A set of flags specifying various characteristics of the field (see Table 8.70
on page 676, Table 8.75 on page 686, Table 8.77 on page 691, and Table 8.79 on page
693). When imported into an interactive form, the value of this entry replaces that of
the
Ff
entry in the form’s corresponding field dictionary. If this field is present, the
Set-
Ff
and
ClrFf
entries, if any, are ignored.
(Optional)
A set of flags to be set (turned on) in the
Ff
entry of the form’s cor-
responding field dictionary. Bits equal to 1 in
SetFf
cause the corresponding bits in
Ff
to be set to 1. This entry is ignored if an
Ff
entry is present in the FDF field dictionary.
(Optional)
A set of flags to be cleared (turned off) in the
Ff
entry of the form’s corre-
sponding field dictionary. Bits equal to 1 in
ClrFf
cause the corresponding bits in
Ff
to
be set to 0. If a
SetFf
entry is also present in the FDF field dictionary, it is applied be-
fore this entry. This entry is ignored if an
Ff
entry is present in the FDF field dictio-
nary.
(Optional)
A set of flags specifying various characteristics of the field’s widget annota-
tion (see Section 8.4.2, “Annotation Flags”). When imported into an interactive form,
the value of this entry replaces that of the
F
entry in the form’s corresponding annota-
tion dictionary. If this field is present, the
SetF
and
ClrF
entries, if any, are ignored.
(Optional)
A set of flags to be set (turned on) in the
F
entry of the form’s correspond-
ing widget annotation dictionary. Bits equal to 1 in
SetF
cause the corresponding bits
in
F
to be set to 1. This entry is ignored if an
F
entry is present in the FDF field dictio-
nary.
(Optional)
A set of flags to be cleared (turned off) in the
F
entry of the form’s corre-
sponding widget annotation dictionary. Bits equal to 1 in
ClrF
cause the correspond-
ing bits in
F
to be set to 0. If a
SetF
entry is also present in the FDF field dictionary, it
is applied before this entry. This entry is ignored if an
F
entry is present in the FDF
field dictionary.
(Optional)
An appearance dictionary specifying the appearance of a pushbutton field
(see “Pushbuttons” on page 686). The appearance dictionary’s contents are as shown
in Table 8.19 on page 614, except that the values of the
N
,
R
, and
D
entries must all be
streams.
(Optional; PDF 1.3)
A dictionary holding references to external PDF files containing
the pages to use for the appearances of a pushbutton field. This dictionary is similar to
an appearance dictionary (see Table 8.19 on page 614), except that the values of the
N
,
R
, and
D
entries must all be named page reference dictionaries (Table 8.100 on page
721). This entry is ignored if an
AP
