A couple/several of issues about the ROI Manager
 
|
Dear all / Wayne,
Im contacting you again about a couple issues found within the ROI Manager which is a very powerful feature I really use a lot for my applications (actually for all of my applications). So here is the list of the found issues: - Macro recorder: the recorder isnt anymore saving the show_all and label fonctions of the ROI Manager - The fonction Update of the ROI Manager cant be used anymore: when you select a ROI in the ROI Manager, then select something else in the picture, the ROI in the ROI Manager gets deselected and thus it isnt anymore possible to update it. Im unfortunately almost sure that the ROI Manager behaves this way following a modification I already asked in a mail from the 30th October L I think what should be the best behavior of the ROI Manager concerning this issue is that it behaves similarly to how it was in the version 1.45s, where, when selecting a ROI in the ROI Manager it gets selected and by clicking again on it gets deselected, that is it - Restore selection: I guess this issue is more or less connected with the previous one and can be seen by putting a couple (lets say 3) ROIs in the ROI Manager, then make another selection with a selection tool in the picture, then reselect a ROI in the ROI manager (lets say the second one) and by restoring the selection (Shift + e) you are actually reselecting the last ROI in the ROI manager (i.e. the third one) and not the last manually draw ROI as expected. - Multiple selections in the ROI Manager: By selecting several ROIs within the ROI Manager, I would expect that all the selected ROIs are shown up in the picture, but only the first selected one can be seen. I thank you very much for your feedback and/or answer on this issues.

The ROI Manager’s “Update” command still works. You can move, resize, add to (by holding down shift key) or subtract from (by holding down alt key) an ROI, click “Update” and the ROI will be updated. What you can no longer do is use “Update” to replace an ROI in the ROI Manager with another ROI, but why would you need to do that? > I'm unfortunately almost sure that the ROI Manager behaves this way > following a modification I already asked in a mail from the 30th October L > > I think what should be the best behavior of the ROI Manager concerning this > issue is that it behaves similarly to how it was in the version 1.45s, > where, when selecting a ROI in the ROI Manager it gets selected and by > clicking again on it gets deselected, that is it. > > - Restore selection: I guess this issue is more or less connected > with the previous one and can be seen by putting a couple (let's say 3) ROIs > in the ROI Manager, then make another selection with a selection tool in the > picture, then reselect a ROI in the ROI manager (let's say the second one) > and by restoring the selection (Shift + e) you are actually reselecting the > last ROI in the ROI manager (i.e. the third one) and not the last manually > draw ROI as expected.

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. >> - Multiple selections in the ROI Manager: By selecting several ROIs >> within the ROI Manager, I would expect that all the selected ROIs are >> shown up in the picture, but only the first selected one can be seen. > Only the first ROI is shown because, except in an overlay, ImageJ can only display one ROI at a time. 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 -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |

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.

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...

Salut Philippe.
The following javascript transiently displays rois that are selected in the Roi manager. Maybe you could use something like this. Sincerely, Jerome imp = IJ.getImage(); rm=RoiManager.getInstance(); rm.runCommand("Show None"); si=rm.getSelectedIndexes(); overlay = new Overlay(); for (i in si) { roi = rm.getRoi(si[i]); roi.setStrokeWidth(0.1); roi.setStrokeColor(Color.cyan); overlay.add(roi); } imp.setOverlay(overlay); IJ.wait(2000); overlay.clear(); imp.setOverlay(overlay); rm.runCommand("Show All"); On 18 February 2015 at 14:58, Philippe CARL <[hidden email]> wrote: > > 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 ;

Salut Jérôme,
How are you doing? What's new? I thank you very much for your code which is indeed giving an excellent solution for the discussed issue, especially when associated to an hotkey to easily launch it. For the users of the list who would as well be interested by using your code within Fiji (sorry about that) I had to slightly modify your code (so that it is working) in the following way: importClass(Packages.ij.IJ); importClass(Packages.ij.plugin.frame.RoiManager); importClass(Packages.ij.gui.Overlay); importClass(Packages.java.awt.Color); imp = IJ.getImage(); rm = RoiManager.getInstance(); rm.runCommand("Show None"); si = rm.getSelectedIndexes(); overlay = new Overlay(); for(i in si) { roi = rm.getRoi(si[i]); // roi.setStrokeWidth(0.1); // roi.setStrokeColor(Color.green); overlay.add(roi); } imp.setOverlay(overlay); IJ.wait(2000); overlay.clear(); imp.setOverlay(overlay); rm.runCommand("Show All"); Also and especially, from your code I discovered the instruction "for(i in si)" which I didn't know (since then I looked of course for all the alternative options available for using the "for" instruction) and able me now to modify (= simplify) other code I have (and that was written by using the traditional way of the "for" instruction).

The following JavaScript code highlights selected ROIs in “Show All” mode. Selected ROIs are drawn in cyan with a stroke width of 2 and all others are drawn in the default ROI color and stroke width. This code requires the latest daily build, which adds the RoiManager.isSelected() method. -wayne rm = RoiManager.getInstance(); for (i=0; i<rm.getCount(); i++) { roi = rm.getRoi(i); if (rm.isSelected(i)) { roi.setStrokeWidth(2); roi.setStrokeColor(Color.cyan); } else { roi.setStrokeWidth(0); roi.setStrokeColor(Roi.getColor()); } } rm.runCommand("Show All"); -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |
