  • Abstract
    Rotation of graphical objects consisting of nested subpictures by multiples of 90° can be achieved by adding or subtracting the rotational parameters. This is much simpler than the matrix multiplication usually assumed. The technique is particularly useful in integrated-circuit design, since `objects¿ are only rotated by multiples of 90°.
