Dear ImageJ,
I have a question related to drawing an ROI. Following are the steps involved.
1. Open a DICOM image by drag and drop into ImageJ .
2. Create a rectangular ROI.
3. Use 'Shift' key and add another rectangular ROI. I see 2 rectangular ROIs now.
4. Now with 'Shift' key held, click on the image (just click and release the mouse button without drawing any area) --> The previously defined ROI disappears. Why is this happening? I thought that they should still be visible.
5. Now again I simply draw a rectangular ROI again (without shift key), and now along with the newly created ROI, the previously defined ROI re-appears.
Is this the working behaviour of ImageJ? It is bit confusing since at step 5, the previously defined ROI's also re-appear.. The issue is same when I use 'Alt' key.
Kindly let me know if this is considered a bug or this is the expected behaviour.
thanks,
Vidya
