| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: box dx dy
Modifies and returns box by subtracting
dx from its left, and adding it to its right; and
subtracting dy from its top, and adding it to its
bottom. The result, which is returned, is a box (* 2
dx)
wider and (* 2 dy)
higher. dx and dy must be
fixnums. This function is effectively equivalent to
(setq box (nmake-box box (- (box-left box) dx) (- (box-top box) dy) (+ (box-right box) dx) (+ (box-bottom box) dy)))
See the description of the box
class and make-box for information on
boxes. See nmake-box, which modifies an
existing box rather than creating a new one.
