Layers contain page content that can be displayed/hidden as desired. They are a useful feature in cases where documents need to feature a varying appearance depending on the intended audience. For example it is possible to create text-based layers that each feature a different language and fit over image-based content. The desired layer can then be enabled in order to match the language of the target audience:
