After that, I found this thread. I tried the suggested code snippet (using CAP_ROUND and JOIN_ROUND), and it almost works. However, the area I get when I create the stroked shape has holes in it other than the original shape. Can you explain this?
The holes should be smaller than the original shape--by half the stroke width. You have to union the stroked shape with the original shape to eliminate the holes: Area expanded = new Area(stroke.createStrokedShape(shape)); expanded.add(new Area(shape)); I've attached a demo that will write out "expand.png" (sorry, went overboard).
Also, how would you go about finding the outermost shape in the region? I don't think you can rely on comparing the results of the getBounds() functions; I thought that there was no guarantee on how closely the bounds will fit.
FWIW getBounds2D would probably be a better method to use. In practice I think the bounds are calculated by determining the bounds of all control points, so shape with some crazy beziers could potentially exceed the bounds. However presumably the two "contour" paths in a stroked shape would act similarly, so it probably isn't a big deal. I agree it's not foolproof though.
My solution was to calculate the area of the different subshapes and choose the one with the largest area.
Seems like that should work too. There is a pretty simple algorithm for calculating the area of a polygon, and you can use a flattening path iterator on an arbitrary shape.
