff in WrapITK would not only benefit to  
WrapITK users: because building a class in WrapITK builds every  
methods in that class, we have found many bugs in ITK code during the  
addition of new classes in WrapITK in the past. It is likely that we  
would uncover a few more bugs by adding new classes, bugs which won't  
be found by final users.

A list of unwrapped filters can be found at the end of this mail.

What do you think?
