Check if command is finished in a macro

[Djoere Gaublomme]

Hi all,

I was wondering if it is possible to check whether a function has  
finished in a macro, in order to avoid the next command being  
initiated too early.

I have read the following:  
http://imagej.1557.x6.nabble.com/Is-it-normal-to-use-a-wait-instruction-after-a-command-td5011551.html , and applied the proposed solution therein for functions that produce a new image window as  
output.
For example:

while (!isOpen("Resulting-Image")) {
wait(100);
}

However, I would also like to be able to check if filters that don't  
produce a new image window, such as the "Gaussian Blur 3D", were  
executed completely.

Is there a trick that allows you to do this?
Or is it necessary to change the plugin to allow for this?  Would that  
be a hard thing to do (I am only familiar with macros)?

Thanks in advance for any ideas!

Hi Djoere,

I believe this is the purpose of the IJ.macroRunning[1] method.

Instead of using wait(100), your while loop would look like this:

while (IJ.macroRunning() {
// Nothing needed here. Just wait for macro to end.
}

Hope that helps.

Best,
Mark

Hi Mark,

Thank you for your answer.

I am afraid I am going to need some handholding, as I am unfamiliar  
with IJ methods.
Is this usable in a normal ImageJ macro?  Or only in a plugin?

When I try to run it in a macro, I get the error "Unrecognized IJ  
function name".
Is there a need to somehow import this method?

Kind regards

Djoere

PS: I assume there should be an extra parenthesis? --> while  
(IJ.macroRunning()) {

Macro functions, including "Gaussian Blur 3D”, do not return before they are finished except for a few external plugins, such as ""LoG 3D”. Please provide example macro code that does not work as expected without wait() calls.
