I'm going over the excellent Beaker notebook. (thanks - @etarena and @ctrueden) It is very well written and the code works very nicely. I have a question about ImageJ Ops:
When I look for information about a certain Op:
(RandomAccessibleInterval out?) =
I understand the input argument, but I don't understand what the optional output argument means. If I use a RandomAccessibleInterval output argument, I guess it means that the function would return a RandomAccessibleInterval object. But what would happen if I would not give an output argument - what type of image would be returned then?
