Creating Layered PDF Files
The PDFMakers for several engineering applications, including Microsoft Visio and 
AutoCad, automatically generate the necessary ProcSets to create layered PDF documents. 
Third-party developers must insert OC ProcSet information into the PostScript stream. For 
more details, see 
 
and the Acrobat Distiller API Reference.
You create layered PDF documents with the ProcSet used to build Optional Content (OC) 
into PDF through Acrobat Distiller. 
Navigating with Layers
Since information can be stored in different layers of a PDF document, navigational controls 
can be customized within different layers, whose visibility settings may be dynamically 
customized so that they are tied to context and user interaction. For example, if the user 
selects a given option, a set of navigational links belonging to a corresponding optional 
content group can be shown.
Working with Layers from Acrobat JavaScript
Using Acrobat JavaScript, you can determine the order in which layers are displayed in the 
user interface. 
You can also use Acrobat JavaScript to:
Merge layers in a PDF document
Flatten layers in a PDF document
Combine PDF layered documents
For more information, see the Acrobat JavaScript Scripting Guide.
