Blair MacIntyre July 2, 1992 11:25 am PDT The precision specifies how tight a bounding box will be created. conic: arcs are converted to conics, conics are bounded by the bounding box of the triangle [p0, p1, p2], curves are bounded by the bounding box of the quadrilateral [p0, p1, p2, p3], moves are bounded by the trivial bounding box around [p0], lines are bounded by the box around [p0, p1]. curve: arcs are converted to conics, conics are converted to curves, curves are bounded by the bounding box of the quadrilateral [p0, p1, p2, p3], moves are bounded by the trivial bounding box around [p0], lines are bounded by the box around [p0, p1]. device: the path is converted to a devicePath, from which the bounding box is obtained. Return the smallest bounding box around the given path. Κ•NewlineDelimiter ™™Icodešœ Οeœ0™
