I am a new user of ImageJ (version 1.53a on a Windows computer). I am using the multipoint tool to count ducks and classify them based on sex and age. I am trying to save a simple JPG of the finished image per my boss’s request, but every time I try all I get is the original photo with the grid I overlayed, no points at all. I tried “flattening”, but that appears to do nothing with the points (which I believe have to do with ROI?).
Another less serious, but annoying problem-- the undo/Ctrl-Z doesn’t seem to work for anything. This resulted in me counting 400 ducks twice over. What the heck am I doing wrong?!
