Demo of Code Being Embedded

Hello, this is my code for that thing:

  void setup() {
  loadShoeImage(); 

  int w = 256; 
  int h = 256; 
  if ((shoeImage != null) && (shoeImage.width > 0)) {
    bShoeImageLoaded = true;
    w = shoeImage.width;
    h = shoeImage.height;
    binarizedShoeImage = createImage (w, h, RGB);
  }
  size (w, h);
  noLoop();

  firstPixel = new Point2d(0, 0);
  chain = new ArrayList();
  process();
} 

Hope you like it!
