operator [] method

int operator [](
  1. int i
)

A coordinate value by the coordinate axis index i.

Returns zero when a coordinate axis is not available.

For scalable coordinates, the coordinate ordering is: (zoom, x, y)

Implementation

int operator [](int i) {
  switch (i) {
    case 0:
      return zoom;
    case 1:
      return x;
    case 2:
      return y;
    default:
      return 0;
  }
}
