calling macros from plugins

[chepe santacruz]

hello,

Is there a way to use/call  macros (built-in or user defined) in my ImageJ
plugins?

thanks for your help,

Hi,

Simply as :

IJ.run("Run... ", "run=..../mymacro.txt");

You can call a macro inline using IJ.runMacro():

       String macro = "angle = getArgument();"+
           "getRawStatistics(area, mean);"+
           "setBackgroundColor(mean, mean, mean);"+
           "run('Arbitrarily...', 'interpolate fill angle='+angle);";
       double angle = 15;
       IJ.runMacro(macro, ""+angle);

Or call a macro located in the macros folder using IJ.runMacroFile():

       // run the Polygon.txt macro in ..ImageJ/macros
       IJ.runMacroFile("Polygon", "argument");

Dear all,

I use to manage well things when doing macros, but I am completely lost when
I have to work with plugins. So I'll appreciate some help.

I would like to calculate the median of an array in a plugin, and I haven't
found a way to do it by browsing through the stored messages posted in the
mailing list. Can anyone tell me how to calculate the median of an array in
a plugin. Thanks a lot.

Sort the array of n elements, then
take the middle value if n=odd
take the average of the 2 middle values if n=even

Cheers,

Ok, that is the way to calculate the median of an array, I know that. I was
wondering if there is a command to do it automatically without programming
the whole process you have described. But thanks anyhow for your help.
That's how I'll proceed if I can't find a "shortcut".

It's a general programming question, not image specific, so its not
likely to be in the imageJ library. However, you can almost certainly
find open source sorting code you could borrow :)
If you're dealing with a reasonably small array, I'd use selection sort
or insertion sort (google will give you lots of info on either) because
they are both simple and easy to understand.
If you have to sort arrays frequently or the arrays are pretty large (in
the hundreds of items or more), it might be worth looking up a faster
algorithm. Quick sort is the best, in general, and doesn't require much
code, but the algorithm is a nightmare to understand at first. It's also
massively recursive.
Hope this helps!
