I posted similar questions last week but no luck - no response.

So I'll try to reformulate and simplify. This applies to macro programming :

1) how to store a "freeline" ROI in a variable = get the ROI coordinates
and store them in an array (problems : getting the coordinates, knowing
the size of the array needed)

2) if 1) is not possible, how to store it on a temporary file ?

3) related to this : how is a freeline ROI stored by the ROI manager ?
(if I open a saved freeline ROI with notepad, I get a cryptic string.
What does it mean ?)
