first of all sorry for delay but it’s busy period at work…
The main difference is that you can debug easily your code taking the advantage of using an IDE.
Never tried but I presume no because you are using a jython interpreter and then you would like to use the jython plugin written in Eclipse in Fiji with jython.
yes you have to add it as external libraries in the pythonpath (see the 3rd point of the link I mentioned in my first reply), you can also add other apis from other Fiji plugins and setting the plugins.dir (see point 4 of the same link)
honestly I dont know this module but in principle you can import it and try to use it (adding it as an external libraries)
At least I think it can work, I will try to test it but as I was saying it’s a real busy period at work so I don’t know when I can report back to you…
Have a nice day,
