Dear ImageJ list,


I am trying to get the coordinates of the centroid of my ROI, which is in my case a polygon roi I think. I can see the centroid coordinates by using the Analyzer but I need to call this from my plugin.


I tried like this:

Roi roi = image.getRoi();
ImageStatistics stats = roi.getImage().getStatistics();
System.out.println("(" + stats.xCentroid + " : " + stats.yCentroid + ")");


But at the moment I will get an output (0.0 : 0.0) which I don't understand.

Can you help me here?


Thank you,

Maximilian
