IJ.run("Abs", "stack")

[David Webster]

All,

I put this into some Java code that first creates a Stack and inserts it
into an ImagePlus object. but, say I had more than 1 Stack/ImagePlus combo,
how does IJ.run("Abs", "stack") know which stack to use?

Use the version of the run method that takes an ImagePlus object as an
argument, for example

     IJ.run(imp, "Abs", "stack");

-wayne

Wayne,

If I wanted to do this with a specific ImageProcessor or ImageStack object,
would I then just use appropriate object name?

Hi david,

I´m not sure what you refer to as "name"?!:

if you are talking of Java objects, imp is the "name" to the respective
ImagePlus here (or to be more exact, a variable that holds a reference to
it)

On the macro level, (which can also apply to Java "objects"), each image
(ImagePlus) has also a numerical id to identify it or you can search for
the "title" of the
"image" (which is not necessarily unique)

Also, in the case you do not specify any imp/id, there is always an
"active", resp. "current" or topmost image that IJ will use.

Cheers

Mit freundlichen Grüßen / Best regards

I think the problem I was having was that I migrqted my Java code from the
macro recorder and the macro documentation doesn'r show inputting an
ImagePlus object as an option. When I broke down and read the API
documentation, I saw that option.

Thanks to all
