ectangle-max-point Arguments: rectangle [Generic function] ■ Returns the maximum point of rectangle. (The position of a rectangle is specified by its minimum point). rectangle-edges* Arguments: rectangle [Generic function] ■ Returns the coordinate of the minimum x and y and maximum x and y of rectangle as four values. rectangle-min-x Arguments: rectangle ■ Returns the coordinate of the minimum x of rectangle. rectangle-min-y Arguments: rectangle ■ Returns the coordinate of the minimum y of rectangle. rectangle-max-x Arguments: rectangle ■ Returns the coordinate of the maximum x of rectangle. rectangle-max-y Arguments: rectangle ■ Returns the coordinate of the maximum y of rectangle. rectangle-width Arguments: rectangle [Function] [Function] [Function] [Function] [Function] ■ Returns the width of rectangle. The width of a rectangle is the difference between the maximum x and the minimum x. (The height of a rectangle is difference between the maximum y and the minimum y.) rectangle-height Arguments: rectangle [Function] ■ Returns the height of rectangle. The height is the difference between the maximum y and the minimum y. (The width of a rectangle is the difference between the maximum x and the minimum x.) rectangle-size Arguments: rectangle ■ Returns two values, the width and the height of rectangle.

3.6.7 Bounding Rectangles in CLIM Every bounded region in CLIM has a derived bounding rectangle, which is the smallest rectangle that contains every point in the region, and may contain additional points as well. Unbounded regions do not have any bounding rectangle. For example, all windows and output records have bounding rectangles whose coordinates are relative to the bounding rectangle of the parent of the window or output record. Note that bounding-rectangles are distinct from rectangles. Bounding-rectangles are used internally in CLIM for a number of purposes. Note that when you are asked to provide a bounding-rectangle, supplying a rectangle instead may not cause an immediate error but will likely cause a subsequent failure, often one that is hard to diagnose. bounding-rectangle [Class] ■ The protocol class that represents a bounding rectangle. Note that bounding rectangles are not a subclass of rectangle, nor even a subclass of region. This is because in general, bounding rectangles do not obey the region protocols. However, all bounded rectangles and sheets that obey the bounding rectangle protocol are subclasses of bounding-rectangle. standard-bounding-rectangle [Class] ■ An instantiable class that implements a bounding rectangle. this is a subclass of both rectangle and bounding-rectangle, that is standard bounding rectangles obey the rectangle protocol. make-bounding-rectangle returns an object of this class. make-bounding-rectangle Arguments: x1 y1 x2 y2 [Function] ■ Returns an object of the class standard-bounding-rectangle with the edges specified by the arguments, which must be real numbers. Two opposite corners of the resulting bounding rectangle have coordinates ((min x1 x2), (min y1 y2)) and ((max x1 x2), (max y1 y2)), with the other two corners determined in the obvious way. The following functions can be used to access the bounding rectangle of a region. bounding-rectangle* [Generic function] Arguments: region ■ Returns the bounding rectangle of region as four real numbers specifying the left, top, right, and bottom edges of the bounding rectangle. region must be a bounded region, such as an output record, a window, or a geometric object such as a line or an ellipse. ■ The coordinates of the bounding rectangle of windows and output records are maintained relative to the parent of the window or output record. bounding-rectangle [Generic function] Arguments: region &optional reuse-rectangle ■ Returns the bounding rectangle of region as a rectangle object. region is as for bounding-rectangle*.
