Hi all,

I'm running ImageJ 1.39t on Mac OSX v.10.5.2.  I'm working with a 29MB,
8-bit, 5558x5558 pixel jpg image.  When I calculate the centroid of a
polygon (fairly circular, ~2800 pixels diameter) in the center of the image,
I get negative values for the centroid.  Is there a way to correct this?

I had this problem once before in 2006 with an old version of ImageJ.   At
the time, the solution was to upgrade to the latest version, but I have
checked and am now running a current version.  I would appreciate any
suggestions for dealing with this problem.  Thanks.
