Viewing Layers
You can control your view of an image in the document window by changing layer
visibility settings. This is helpful in both compositing an image and applying effects.
You can hide one layer to gain better visibility of the layer below it. Or, you can set up
different states of an image to create rollover effects for use on the Web. For more
information about creating rollovers, refer to “Creating Rollovers from Image Slices” in
the Help.
Use layer visibility settings to create different states of an image. In the example on the left, the
layers containing the background are hidden; in the example on the right, the layers containing
the background are visible.
Layer visibility settings stay active when you print or save documents to certain file
formats. In other words, the content of hidden layers does not print and is not saved.
However, saving a document in RIF or PSD format preserves hidden layers as part of
the document. Refer to “Saving Files That Contain Layers” on page 51 for more
information about how layers are saved in different file formats.
To show or hide a layer or the canvas
• On the Layers palette, click the eye icon next to the layer name or the canvas.
When the eye is shut , the layer is hidden in the document window. When the
eye is open , the layer is visible in the document window.
