Hi all-
I am going through the ImageJ guide in a systematic way as a beginner and
came across unexpected behavior. If I have multiple selections in the ROI
manager and then select More->AND (or OR or XOR), no new ROI with the newly
combined ROI appears (let's call it ROI XOR). If I hit update, then the ROI
at the top of the list of ROI's I had selected is replaced by the new,
combined ROI XOR. But the only way I can get the ROI XOR to appear is by
updating it over one of the original ROI's. Further, if I have no ROI
selected, the ImageJ manual suggests all the ROI's will be used for the
AND/OR/XOR operation, but because I don't then have a specific ROI
highlighted, when I click update, nothing happens (understandably, since I
haven't highlighted an ROI), which means the new ROI XOR doesn't appear. Is
this expected behavior? The way the manual reads, I was expecting the new
ROI XOR to appear as a new ROI in the ROI manager, but it doesn't.
I'm using Fiji with ImageJ 1.50b, running on Windows (32 bit - my old
crappy laptop).
Thanks for the insight
-Jason
