Thread: Vertical mirror help

I'm new to Java and I really need some help! I need to write a method to mirror the left half of a picture to the right half of the picture motorcycle.jpg (see attachment for example). I have a method, but it flips the image and copies it to a new picture. I need the method to take half of the image and mirror it over the other half of the image. Please help!

 
public Picture flip() {
    Pixel currPixel = null;
    Pixel targetPixel = null;
    Picture target = 
      new Picture(FileChooser.pickAFile());
 
    for (int srcX = 0, trgX = getWidth()-1; 
         srcX < getWidth();
         srcX++, trgX--) {
      for (int srcY = 0, trgY = 0; 
           srcY < getHeight();
           srcY++, trgY++) {
 
        // get the current pixel
        currPixel = this.getPixel(srcX,srcY);
        targetPixel = target.getPixel(trgX,trgY);
 
        // copy the color of currPixel into target
        targetPixel.setColor(currPixel.getColor());
      }
    }
    return target;
  }
