Hi Philippe,
sorry, I can't reproduce the problem.
I tried the following in JavaScript interactive mode:
(the indented lines are the output)
r=new OvalRoi(1,2,3,4);
Roi[Oval, x=1, y=2, width=3, height=4]
p=r.getContainedPoints();
[Ljava.awt.Point;@3153ceb9
p.length
8
It also works with an oval roi created by hand on the 'blobs' sample,
and starting with
r=IJ.getImage().getRoi();
I also don't see anything suspicious in the getContainedPoints() code.
Michael
