Layers
About PDF layers
Acrobat supports viewing, navigating, and printing layered content in PDFs created from applications such as
InDesign, AutoCAD, and Visio.
You can control the display of layers using the default and initial state settings. For example, if your document
contains a copyright notice, you can easily hide the layer containing that notice whenever the document is displayed
on-screen while ensuring that the layer always prints.
You can rename and merge layers, change the properties of layers, and add actions to layers. You can also lock layers
to prevent them from being hidden.
Acrobat does not allow you to author layers that change visibility according to the zoom level. However, you can
highlight a portion of a layer that is especially important by creating a bookmark that magnifies or hides the layer
using page actions. You can also add links that let users click a visible or invisible link to navigate to or zoom in on a
layer.
To retain layers when you convert InDesign CS or later documents to PDF, make sure that Compatibility is set to
Acrobat 6 (PDF 1.5) and that Create Acrobat Layers is selected in the Export PDF dialog box.
Show or hide layers
Information can be stored on different layers of a PDF. The layers that appear in the PDF are based on the layers
created in the original application. You cannot create layers in Acrobat; however, you can examine layers and show
or hide the content associated with each layer using the Layers panel in the navigation pane. Items on locked layers
cannot be hidden.
