[Insight-users] Problem with PolylineMask2DImageFilter

[edoardo.belletti at alice.it]

Hi
I have a problem: I want to use PolylineMask2DImageFilter to set to zero all the pixel that are outside a PolyLineParametricPath that I defined as a closed line. 
But with PolylineMask2DImageFilter some pixel that are inside my closed line are also set to zero and I don't know how to avoid this. 
I hope that you understand what I want to say.

Thank you for the help

Edoardo
