returning results of plugins within macros

[Frederic V. Hessman]

I looked at the documentation, but I can't find a way of using the non-
image result of a plugin in a macro.

I want to be able to pull an entry out of a FITS image header and use  
it in a macro, something like

        exposuretime=run("Read FITS Header","image=[] key=[EXPTIME]");

Any ideas?  An alternative would be to be able to use Prefs within a  
macro, e.g.

        run("Read FITS Header", "key=EXPTIME");
        exposuretime=Prefs.get("fits.result");

This functionality would come in handy for other reasons.

Hello,

I think you want the macro command call("class.method", arg1,  
arg2, ...) See http://rsb.info.nih.gov/ij/developer/macro/ 
functions.html#C for more info.  The run("command", ...) command is  
used to call ImageJ menu commands which is a little different. Your  
FITS reader plugin will have to have a static method to return the  
contents of the FITS header as a string (or strings that have been  
concetenated into one string) to the macro.

Cheers,
Ben

Ah yes - I forgot "call".

Using 1.38x and the following method of my FitsJ class

                public static String getCardValueFromFile (String key, String  
image)

in a package located in the jar

                plugins/astroj.jar

and invoking call via the macro

                title = getTitle();
                exptime = call("FitsJ.getCardValueFromFile","EXPTIME",title);

I get an error message sayting that ImageJ can't find the FitsJ class,  
a problem normal plugins don't have.   Even tried renaming the jar to  
astroj_.jar......

OK - only works for plugins.  Got it....   I had wanted to avoid using  
an otherwise not so interesting plugin, but hey!, at least it works!
