Freehand selections

[Blandine Chanteloup]

Hello,

Does anybody know the name of the macro or plugin or function called when
the mouse is pressed on the "Freehand selection" button in the ImageJ
toolbar ???

Please HELP    ....

Thanks

Still searching on that? I've given up. I'm not sure, but I don't think
anything happens when you press that button, what happens is described in
ImageCanvas. Though I've got to disappoint you on that, I've studied the
code, I've tried almost everything, but still nothing works.

Hello,
the only thing that happens when one of those buttons is pressed is that
the selected tool changes.
It depends on the selected tool what happens when you click on an image
afterwards.

Finally,

I've defined a FreehandRoiBis classe inherited from the FreehandRoi one
where the grow() method is public and not protected.
And here is my code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class JFrame_TestImageJROI extends javax.swing.JFrame
                 implements MouseListener, MouseMotionListener {
         private ij.IJ myImageJ;
         private ij.ImagePlus myImagePlus;
         private ij.process.ImageProcessor myImageProcessor;
         private ij.gui.ImageCanvas myImageCanvas;

         private FreehandRoiBis roi;

         int xOrigROI;
         int yOrigROI;

         public static void main(String[] args) {
                 JFrame_TestImageJROI inst = new JFrame_TestImageJROI();
                 inst.setVisible(true);
         }

         public JFrame_TestImageJROI() {
                 super();
                 initGUI();
         }

         private void initGUI() {
                 try {
                         setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
                         this.setFocusable(false);
                         pack();
                         setSize(400, 300);
                         myImageJ = new ij.IJ();
                         myImageJ.open("image.bmp");
                         myImagePlus = myImageJ.getImage();
                         myImageProcessor = myImagePlus.getProcessor();
                         myImageProcessor.setColor(Color.yellow);
                         myImageProcessor.setLineWidth(2);

                         myImageCanvas = new ij.gui.ImageCanvas(myImagePlus);
                         this.add(myImageCanvas);

                         myImageCanvas.addMouseListener(this);
                         myImageCanvas.addMouseMotionListener(this);

                 } catch (Exception e) {
                         e.printStackTrace();
                 }
         }
         public void mousePressed(MouseEvent evt) {
                 xOrigROI = evt.getX();
                 yOrigROI = evt.getY();
                 roi = new FreehandRoiBis(evt.getX(), evt.getY(), myImagePlus);
                 myImagePlus.setRoi(roi);
                 roi.drawPixels(myImageProcessor);
                 myImagePlus.setProcessor(null,myImageProcessor);
                 myImageCanvas.repaint();
         }
         public void mouseDragged(MouseEvent evt) {
                 roi.grow(evt.getX(), evt.getY());
                 roi.drawPixels(myImageProcessor);
                 myImagePlus.setProcessor(null,myImageProcessor);
                 myImageCanvas.repaint();
         }
         public void mouseReleased(MouseEvent evt) {
                 roi.grow(xOrigROI,yOrigROI);
                 roi.drawPixels(myImageProcessor);
                 myImagePlus.setProcessor(null,myImageProcessor);
                 myImageCanvas.repaint();
         }
         public void mouseClicked(MouseEvent evt) {}
         public void mouseExited(MouseEvent evt) {}
         public void mouseEntered(MouseEvent evt) {}
         public void mouseMoved(MouseEvent evt) {}
}

Thanks everybody and especially Volker

Would you mind sharing the code of FreehandRoiBis? I'm still having
difficulties ...
(e.g. for roi.drawPixels(myImageProcessor);  I'm getting a compiler error
(drawPixels() in ij.gui.Roi cannot be applied to
(ij.process.ImageProcessor)). Thanks a lot!

Here is the code of FreehandRoiBis :

import ij.*;
import ij.gui.*;

public class FreehandRoiBis extends FreehandRoi {

     public FreehandRoiBis(int x, int y, ImagePlus imp) {
         super(x, y, imp);
     }

     public void grow(int ox, int oy) {
         super.grow(ox, oy);
     }

}

Hope that will help you &;)
