In what order is the following code processing the image pixels?

Picture pic("queen-mary.png");
for (int x = 0; x < pic.width(); x++)
   {
      for (int y = 0; y < pic.height(); y++)
      {
         int red = pic.red(x, y);
         int green = pic.green(x, y);
         int blue = pic.blue(x, y);
         pic.set(x, y, 255 - red, 255 - green, 255 - blue);
      }
   }

Diagonally

Across each row, then down the left side of the next row

Down each column, then over the top of the next column

Impossible to tell from this snippet of code
