Dear Rabih,
You can find all the macro instructions under the following link:
http://rsb.info.nih.gov/ij/developer/macro/functions.htmlAnd the instruction Roi.getBounds(x, y, width, height) "returns the location
and size of the selection's bounding rectangle".
Thus you can find the coordinates of points on the boundaries of the ROI by
checking either with Roi.contains(x, y) or selectionContains(x, y)
(selectionContains(x, y) being a Boolean it may be a better choice) whether
a point of the pointing rectangle is part of the ROI. You will at least find
4 points agreeing this condition and in the case the ROI is already a
rectangle, all the bounding rectangle will agree your request.
Best regards,
Philippe
