rectangle
(Optional; PDF 1.6)
A set of four numbers describing the numerical differences
between two rectangles: the
Rect
entry of the annotation and a rectangle con-
tained within that rectangle. The inner rectangle is where the annotation’s text
should be displayed. Any border styles and/or border effects specified by
BS
and
BE
entries, respectively, are applied to the border of the inner rectangle.
The four numbers correspond to the differences in default user space between
the left, top, right, and bottom coordinates of
Rect
and those of the inner rectan-
gle, respectively. Each value must be greater than or equal to 0. The sum of the
top and bottom differences must be less than the height of
Rect
, and the sum of
the left and right differences must be less than the width of
Rect
.
BS
dictionary
(Optional; PDF 1.6)
A border style dictionary (see Table 8.17 on page 611) speci-
fying the line width and dash pattern to be used in drawing the annotation’s bor-
der.
Note:
The annotation dictionary’s
AP
entry, if present, takes precedence over the
In-
kList
and
BS
entries; see Table 8.15 on page 606 and Section 8.4.4, “Appearance
LE
array
(Optional; PDF 1.6)
An array of two names specifying the line ending styles to be
used in drawing the annotation’s border. The first and second elements of the ar-
ray specify the line ending styles for the endpoints defined, respectively, by the
first and second pairs of coordinates, (
