Halo :]

Check this code (compile in Processing):
(You'll need the controlP5 library)

import javax.swing.*;
import controlP5.*;
ControlP5 controlP5;

public PImage img;
PImage a;

JFrame new_window;
MApplet imageviewer;

void setup()
{
 size(400,800);
 background(50);
 //noLoop();
 controlP5 = new ControlP5(this);
   
 Controller imgLoad = controlP5.addButton("load",1,10,10,80,20);
 imgLoad.setId(1);
 
 Controller imgInvert = controlP5.addButton("invert",3,10,100,80,20);
 imgInvert.setId(2);
}

void draw() {
 controlP5.draw();
}

void controlEvent(ControlEvent theEvent) {
 println("ID =  "+theEvent.controller().id());
 switch(theEvent.controller().id()) {
   case(1):
     loadNewImage();
   break;
   
   case(2):
     imageviewer.negatyw();
     println("OK");
   break;
   
   case(3):
     //negatyw();
   break;
 
   case(4):
     //r_g_b();
   break;  
 }
}



void loadNewImage() {
 // pick image to display in a new window
 FileDialog fd = new FileDialog(this.frame);
 fd.setMode(FileDialog.LOAD);
 fd.setLocation(50, 50);
 fd.show();
 String dir = fd.getDirectory();
 String file = fd.getFile();
 if( dir != null && file != null &&  
(
  file.indexOf(".jpg") != -1 ||  
  file.indexOf(".png") != -1 ||
  file.indexOf(".PNG") != -1 ||  
  file.indexOf(".gif") != -1 ||  
  file.indexOf(".jpeg") != -1 ||
  file.indexOf(".JPEG") != -1 ||
  file.indexOf(".JPG") != -1 ||
  file.indexOf(".tif") != -1 ||
  file.indexOf(".bmp") != -1
)
   ){
   // load image
   img = loadImage(dir+file);
   PImage ob = createImage(0, 0, RGB);
   ob=img;
   ob.resize(200,200);
   //img.resize(10,10);
   image(ob,200,400);
   
   // open the window / change the content
   if(new_window == null) {
    new_window = new JFrame(file);
    // create the image viewer applet
    imageviewer = new MApplet();
    // add the image viewer applet
    new_window.getContentPane().add(imageviewer, BorderLayout.CENTER);
    // set it to not be resizable
    //new_window.setResizable(false);
    // show it
    new_window.setVisible(true);
    // init
    imageviewer.init();
    }
   // size it
   new_window.setSize(img.width,img.height);
 }
 imageviewer.redraw();
}

public class MApplet extends PApplet {
 public void setup() {
   size(img.width,img.height);
   background(img);
   noLoop();
 }
     
 public void draw() {
   //image(img,0,0);
   //imageviewer.redraw();
 }
 
 public void negatyw() {
 a=img;
 a.loadPixels();
 for (int i = 0; i < a.pixels.length; i++ ) {
   float r = red (a.pixels[i]);
   float g = green (a.pixels[i]);
   float b = blue (a.pixels[i]);
   r = 255 - r;
   g = 255 - g;
   b = 255 - b;
   color c = color(r,g,b);
   a.pixels[i] = c;
 }
 a.updatePixels();
 //a=img;
 image(a,0,0);
 redraw();
}
}


NOW Please WHY image "a" is resized on the second window too ?
I need to display resized source image on the first window
than modiffy it and dosplay on the second window with origin size.
Please HELP.
