Apologies for the delay in reply. Just wanted to let you know that we are
not ignoring you -- the timing was just rough because we recently returned
from an intense hackathon (see https://github.com/imagej/imagej-ops if
interested) and are still catching up on the backlog. I will make an effort
to reply to your questions within the next few days.

> o may the command assume that its initializer, if any, has been executed
> prior to executing its run-Method?
> o may the initializer-Method assume some of the parameter of the command
> already set
> (as e.g. a single ImageDisplay), and of course, which parameters?
> as an example, the DuplicateImage command adds input parameters to
> in its initializer-method depending on the inputDisplay.
> Thus is seems that DuplicateImage requires, that inputDisplay is set

> parameters lateron.
> o more generally, are there parameters of commands set by the standard
> ij2 preprocessos

> And is there an easy way to figure out

> - What is your concept to run a headless command from command line (or
> shell script), which
> adds input parameters dependent on the value of other input parameters?
> Do you encourcage to dynamically add input parameters to commands?
> - Is there (still) a static method to get hold of the context, as a while

> possible via ImageJ.getContext() in order not to (very) often create a
> context (or it the context impemented as a singelton)?
> And how does this work out if running command "truely" headless that is
> from command line without ij2 GUI?
> - is it remnants, that some ContextCommands have services as parameters
> as they - if I understand correctly - could retrievee the services from
> their contex?
> - has ij2 already support to execute a headless command from the command
> line or shell script
> Thanks a lot and cheers
