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");
