I would like to draw two circles
 
|
Hi,
I am trying to draw two circles - they are supposed to be one ROI. My problem is that the following code draws only one circle: IJ.makeOval(50, 50, 50, 50); IJ.setKeyDown(16); IJ.makeOval(50, 100, 50, 50); RoiManager rm = new RoiManager(); rm.addRoi(img.getRoi()); Is there a bug or am I doing something wrong? Thanks, Avital -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |

This works based on http://rsbweb.nih.gov/ij/macros/CompositeSelections.txt
makeOval(52, 35, 105, 108); setKeyDown("shift"); makeOval(126, 117, 129, 129); roiManager("Add"); ========================================================================= Michael Cammer, Microscopy Core & Skirball Institute, NYU Langone Medical Center Cell: 914-309-3270 Temporary location: SK2-7 http://ocs.med.nyu.edu/microscopy & http://microscopynotes.com/ -----Original Message----- From: ImageJ Interest Group [mailto:[hidden email]] On Behalf Of Avital Steinberg Sent: Wednesday, November 19, 2014 2:53 PM To: [hidden email] Subject: I would like to draw two circles Hi, I am trying to draw two circles - they are supposed to be one ROI.

Avital,
This page ( http://cmci.embl.de/documents/120206pyip_cooking/python_imagej_cookbook#associating_multiple_rois) by Kota Miura might help you. It is the Jython version, but you can see an "or" operator and the ShapeRoi class...

Hi Michael,
Thanks - I know that this works. In macros, I have no problems doing this. My problem is doing a very similar thing in a Java plugin, Avital On Wed, Nov 19, 2014 at 10:48 PM, Cammer, Michael < [hidden email]> wrote: > This works based on > http://rsbweb.nih.gov/ij/macros/CompositeSelections.txt > > > makeOval(52, 35, 105, 108); > setKeyDown("shift"); > makeOval(126, 117, 129, 129); > roiManager("Add"); > > ========================================================================= > Michael Cammer, Microscopy Core & Skirball Institute, NYU Langone Medical > Center > Cell: 914-309-3270 Temporary location: > SK2-7 > http://ocs.med.nyu.edu/microscopy & http://microscopynotes.com/ > > -----Original Message----- > From: ImageJ Interest Group [mailto:[hidden email]] On Behalf Of > Avital Steinberg > Sent: Wednesday, November 19, 2014 2:53 PM > To: [hidden email] > Subject: I would like to draw two circles > > Hi, > I am trying to draw two circles - they are supposed to be one ROI.

Hi Avital,
With the help of the command recorder in Java mode, I found that the following works, using the RoiManager class. RoiManager rm = new RoiManager(false); rm.addRoi(new OvalRoi(50, 50, 50, 50)); rm.addRoi(new OvalRoi(50, 100, 50, 50)); rm.setSelectedIndexes(new int[]{0,1}); rm.runCommand("Combine"); Jerome.

Hi John,
This is very useful to know, because it can be done also in Java: http://rsb.info.nih.gov/ij/developer/api/ij/gui/ShapeRoi.html#or%28ij.gui.ShapeRoi%29 Thank you, Avital On Wed, Nov 19, 2014 at 10:48 PM, John Minter <[hidden email]> wrote: > Avital, > > This page ( > > http://cmci.embl.de/documents/120206pyip_cooking/python_imagej_cookbook#associating_multiple_rois > ) > by Kota Miura might help you.
