Adding Navigation to PDF Documents
Setting Up a Presentation
There are two viewing modes for Acrobat and Adobe Reader: full screen mode and regular
viewing mode. Full screen mode is often appropriate for presentations, since PDF pages
can fill the entire screen with the menu bar, toolbar, and window controls hidden.
It is possible to use Acrobat JavaScript to customize the viewing mode when setting up
presentations. The
app
object’s
fullScreen
property, as well as the
app.media
object’s
windowType
property may be used to set the viewing mode.
Defining the Initial View in Full Screen View
To cause Acrobat and Adobe Reader to display in full screen mode, you may include the
following statement in a document-level script triggered when the document is opened, or
in an application-level script triggered when the application is first started:
app.fullscreen = true;
Defining an Initial View
In addition to specifying whether the full screen or regular viewing mode will be used, you
may also use Acrobat JavaScript to set up the document view. You can customize the initial
view in terms of magnification, page layout, application and document viewing
dimensions, the initial page to which the document opens, and whether parts of the user
interface will be visible.
The
doc
object’s
layout
property allows you to specify page layout by assigning one of
the following values:
●
●
●
●
●
●
SinglePage
OneColumn
TwoColumnLeft
TwoColumnRight
TwoPageLeft
TwoPageRight
To set up the dimensions of the various view windows, assign a
rect
value to one of the
following
doc
object properties:
innerAppWindowRect
: the inner application window (excludes title bar, border, etc)
●
innerDocWindowRect
: the inner document window
●
outerAppWindowRect
: the outer application window
●
outerDocWindowRect
: the outer document window
●
pageWindowRect
: the page view window for the document content
To set up the magnification, assign a value to the
doc
object’s
zoom
property. For example,
●
the following code sets up a magnification of 125%:
this.zoom = 125;
