程式碼:

//pixels[i] 可以得到畫面中的每個pixels

PImage img;

color nowColor;

void setup(){

  size(1200,779);

  img=loadImage("cloud.png");

}

void draw(){

  image(img,0,0);

  fill(nowColor); rect(0,0,30,30);

}

void mouseMoved(){

  loadPixels();//(1)取得畫布

  int now = width*mouseY + mouseX;

  nowColor = pixels[now];

  //for(int i=0; i<width*height; i++){//(2)迴圈

  //pixels[i]//(3)取得pixels

  }
