TIP 95: Bookmarking a Layered Document
Acrobat lets you attach bookmarks to layers, which you can use in different ways. For example, you can distribute the same information using different languages without having to provide documents in different languages, or you can show customers samples in different colors in the same document. Use bookmarks in conjunction with layers to give readers control over what they see and print. Use actions to extend the function of a bookmark beyond just pointing to a location in your document.
Different Types of Layers
What you see in the Layers pane depends on how the original document was constructed and converted. In some cases, a document is converted with preserved layers, as in our example. In other cases, the document layers may be flattened or locked. In a flattened document you see a single layer like a regular PDF document. A locked document, on the other hand, displays the layers individually, but they can't be edited in any way. |
Our sample document has three layers, each having a different color scheme and details. Follow these steps to bookmark a layered document:
1. | Open the Bookmarks pane and add three bookmarks. At this point, if you click any bookmark it displays the same location on the same page. | 2. | Select each bookmark and name it (Figure 95a). To minimize confusion, name the bookmarks and arrange them in the same order as the layers listed on the Layers pane.
Figure 95a. Use a set of bookmarks linked to layers in a document.
| 3. | On the Layers pane, toggle all layers but autumn to off by clicking the eye icons. Set the destination view for the autumn title bookmark to display only the autumn layer, as shown in Figure 95a. | 4. | On the Bookmarks pane, right-click/Control-click the autumn bookmark to select it and open the shortcut menu. Choose Properties to open the Bookmark Properties dialog and then click the Actions tab. | 5. | From the Select Action pull-down menu, select Set Layer Visibility and then click Add. The action automatically appears in the Actions section at the bottom of the dialog (Figure 95b).
Figure 95b. Choose the Set layer visibility action in the Actions tab.
Note A bookmark's action is to display a page as shown in the bottom of the window in Figure 95b. You can delete the action or leave it as is. In this case, it doesn't make any difference. | 6. | A notification dialog appears to tell you that the target layer state of the selected actions will be set to the current state. In other words, set the destination layer you want to see as a result of clicking a bookmark and leave the rest hidden. Click OK. The action is added to the Actions list. | 7. | Click Close to close the Bookmark Properties dialog. | 8. | Repeat with the other layers. Be sure to hide all layers except for the one you are attaching to the bookmark. |
