Return value to macro from java plugin

[jumpfunky]

Hi,

it is possible to return a value from an imagej java plugin to an imagej
macro?

I've written an imagej plugin which estimates the noise sigma from a
single image. What I want to do inside the macro is:

sigma = MyNoiseEstimationPlugin();

Is that possible?

Cheers,
Thorsten

You can  set a 'property' to the image that you are processing from a plugin
or macro and then get that property from another macro:

you might also consider using JavaScript instead of the ImageJ Macro
Language in such a case. It's still pretty simple and straightforward,
and can even be generated by the ImageJ Macro Recorder.

Hi Thorsten,

one more possibility: you can return a String value in a static method of
the macro:

result = call("myClass.myMethod", arg1, arg2, ...);

Your plugin (here 'myClass.java') should have a method
    public static myMethod(String arg1, String arg2, ...)

Of course, the Strings may be also numbers converted to Strings.
