8.2.4 Collections 29
Beginning with extension level 3, a portable collection can include a SWF file that creates an interactive
layout, or presentation, of the collection contents. The SWF file that manages the collection presentation is
called a
navigator
. For more information about navigators, see
“Navigators” on page 34
.
The collection dictionary contains some entries that support navigators. The
Navigator
entry is an
indirect reference to a navigator dictionary that contains a reference to the SWF file that describes the
layout. The
Resources
entry is an indirect reference to a name tree that can describe the content and
display of a header and welcome page of a portable collection. The value of the
Colors
entry is a
collection colors dictionary
that specifies a suggested set of colors for use by a collection navigator. The
Folders
entry is an indirect reference to the root folder of the collection’s folder structure.
The
View
entry of Table 8.6 has an additional value of
C
, and unchanged content is shown in gray. Add the
entries
Navigator
,
Resources
,
Colors
,
Folders
, and
Split
to Table 8.6 in support of portable
collections that use navigators.
