How to call Z-functions from a plugin on ImageJ

[Danae]

Good morning

I'm currently doing a plugin on JAVA for imagej that needs to call the function "Maximum Intensity Z-projection" which I know it's already in imagej if you go for "Image/Stacks/Z Project...".
Documentation here: Maximum Intensity Z-projection

I tried to call it like if I was running a plugin from another plugin but it didn't work (now I'm showing you the code I'm trying)

public class MaximumIntensity_ implements PlugIn{
        ImagePlus img = WindowManager.getCurrentImage();

        @Override
        public void run(String arg0) {
                // TODO Auto-generated method stub
                Object zProjector = null;
                zProjector = IJ.runPlugIn(img , "ZProjector", arg0);
               
                if(zProjector==null){
                        String arg = "Error";
                        IJ.showMessage(arg);

                }
        }
}

Thank you so much.

You can find this out by using the macro recorder.
Choose "java" for the target language in the recorder window.
In you case what you are after is:

IJ.run(imp, "Z Project...", "projection=[Max Intensity]");

There might be another way of doing, like calling the code directly, but the
above would do too.

Thank you so much :)
It worked perfectly.
I've just started to programme for imagej and I don't know a lot of things ^^
