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
