KEY
TYPE
VALUE
Inset
The border makes the entire box look as though it were
embedded in the canvas.
The border makes the entire box look as though it were
coming out of the canvas (the opposite of
Inset
).
Outset
Default value:
None
Note:
All borders are drawn on top of the box’s background. The color of bor-
ders drawn for values of
Groove
,
Ridge
,
Inset
, and
Outset
depends on the struc-
ture element’s
BorderColor
attribute and the color of the background over which
the border is being drawn.
Note:
Conforming HTML applications may interpret Dotted, Dashed, Double,
Groove, Ridge, Inset, and Outset to be Solid.
BorderThickness
number or
array
(Optional; inheritable; PDF 1.5)
The thickness of the border drawn on the
edges of a table cell or any element’s content rectangle (possibly adjusted by
the
Padding
attribute). The value of each edge is a positive number in default
user space units representing the border’s thickness (a value of 0 indicates
that the border is not drawn). There are two forms:
•
A number representing the border thickness for all four edges.
•
An array of four entries, each entry specifying the thickness for one edge of
the border, in the order of the before, after, start, and end edges. A value of
null
for any of the edges means that it is not to be drawn.
Padding
number or
array
(Optional; not inheritable; PDF 1.5)
Specifies an offset to account for the sep-
aration between the element’s content rectangle and the surrounding border
(see “Content and Allocation Rectangles” on page 930). A positive value en-
larges the background area; a negative value trims it, possibly allowing the
border to overlap the element’s text or graphic.
The value is either a single number representing the width of the padding, in
default user space units, that applies to all four sides or a 4-entry array repre-
senting the padding width for the before, after, start, and end edge, respec-
tively, of the content rectangle. Default value: 0.
Color
array
(Optional; inheritable; PDF 1.5)
The color to be used for drawing text and the
default value for the color of table borders and text decorations. The value is
an array of three numbers in the range 0.0 to 1.0, representing the red, green,
and blue values, respectively, of an RGB color space. If this attribute is not
specified, the border color for this element is the current text fill color in ef-
fect at the start of its associated content.
