[Insight-developers] Bug in itkShrinkImageFilter

[Bill Lorensen]

Hans,

The documentation for ShrinkImageFilter says that it does simple
subsampling. So it is not really a bug according to the documentation.
However, I think your implementation is more useful (I assume it is
correctly done). You should probably fix the documentation in the .h
file when you commit these changes.

Also, beware that we have enabled a KWStyle commit check for some
directories. These directories are Testing/Code/Review, Code/Review,
Code/IO and Code/BasicFilters. All of these directories are currently
clear of any style defects.
