Thanks for the answer, but this is not exactly what is needed. The point
is to get a *fixed size* area outside the contour in pixels, but not
in units of contour levels.

Imagine, there is a smooth image and I'm going to extract some region
oustide the contour. Since the gradient is negligible, operating with s
contour
level you can give a region of 1000.. pixels wide (depends on the
gradient) ...
