Customizing button displays
A button can have a label, an icon, or both. You can change how the button appears in each mouse state (Up, Down, and
Rollover). For example, you could create a button that has a "Home" label until the pointer is moved over the button,
when it might have a "Click to return to Home page" label.
Button layouts A. Label only B. Icon only C. Icon top, label bottom D. Label top, icon bottom E. Icon left, label right F. Label
left, icon right G. Label over icon
You can make button icons from any file format that Acrobat can display, including PDF, JPEG, GIF, and other image
formats. For whichever format you select, the entire page is used, so if you want to use only a portion of a page as an
icon, you need to crop the image or page before carrying out this procedure. The smallest allowable PDF page size is 1-
by-1 inch. If you want the icon to appear smaller than 1-by-1 inch, scale it to fit the size of the box drawn with the
button tool. Clicking Advanced on the Options tab of the Button Properties dialog box lets you determine how a button
icon is scaled to fit inside a button.
To specify button display properties:
1. In the Advanced Editing toolbar, select the Button tool .
2. Double-click an existing button, and then click the Options tab in the Button Properties dialog box.
3. For Layout, choose the type of label display you want. (For information on scaling button icons, see the next procedure.)
4. For Behavior, specify the display of the button when clicked:
● None keeps the appearance of the button the same.
● Push lets you define different appearances for the Up, Down, and Rollover states of the mouse. Select an option under
State, and then specify a label or icon option. Up determines what the button looks like when the mouse button isn't
clicked. Down determines what the button looks like when the mouse is clicked on the button, but before it's released.
Rollover determines what the button looks like when the pointer is held over the button. (See Showing and hiding image
buttons.)
● Outline highlights the button border.
● Invert reverses the dark and light shades of the button.
5. To define the label or icon that appears on the button, do the following:
● If a label option is selected from the Layout menu, type the text in the Label box.
● If an icon option is selected from the Layout menu, click Choose Icon, and then click Browse. Select the file type from
the Objects of Type (Windows) or Show (Mac OS) menu, double-click the file name, and then click OK. (Click Clear to
remove the selected icon.)
6. Click Close to accept these display properties.
To scale and position button icons:
1. On the Advanced Editing toolbar, select the Button tool , and then double-click the button.
2. Click the Options tab, select one of the icon options from the Layout menu, and then click Advanced.
3. From the When to Scale menu, select one of the following options:
● Always scales the icon as defined regardless of its size in relation to the button size.
● Never preserves the icon's original size; 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.
4. From the Scale menu, select whether or not to scale the icon proportionally. If the icon is scaled nonproportionally, it
may be skewed.
5. 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.
6. 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.
7. Click OK, and then click Close.
