    • contains

      public static boolean contains(double rx, double ry, double rw, double rh, double x, double y, double tolerance)
      Returns true if the bounds contain the specified point within the given tolerance.
      Parameters:
      rx - the bounds x-coordinate
      ry - the bounds y-coordinate
      rw - the bounds width
      rh - the bounds height
      x - the x-coordinate of the point
      y - the y-coordinate of the point
      tolerance - the tolerance
      Returns:
      true if inside

    • containsAWT

      public static boolean containsAWT(@NonNull Rectangle2D r1, @NonNull Rectangle2D r2)
      Returns true, if rectangle 1 contains rectangle 2.

      This method is similar to Rectangle2D.contains, but also returns true, when rectangle1 contains rectangle2 and either or both of them are empty.

      Parameters:
      r1 - Rectangle 1.
      r2 - Rectangle 2.
      Returns:
      true if r1 contains r2.
