TIP 94: Working with a Layered Document

Acrobat 7 Professional allows you to work with layered documents created in Visio and AutoCAD. Unfortunately, layered documents created in programs such as Adobe Photoshop are not supported.

This tip uses a document with three named layers created in Microsoft Visio 2003. Our document displays a graphic of kitchen cabinets with three alternate color schemes for the tile. The default view (Figure 94a) shows some of the content of all layers simultaneously (looks a bit messy, doesn't it?). If you come across a document like this, have a look at the bottom left of the Acrobat window. If you see a "layer cake" icon , you know the document is layered. Click the Layers tab in the Navigation pane to open the Layers pane. If the Layers tab isn't visible in the Navigation pane, choose View > Navigation Tabs > Layers to open the tab.

In Figure 94b, you can see that our document has three named layers; each corresponds to the individual layer's color scheme.

You can toggle a layer's visibility on and off by clicking the eye iconwhen the eye is visible, the layer is visible. In the figure, only the ocean waves layer is set to visible, and the content on the layer appears on the Document pane.

As with other documents, you may be able to make changes to the content (depending on the rights granted by the document's author). Our sample doesn't have security attached, so you can add comments to it or export it in another file format from Acrobat.

To see what a layer contains, right-click it on the Layers pane and choose Layer Properties to open the dialog (Figure 94c). The Layer Properties dialog lists information about the layer, including its original name, visibility, print status, and export status. Keep in mind that settings applied to the original layered document cannot be changed. For example, our sample document uses the Prints When Visible setting; only a blank page prints unless the layer's eye icon is toggled to Visible.
