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
