[Insight-users] a bug in ImportImageFilter?

[Miller, James V (Research)]

This might be a naming/doc issue.  Here "Source" refers to the
ImportImageFilter.
It is considered a "source" since it produces output but doesn't take an
input
in the tradition pipeline sense. "Source" is the generic name of an object
that 
produces output.  This is in contrast to a "filter".

"Source" does not mean your application rather it means the
ImportImageFilter.
