[Processing - Arduino] Send multiple data with Serial from Processing to Arduino

hey guys,

i know subject problem recurrent didn't find solution problem.
i want "stream" picture rainbowduino link arduino uno. that, use processing analyse et getpixel rgb value each 8x8 pixel of image. till this, there no matter.

now have send these datas arduino , there matter. didn't manage send data 1 per 1 arduino. it's arduino didn't understand processing data corresponding arduino data.

here code, maybe me newbie problem

arduino code :

code: [select]

i#include <rainbowduino.h>

int xwidth;
int yheight;
int color;

void setup(){
  serial.begin(9600);
  rb.init();
}

void loop(){
  if (serial.available() >= 3){
    xwidth = serial.read();
    yheight = serial.read();
    color = serial.read();
    //serial.println (xwidth);
    //serial.println(yheight);
    serial.println(color);
    rb.setpixelxy(xwidth, yheight, color, color, color);   
  } else {
    serial.println("nothing detected");
    (int = 0; < 8; i++){
      for(int j = 0; j < 8; j++){
        rb.setpixelxy(i, j, 0, 0, 0);
      }
    }
  }

   delay(2000);
}


processing code :

code: [select]

import processing.serial.*;

serial myport;
pimage myimage;
int loc = 0;
int xwidth = 0;
int yheight = 0;

void setup(){
 size(8, 8);
 myimage = loadimage("flv.png");
 println(serial.list());
 string portname = serial.list()[2];
 myport = new serial(this, portname, 9600);
}

void draw(){
 image(myimage, 0, 0);

 for(int x = 0; x < myimage.width; x++){
   for(int y = 0; y < myimage.height; y ++){
     loc = y + x*height;
     xwidth = x;
     yheight = y;
     string red = hex((int)red(myimage.get(x,y)));
     string green = hex((int)green(myimage.get(x,y)));
     string blue = hex((int)blue(myimage.get(x,y)));
     //println("a la position ", loc, " r = ", red, ", g : ", green, ", b : ", blue);
     
     myport.write(xwidth);
     println("x: ", xwidth, "sent");
     myport.write(yheight);
     println("y : ", yheight, "sent");
     myport.write(red);
     println("color : ", red, "sent");
     delay(2000);
     
     if (loc == 63){
       println("--- finish ---");
     }
   }
 }
}



thank !

edit : fixed code problem. robin !

neither of pieces of code looks arduino code.
