What it does
Removes the selected layers. You can choose whether or not to remove the objects on
these layers as well:
- To keep all objects, regardless of their visibility, select Make
all elements visible. All objects (including hidden objects)
will become visible after the layers have been removed.
- To keep all objects based on their default visibility, select
Preserve the initial view of the PDF. Objects on
layers with default visibility turned on are preserved (and remain
visible). All other objects (i.e. by default hidden objects) are
removed.
- To keep all objects based on their current visibility, select
Preserve the current view of the PDF. Objects on
visible layers are preserved, regardless of their default visibility state.
All other objects (i.e. currently hidden objects) are removed.
About PDF layers
Layered content usually comes from applications such as InDesign, AutoCAD or Visio.
When converted to PDF, the layers are retained and can be viewed and navigated in
Adobe Acrobat. However, if you print a PDF file that contains layers, only the
content that is visible on-screen is printed. This may or may not be desired.
"Conventional" layers versus PDF layers
Layers in digital image editing ("conventional" layers) are used to separate
the different elements of an image. Each element is drawn on exactly one layer. The
different layers are stacked on top of each other, and the order of the layers
defines how the image looks like.
Layers in PDF have a different meaning. They are used to hide or show page
content:
- Turning on a layer, all objects on this layer are shown
on-screen.
- Turning off a layer, all objects on this layer are hidden, i.e. they
become invisible.
As such, layers are also called "optional content groups": groups of objects
that can be selectively viewed or hidden by the author of the document. Objects can
belong to different layers, and the order of the layers is of no importance.
