intersect method

IntRect intersect(IntRect other)

Calculates the intersection of this rectangle with another rectangle.

other The other rectangle to intersect with. Returns a new IntRect representing the intersection area. If there is no intersection, returns an empty rectangle (width and height of 0).

Implementation

IntRect intersect(final IntRect other) {
  final int newLeft = max(left, other.left);
  final int newTop = max(top, other.top);
  final int newRight = min(right, other.right);
  final int newBottom = min(bottom, other.bottom);

  // Check if there is a valid intersection
  if (newLeft >= newRight || newTop >= newBottom) {
    // No intersection, return empty rectangle
    return IntRect.zero;
  }

  return IntRect.fromLTRB(newLeft, newTop, newRight, newBottom);
}
