[Insight-users] Problem with PolylineMask2DImageFilter

[Luis Ibanez]

Hi Edoardo,

There are a couple of cases that this filter
doesn't manage correctly.

Namely:

A)  non-convex polylines

B) Polylines for which two of its vertices will be
    mapped onto the same pixel of the image


You may want to check that your polyline+image
doesn't incur in either one of these cases.


It will be helpful if you post a screen shot of your
output image...


     Regards,


           Luis
