Thank you so much, this is excellent, and exactly the sort of thing I have
been looking for, for several weeks!

This macro command, getResult(); detailed here
http://rsb.info.nih.gov/ij/developer/macro/functions.html

how can I run it and get data from it from within a PluginFilter? My
experience knows only of the following:

IJ.runMacro("getResult()"); method detailed
http://rsb.info.nih.gov/ij/developer/api/ij/IJ.html returns a String, which
is the data from the macro. This is in my mind a little indirect but
accomplishes the desired goals -- is this the only way?

Thanks again so much :-D

-Mike
