Editing the properties of Adobe PDF layers
You can rename or lock Adobe PDF layers, set the default state, and set the initial
visibility, print, and export states in the Layer Properties dialog box.
You can combine the default state setting, the visibility setting, and the print setting to
control when a layer is visible and when it prints. If a layer contains a watermark, for
example, you may want the layer to not show on-screen but always to print and always to
export to other applications. In this case you can set the default state to on, the initial
visibility to never visible (the image doesn't show on-screen), and the initial print and
initial export states to always print and always export. The layer need not be listed in the
Layers tab, since all the state changes are handled automatically.
Note: The settings in the Layer Properties dialog box take effect only if Allow Layer State
To Be Set By User Information is selected in the Startup preferences. If it is not selected,
Layer Properties dialog box settings, other than Layer Name and Default State, are
ignored.
To edit the properties of PDF layers:
1. Click the Layers tab.
2. Select a layer, and choose Layer Properties from the Options menu.
3. In the Layer Properties dialog box, do any of the following, and then click OK:
l
Enter the new layer name in the text box.
l
Set the Default State. The Default State setting defines the initial visibility state of the
layer when a document is first opened or when the initial visibility is reset. The eye icons
for layers are initially shown or hidden based on this value. For example, if this value is
set to off, the eye icon for a layer is hidden when the document is first opened or when
Reset To Initial Visibility is chosen from the Options menu.
l
For Intent, select View to allow the layer to be turned on or off, or select Reference to
keep the layer on at all times and permit editing of the properties. When the Reference
Intent option is selected, the layer appears in italics.
l
Choose a Visibility option to define the on-screen visibility of the PDF layer. You can
show a layer when the document is opened, you can hide a layer when the document is
opened, or you can let the default state determine whether a layer is shown or hidden
when the document is opened.
l
Choose a Print option to determine whether a layer will print.
l
Choose an Export option to determine whether the layer appears in the resulting document
when the PDF file is exported to an application or file format that supports layers.
Any additional properties that the creator of the layered PDF document has associated
with a specific layer are shown in the box at the bottom of the Layer Properties dialog box.

Adding navigability to layers
You can add links and destinations to layers, allowing you to change the view of a
document when the user clicks a bookmark or link.
Note: In general, changes to layer visibility made using the eye icon in the Layers tab are
not recorded in the Navigation toolbar.
To associate layer visibility with bookmarks:
1. Set the required layer properties, visibility, and magnification level for the target PDF
layer in the document pane.
2. Click the Bookmarks tab, and choose New Bookmark from the Options menu.
3. Select the new bookmark, and choose Properties from the Options menu.
4. In the Bookmark Properties dialog box, click the Action tab.
5. For Select Action, choose Set Layer Visibility, and click Add.
6. Click Close.
7. Select the bookmark label in the Bookmarks tab, and name the bookmark.
To associate layer visibility with a link destination:
1. Set the required layer properties for the destination in the document pane.
2. Choose View > Navigation Tabs > Destinations, and choose Scan Document from the
Options menu.
3. Click the Create New Destination button
or select New Destination from the Options
menu, and name the destination.
4. Select the Link tool
, and drag in the document pane to create a link. (Because content
is added to all layers, it doesn't matter that you are apparently creating the link on the
target layer. The link works from any layer.)
5. In the Create Link dialog box, select Custom Link and click Next.
6. Click the Appearance tab in the Link Properties dialog box, and set the appearance of the
link. (See
Changing the appearance of links.)
7. Click the Actions tab in the Link Properties dialog box, choose Set Layer Visibility, and
click Add.
8. Close the dialog boxes.
You can test the link by changing the layer settings, selecting the Hand tool, and clicking
the link.
14
Merging layers
You can merge one or more layers in an Adobe PDF document. Merged layers acquire the
properties of the layer into which they are merged (the target layer). The merging of layers
cannot be undone.
To merge layers in a PDF document:
1. Click the Layers tab, and select Merge Layers from the Options menu.
2. In the left pane (Layers To Be Merged), select one or more layers to be merged. Ctrl-click
(Windows) or Command-click (Mac OS) to select multiple layers, and click Add. Click
Add All to merge all layers.
3. To remove a layer from the center panel, select the layer or layers. Ctrl-click (Windows)
or Command-click (Mac OS) to select multiple layers. When your selection is complete,
click Remove.
4. In the right pane (Layer To Be Merged Into), select the layer into which to merge the
selected layers, and click OK.
5
Flattening Adobe PDF layers
Flattening Adobe PDF layers hides any content that is not visible when the flattening
operation is executed. Layers are consolidated, and the flattening action cannot be undone.
To flatten layers:
Click the Layers tab, and select Flatten Layers from the Options menu.
22
Editing layered content
You can select or copy content in a layered Adobe PDF document using the Select tool or
the Snapshot tool. You can edit content using a touch-up tool. These tools recognize and
select any content that is visible, regardless of whether the content is on a selected layer.
(See
Editing text with the TouchUp Text tool.) You can also use the TouchUp Object tool
to edit images. (See
Editing images using the TouchUp Object tool.)
If the content that you edit or delete is associated with one layer, the content of the layer
reflects the change. If the content that you edit or delete is associated with more than one
layer, the content in all the layers reflects the change. For example, if you want to change
a title and byline that appear on the same line on the first page of a document, and the title
and byline are on two different visible layers, editing the content on one layer changes the
content on both layers.
You can add content, such as review comments, stamps, or form fields, to layered
documents just as you would to any other PDF document. However, the content is not
added to a specific layer, even if that layer is selected when the content is added. Rather,
the content is added to the entire document.
You can use the Create PDF From Multiple Files command to combine Adobe PDF
documents that contain layers. The layers for each document are grouped under a separate
heading in the Layers tab of the navigation pane. You expand and collapse the group by
clicking the icon in the title bar for the group.

About file attachments
Acrobat lets you attach PDF and other files to an Adobe PDF document so that the reader
can open them for viewing. If you move the PDF document to a new location, the
attachments automatically go with it. You can add two types of file attachments to PDF
documents from the File toolbar: document-level attachments and page-level attachments.
Document-level attachments are added by using the Attach A File tool
and may
include links to or from the parent document or to other file attachments. (See
Linking
between files.) Page-level attachments are added as comments by using various tools to
add sound files and documents. (See
Adding attachments as comments.) Comment, or
page-level, attachments display the File Attachment icon
or the Speaker icon
on
the page where they're located.
If a PDF document contains an attachment, the File Attachment icon
appears in the
status bar. You can view a tool tip with the total number of attachments by placing the
pointer over the icon. The Attachments tab lists all the attachments in the PDF document,
including the name, a description, the modification date, and the file size. Page-level
attachments also include the page number of their location.
Use the Attachments tab to add, delete, or view attachments.

Opening and saving attachments
Opening and saving attachments is simple in Acrobat. However, you must have an
application installed that can handle the file format of the attachment. You can open a
PDF attachment in Acrobat and make changes to it--if you have permissions to do so--and
your changes are applied to the PDF attachment. When you open a non-PDF attachment,
you have an option of opening or saving the file; opening the file starts the application that
handles the file format of the attachment. Any changes you make to a non-PDF
attachment are not applied to the attachment. Instead, save changes to the file, and then
reattach it to the primary PDF document. (See
Saving modified files into the primary
Adobe PDF document.)
To open an attachment:
1. In the Attachments tab, select the attachment.
2. Click Open, or choose Open from the Options menu.
To save a copy of one or more attachments:
1. In the Attachments tab, select one or more attachments.
2. Click Save, or choose Save from the Options menu.
3. Save the attachments:
l
To save a single attachment, name the file, specify a location, and then click Save.
l
To save multiple attachments, specify a location, and then click Save.

Saving modified files into the primary Adobe PDF
document
If you make changes to a non-PDF attachment, you must delete the existing file
attachment in the primary PDF document and then create a new file attachment with the
modified document.

Working with attachments created in Acrobat 6.0 or earlier
In Acrobat 7.0, you can view and save attachments in PDF files that were created in
Acrobat 5.0 or 6.0. To ensure that attachments you created in Acrobat 7.0 open in earlier
versions of Acrobat, save a PDF file that contains an attachment with the option to show
attachments when the file is opened.
To create attachments that can be viewed in Acrobat 5.0 or 6.0:
1. Add a PDF attachment to the document. (See
Adding attachments to Adobe PDF
documents.)
2. Do one of the following:
l
Click the Attachments tab, and select Show Attachments By Default from the Options
menu (selected by default).
l
Choose File > Document Properties, click the Initial View tab, choose Attachments Panel
And Page from the Show menu, and click OK.
3. Save the PDF document.
