[vtkusers] Extracting and projecting isolines in a 2D image

[Thomas Deschamps]

Hi vtkUsers,

I have a 2D image, I would like to extract isolines from this image
(probably with vtkMarchingSquare)
And I would like to superimpose these isolines (probably vtkPolyData)
onto the 2D image where they lie.

Do you know how I can handle that?
Thank you for your help.
