ROI Manager, multiple visible and editable selections

[ArtemisUser]

Hi,

I'm writing a plugin for ImageJ with Java and my goal is it to create multiple ROIs on top of an Image and they are supposed to be visible and editable. For that I'm looking for a way to activate the checkboxes "Show All" and "Labels" inside the ROI Manager.

If anyone has any tips or ideas that would be great. cheers

Hi ArtemisUser,

Have you considered using overlays?

Hi Curtis,

I have not much experience working with ImageJ, so you are probably right. I tried to add add Overlay like this:

oLay.add(new Roi(50, 50, 120, 120));
oLay.add(new Roi(200, 150, 120, 120));
imgp.setOverlay(oLayer);
imgp.updateAndDraw();

but then I can't move them arround and change their size (except if I  go to Imgae -> Overlay -> To ROI Manager)

Any advise for that?

Thanks

You can activate an ROI in an overlay by long pressing on it or by clicking on its label. Here is a JavaScript example.

-wayne

  img = IJ.createImage("Untitled", "8-bit black", 500, 500, 1);
  overlay = new Overlay();
  overlay.add(new Roi(50, 50, 120, 120));
  overlay.add(new Roi(250, 150, 120, 120));
  font = new Font("SansSerif", Font.PLAIN, 24);
  msg = "To activate a selection, long\npress on it or click on its label."
  text = new TextRoi(50, 350, msg, font);
  text.setStrokeColor(Color.white);
  overlay.add(text);
  overlay.drawLabels(true);
  img.setOverlay(overlay);
  img.show();
