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
