Hi Dscho,

thanx a lot, I was somehow aware of the "Socket listener" in ImageJ, but
from the docs
that I had see had the impression that it´s only used or useful to
synchronize multiple ImageJ
instances, not for sending commands. GREAT, I´currently taking a look at
the source code.

At that would be missing for my planned task would be a simple (C?)
frontend that can
be compiled into a standlaone exe that sends commands (maybe given as its
command line
args) to that socket.

I will start to make one if there is nothing already available.

Cheers

Joachim

ImageJ optionally runs with a socket listener (in Fiji, it is on by
default, but it is not the regular socket listener, but an RMI-based one,
so it is safe enough).

With such a socket listener, starting ImageJ again with command line
options (such as -eval <commands>) will send the commands to the existing
instance.

Hth,
Dscho
