It depends on the performance you are looking for. One situation where
Area can take a fairly long time to perform its calculations is when you
have curves that are very similar to each other - which would happen
here if you had an "expand distance" that was very small - say much
smaller than a pixel. But I'm imagining that the expand distances will
typically be larger than a pixel so the calculations should be reasonable.
Try it and see (and report back on the results)...

Thanks. Actually I forgot to mention that I previously had used Area
but had some issues with performance. It seems like a bit of overkill
for this problem, since the path of interest is already calculated as
part of stroking. But I doubt there is a better solution unless I
reimplement part of BasicStroke, which I'm not going to do :-)
Thanks again,
Chris
p.s. This is for http://tonicsystems.com/products/viewer/ a free
PowerPoint viewer which uses Java2D *very* heavily. Expanding a shape
is necessary for shadowed+filled shapes with complex strokes (e.g.
dashed or triple-line)--the cast shadow is as if the shape had a solid
stroke. I assume MSFT did it that way because it was easier to
implement, which made me think there might be some tricky fast way.

You can use the Area class to add in the original Shape:
