TABLE 10.17 Property list entries for artifacts
KEY
SUBTYPE
DESCRIPTION
Subtype
name
(
Optional; PDF 1.7
) The subtype of the artifact. This entry applies only
when the
Type
entry has a value of
Pagination
. Valid values are
Header
,
Footer
, and
Watermark.
Additional values can be defined
for this entry, provided they comply with the naming conventions
described in Appendix E.
ExtensionLevel 3 adds
BatesN
to the set of valid values.
Contents
text string or
array of text
string
(
Optional; ExtensionLevel 3
) The artifact content, which applies when
Subtype
has a value of
BatesN
. If this artifact applies to a page that
contains a single Bates Number, the
Contents
value is a Bates
Numbering string.
If this artifact applies to a page that contains multiple Bates Numbers,
the
Contents
value is an array of text strings, each of which contains a
concatenation of the Bates Numbering parts. The order in which the
text strings appear in the array is application-dependent.
Note:
Typically, applications that support Bates Numbering add private
data to the PDF document that specifies starting values for Bates
Numbering, and placement and formatting of those values. The
intent of Bates Numbering values provided in this artifact content
is to override Bates Numbering values in the private data.
