[Insight-users] Using a ParametricPath

[Brady McCary]

insight-users,

I would like to know how to do the following.

Given

1. an input image,
2. an input parametric path

traverse all pixels that

1. the path goes through,
2. are one pixel to left
3. or one pixel to the right

and be able to distinguish left and right.

I believe that ExtractOrthogonalSwath2DImageFilter is close to what I
want, but I am not sure. I viewed the source and image result of
ExtractOrthogonalSwath2DImageFilterTest in Testing/, but I think I
need a few pointers.

Thanks for any input.

Brady
