(Java) How to save an ImageStack

[Robert Lockwood]

I've created and populated an ImageStack in my Java app, how do I save the
stack?

outRGBStack = ImageStack.create(NCOLS, NROWS, NSLICES, 24);

Here is JavaScript example that creates a stack, saves it in the temp folder, re-opens it, and displays it:

  NCOLS = NROWS = NSLICES = 256;
  PATH = IJ.getDir("temp")+"RGB_Stack.tif";
  rgbStack = ImageStack.create(NCOLS, NROWS, NSLICES, 24);
  img = new ImagePlus("RGB Stack",rgbStack);
  IJ.saveAs(img, "tif", PATH);
  img = IJ.open(PATH);
  img.show();

Dear Robert, for Wayne I just present my best greetings since I would be
incredibly pretentious to think to teach you something within ImageJ :)
The ImageJ PLugins>Macros>Record... tool can as well be configured to record
Java code by changing the selection of the drop down menu on the top left of
the recording window from macro to Java.
And thus by opening "manually" a stack and saving it you can then easily
figure out the needed code.
My best regards,
Philippe

folder, re-opens it, and displays it:

  NCOLS = NROWS = NSLICES = 256;
  PATH = IJ.getDir("temp")+"RGB_Stack.tif";
  rgbStack = ImageStack.create(NCOLS, NROWS, NSLICES, 24);
  img = new ImagePlus("RGB Stack",rgbStack);
  IJ.saveAs(img, "tif", PATH);
  img = IJ.open(PATH);
  img.show();

Hi Phillippe

The macro recorder (that also record Java code) is wonderful, but in
this case Wayne provided an important item that does not show in the
recorder. The IJ.save method  requires an ImagePlus , and when you
create a new stack you need to get an ImagePlus with that stack, and
Wayne does this with the line

img = new ImagePlus("RGB Stack",rgbStack);

The recorder does not show this step --it creates a stack with
IJ.createImage which returns the ImagePlus directly.

So while the macro recorder is wonderful, and i use it a lot, sometimes
you need to dig a bit to figure out how to use the API to do something.

Best regards

Dear Aryeh,
I don't really know whether and / or how I should answer your mail or not.
As I wrote it, I really don't believe (or even try) to teach something to Wayne (even knowing that I'm French and thus probably very pretentious by nature).
I just wanted to point out that the ImageJ recorder (even it is found within the menu Plugins>Macros>Record...) is not only able to save macro code, but can as well be configurated for generating java code which is quite helpful and often doing the needed job.
And as far as I'm concerned, I didn't know (or took attention of) this option for a long time and since I know it, it is helping me out a lot.
Thus I just wanted to share this information for the readers who never took attention on this point, that was the reason of my post, nothing more...
Have a nice day,
Philippe

Thanks for the heads up that I can record as Java!
