Description

ffInvisible

If set, do not display the field if it does not belong to one of the standard

field types and no field handler is available.

ffHidden

(PDF 1.2) If set, do not display or print the field or allow it to interact

with the user, regardless of its field type or whether an field handler is

available.

ffPrint

(PDF 1.2) If set, print the field when the page is printed. If clear, never

print the field, regardless of whether it is displayed on the screen. This

can be useful, for example, for fields representing interactive

pushbuttons, which would serve no meaningful purpose on the printed

page.

ffNoZoom

(PDF 1.3) If set, do not scale the field’s appearance to match the

magnification of the page. The location of the field on the page (defined

by the upper-left corner of its field rectangle) remains fixed, regardless of

the page magnification.

ffNoRotate

(PDF 1.3) If set, do not rotate the field’s appearance to match the rotation

of the page. The upper-left corner of the field rectangle remains in a fixed

location on the page, regardless of the page rotation.

ffNoView

(PDF 1.3) If set, do not display the field on the screen or allow it to

interact with the user. The field may be printed (depending on the setting

of the ffPrint flag), but should be considered hidden for purposes of on-

screen display and user interaction.

ffReadOnly

(PDF 1.3) If set, do not allow the field to interact with the user. The field

may be displayed or printed (depending on the settings of the afNoView

and ffPrint flags), but should not respond to mouse clicks or change its

appearance in response to mouse motions.

ffRequired

If set, the field must have a value at the time it is exported by a submit-

form action (see CreateSubmitAction() for further information).

Supported by all fields except group fields.
