CHAPTER 8 Interactive Features
KEY TYPE VALUE
S name (Optional) The type of scaling to use:
A Anamorphic scaling: Scale the icon to fill the annotation rectangle exactly, with-
out regard to its original aspect ratio (ratio of width to height).
P Proportional scaling: Scale the icon to fit the width or height of the annotation
rectangle while maintaining the icon’s original aspect ratio. If the required hori-
zontal and vertical scaling factors are different, use the smaller of the two, cen-
tering the icon within the annotation rectangle in the other dimension.
Default value: P.
A array (Optional) An array of two numbers between 0.0 and 1.0 indicating the fraction of left-
over space to allocate at the left and bottom of the icon. A value of [ 0.0 0.0 ] positions the
icon at the bottom-left corner of the annotation rectangle. A value of [ 0.5 0.5 ] centers it
within the rectangle. This entry is used only if the icon is scaled proportionally. Default
value: [ 0.5 0.5 ].
FB boolean (Optional; PDF 1.5) If true, indicates that the button appearance should be scaled to fit
fully within the bounds of the annotation without taking into consideration the line
width of the border; see implementation note 136 in Appendix H. Default value: false.
FDF Pages
The optional Pages field in an FDF dictionary (see Table 8.93 on page 714)
contains an array of FDF page dictionaries (PDF 1.3) describing new pages to be
added to the target document. Table 8.98 shows the contents of this type of
dictionary.

KEY TYPE VALUE
Templates array (Required) An array of FDF template dictionaries (see Table 8.99) describing the
named pages that serve as templates on the page.
Info dictionary (Optional) An FDF page information dictionary containing additional informa-
tion about the page. At the time of publication, no entries have been defined for
this dictionary.
