RoiManager check box "Show all"

[Yuekan Jiao-2]

Hi

I have some ImageJ plugin code that uses ParticleAnalyzer and
RoiManager. What it does is to apply the ParticleAnalyzer on a binary
image impMask that is not shown, and the outlined Rois are transferred
to the RoiManager for consequent analysis. The problem came to me is
the “Show all” check box, it is unchecked in the previous versions (I
have used 1.45s, 1.46m), but it is checked in the recent versions (I
tested 1.46r and 1.47a) that causes an error “"There are no images
open.” The piece of code is following:

        ResultsTable rt = new ResultsTable();
        ParticleAnalyzer pa = new
ParticleAnalyzer(ParticleAnalyzer.CLEAR_WORKSHEET
                | ParticleAnalyzer.RECORD_STARTS
                | ParticleAnalyzer.ADD_TO_MANAGER
                | ParticleAnalyzer.SHOW_MASKS
                | ParticleAnalyzer.SHOW_RESULTS,
                Measurements.AREA | Measurements.RECT,
                rt, 1, Long.MAX_VALUE, 0, 1);

        pa.setHideOutputImage(true);
        pa.analyze(impMask);
        roiManager = RoiManager.getInstance();
        impPaMask = pa.getOutputImage();
        ipPaMask = impPaMask.getProcessor();

How can I set the check box “Show all” unchecked by default when the
RoiManager pops out? Or there is an image open and the check box is
checked, how can I uncheck it in the code?

Thanks

Yuekan

Upgrade to the ImageJ 1.47b daily build. It does not display the "There are no images open" error message when "Show all" is checked in the ROI Manager and no images are open.

You can use

   rm = RoiManager.getInstance();
   if (rm!=null)
      rm.runCommand("show none");

to uncheck "Show all".
