scrollable zoom

[Leon Espinosa]

Hello I have modified the plugin scrollable-stackwindow (by Johannes  
Schindlin) to have a mouse wheel control of the current image/stack...

//---------------------------------------------

import ij.IJ;
import ij.ImagePlus;
import ij.gui.ImageCanvas;
import ij.gui.StackWindow;
import ij.plugin.PlugIn;
import ij.plugin.*;

import java.awt.event.MouseWheelListener;
import java.awt.event.MouseWheelEvent;

public class Scrollable_Zoom implements PlugIn {
        public void run(String arg) {
                ImagePlus image = IJ.getImage();
                image.setWindow(new Window(image, image.getCanvas()));
        }

        static class Window extends StackWindow implements MouseWheelListener {
                public Window(ImagePlus image, ImageCanvas canvas) {
                        super(image, canvas);
                        addMouseWheelListener(this);
                }

                public void mouseWheelMoved(MouseWheelEvent event) {
                        synchronized(this) {
                                int zoom = event.getWheelRotation();
                                if (zoom<0) IJ.run("In");
                                else IJ.run("Out");
                        }
                }
        }
}

//---------------------------------------------------------


Save it as Scrollable_Zoom.java and use "compile and run..." command.
