Dear Romain,
As you pointed it correctly out, The macro instruction "roiManager("select",
indexes)" with "indexes" being an array of integers between 0 and
"roiManager("count")" is indeed doing the required job...
The "only" problem is to know WHAT you are putting within this "indexes"
array...
So I want (or rather need) to manually build up this array given certain
conditions (intensity [or evolution of the intensity on a time lapse] of the
pixels within a given ROI ; x, y position of a given ROI ; ...)...
And up to now it is not possible to see the newly added ROI in a selection
within the ROI Manager but only the first selected ROI.
What would actually be perfect is to have all the selected ROIs within the
ROI Manager displayed in the same way than in the "Show All" feature and the
last selected or added ROI within the selection as being highlighted.
But even without the last added ROI within the selection being highlighted,
I would already be extremely happy...
Bonne fin de journée,
Philippe

Hi Philippe,
I don't know if I understood correctly what you're looking for but did you
try the function :
roiManager("select", indexes)
Selects multiple items in the ROI Manager list, where indexes is an array of
integers, each of which must be greater than or equal to 0 and less than the
value returned by roiManager("count").
The selected ROIs are not highlighted in the ROI Manager list and are no
longer selected after the next ROI Manager command is executed.
Cheers,
Romain

Dear Wayne,
I thank you very much for your updates which are already improving a lot the
ROI Manager tool.
I would just have two comments on these updates:
>> - Macro recorder: the recorder isn't anymore saving the show_all
>> and label fonctions of the ROI Manager
> This regression is fixed in the latest ImageJ daily build (1.49p13).
"roiManager("Show All");" is recorded the first time you press the "Show
All" CheckBox, but after that it is not recorded anymore, as
"roiManager("Show None");" is correctly recorded each time you deselect the
"Show All" CheckBox.
In the same way "roiManager("Show All with labels");" is correctly recorded
as "roiManager("Show All without labels");" isn't recorded each time you
press the "Labels" CheckBox.

Up to now in ImageJ it is possible to simultaneously display all the ROIs in
the ROI Manager with the "Show All" feature together (= simultaneously) with
a selection and a ROI.
Now let's say you have a couple hundred of ROIs within the ROI Manager, and
you want then select several tens of them is order to apply a logical
combination (OR, XOR, AND)...
Today this is a quite difficult task unless of course there is an easy
solution that I may be missing.
What I'm thinking about is a code similar to what is running behind the
"Show All" feature as soon as you select more than a ROI within the ROI
Manager.
Only the first ROI is drawn as up selection, but behind you see all the
other selected ones and this selection is of course as well ignored in the
case the "Show All" CheckBox is set to "true".
I thank you very much in advance for your answer and work on this.
Have a nice day,
Philippe
