8.1 version

inflate-box

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.
