Note: The Advanced button isn’t available if you choose Label Only from the Layout menu.
4 Select an option from the When To Scale menu:
Always Scales the icon as defined regardless of its size in relation to the button size.
Never Preserves the original size of the icon; the button border crops the icon if it doesn’t fit. If Never is selected,
scale options aren’t available.
Icon Is Too Big Scales the icon as defined only if it is larger than the button.
Icon Is Too Small Scales the icon as defined only if it is smaller than the button.
5 From the Scale menu, select whether to scale the icon proportionally. If the icon is scaled nonproportionally, it may
be skewed.
6 To make sure that either the top and bottom or left and right sides of the icon are flush against the button edges,
select Fit To Bounds.
7 To define where the icon is placed inside the button, drag the slider arrows. Icon placement is defined according to
the percentage of space preserved between the icon and the left field boundary, and between the icon and the bottom
field boundary. The default setting (50, 50) places the icon in the middle of a field. You can click Reset at any time
to revert to the default placement setting.
8 Click OK, and then click Close.
Hide an Acrobat button except during rollover
In some cases, you may want the button area to be invisible until the pointer moves over it. By alternately showing and
hiding a button, you can create interesting visual effects in a document. For example, when you move a pointer over a
city on a map, a detail map of the city could be displayed, and the detail map could disappear when the pointer moves
away from the city.

previewed image as the button.
