Groovy plugin

Currently i'm working on a Groovy implementation

http://groovy.codehaus.org/

and i found out that Groovy comes with a nice editor which works very well
with ImageJ.

Here is the huge source:


import ij.plugin.*;
import groovy.ui.Console;

public class Groovy_ implements PlugIn {

    public void run(String arg) {
       
                new Console().run();
         
    }
}


To run the plugin simply download Groovy 1.5.7 at:
http://groovy.codehaus.org/Download
and copy the *.jar in the embeddable folder (groovy-all-1.5.7.jar) to your ImageJ plugins directory
as well as the attached compiled *.class files available by means of the Nabble forum.

Groovy_.class

Since Groovy is very close to *.java here is a first example in Java style (i'm just
beginning to learn groovy script!) which you can
interpret in the groovy editor.

import ij.*;
import ij.process.*;
import ij.gui.*;
import java.awt.*;
import java.util.Random;
import ij.plugin.*;

public class Random_Ovals implements PlugIn {

        public void run(String arg) {
                IJ.run("New...", "name='Random Ovals' type='32-bit RGB' width=400 height=400");
                if (IJ.altKeyDown())
                        drawOvalsFaster();
                else
                        drawOvals();
        }

        void drawOvals() {
                ImagePlus imp = WindowManager.getCurrentImage();
                Random ran = new Random();
                int width = imp.getWidth();
                int height = imp.getHeight();
                for (int i=0; i<1000; i++) {
                        int w = (int)(ran.nextDouble()*width/2+1);
                        int h = (int)(ran.nextDouble()*width/2+1);
                        int x = (int)(ran.nextDouble()*width-w/2);
                        int y = (int)(ran.nextDouble()*height-h/2);
                        IJ.setForegroundColor((int)(ran.nextDouble()*255),
                                 (int)(ran.nextDouble()*255), (int)(ran.nextDouble()*255));
                        IJ.makeOval(x, y, w, h);
                        IJ.run("Fill");
                }
        }

        void drawOvalsFaster() {
                ImagePlus imp = WindowManager.getCurrentImage();
                Random ran = new Random();
                int width = imp.getWidth();
                int height = imp.getHeight();
                ImageProcessor ip = imp.getProcessor();
                for (int i=0; i<1000; i++) {
                        int w = (int)(ran.nextDouble()*width/2+1);
                        int h = (int)(ran.nextDouble()*width/2+1);
                        int x = (int)(ran.nextDouble()*width-w/2);
                        int y = (int)(ran.nextDouble()*height-h/2);
                        ip.setColor(new Color((int)(ran.nextDouble()*255),
                                 (int)(ran.nextDouble()*255), (int)(ran.nextDouble()*255)));
                        Roi roi=new OvalRoi(x, y, w, h, null);
                        ip.setMask(roi.getMask());
                        ip.setRoi(roi.getBoundingRect());
                        ip.fill(ip.getMask());
                        if (i%10==0)
                                imp.updateAndDraw();
                }
        }

}

Random_Ovals ov=new Random_Ovals();
ov.run(null);



With kind regards
