[Insight-users] Polyline input of itkPolylineMask2DImageFilter

[Zhu, Yaoyao (NIH/NLM/LHC) [C]]

Hi, Andinet and all,

I checked the CVS directory for the updated
itkPolylineMask2DImageFilter. It looks like that the file has been
modified back and forth. My question is 

What kind of contour this filter takes in? If it is "
itkPolyLineParametricPath". The vertex inside is "ContinuousIndex"
instead of physical points.

Can anyone have used this filter before? Please let me know how to input
the contour?

Thanks a lot,

yaoyao

Hi Yaoyao,

Thanks for pointing out the redundant transformation.

I have committed a fix to CVS. Please give it a try and
let me know if you see any other issues
