Apple DVD Studio Pro 4 - Manual (Page 110)

Important: If you use this layer’s opacity to create pseudo-soft or anti-aliased edges or
to have multiple highlight colors appear at once, you can only use the shape in menus
set to use the advanced grayscale overlay method. In these cases, the opacity values
map to the overlay colors as follows: 100% maps to black, 99% to 67% maps to dark
gray, 66% to 17% maps to light gray, and 16% to 0% maps to white.
• Fourth layer: Contains the shape’s icon, which appears in the Shapes tab in the Palette
and shape selector in the Button and Drop Zone Inspectors. This is an optional
layer—the second layer provides this function if this layer is not present. The
disadvantage of using the second layer is that often the shape alone does not provide
a good indication of what the button will look like once you assign an asset to it.
DVD Studio Pro uses the RGB values for the icon.
Note: Do not include the fourth layer in the file unless you are adding a graphic to be
used as the thumbnail. Adding an empty fourth layer results in a shape that you cannot
use in DVD Studio Pro.
Setting a Shape’s Opacity
DVD Studio Pro does not use the opacity settings you can apply to the layers within
Photoshop. As a result, you cannot use the second layer’s opacity setting to control the
transparency of the shape’s visible graphic. As an alternative, you can use Photoshop’s
merge capability to get the desired effect.
To set a shape’s opacity
1 Create the shape in Photoshop as usual.
It’s a good idea to save the shape at this point so that you can go back to it if you later
need to adjust the opacity or content.
2 Set the opacity for the second layer (the shape’s visible graphic).
3 Add a new layer to the graphic, and place it below the second layer. (It becomes the
second layer, and the second layer becomes the third layer.)
