[ImageJ-devel] loading imageJ instance with full Services

[Johannes Schindelin]

Hi Mohamed,

to avoid making me feel like a commodity, please keep the list in Cc:.
This helps other people having the same question, and myself not having to
answer the same question multiple times. It also keeps an open
communication, a crucial part of what science is all about.

That is correct. You have to ask the UIService to show the user interface.
Otherwise, truly headless operation would be impossible! And that was an
express goal of ImageJ2: to be modular enough so as to make it as useful
as possible.

As I said, ij.ui().showUI() should do it.
