int[] ( PointRoi )ImagePlus.getRoi().getXCoordinates();
int[] ( PointRoi )ImagePlus.getRoi().getYCoordinates();

http://rsb.info.nih.gov/ij/developer/api/ij/gui/PolygonRoi.html#getXCoordinates()

those are unfortunately relative to the bounding box of the Roi which
you can get by

( PointRoi )ImagePlus.getRoi().getBounds()

http://rsb.info.nih.gov/ij/developer/api/ij/gui/Roi.html#getBounds()

I am looking forward to writing the next line of your Plugin ;)

Best,
Stephan
