Editing movie clip symbols with 9-slice scaling
By default, slice guides are placed at 25% (or 1/4) of the symbol's width and height from the edge of
the symbol. When you are in symbol-editing mode, the slice guides appear with dotted lines
superimposed on the symbol on the main Stage. The guides do not appear when the symbol is in
edit-in-place mode. Slice guides don't snap when you drag them in the workspace.
To enable 9-slice scaling for an existing movie clip symbol:
1. With the source document open, select Window > Library to display the Library panel.
2. Select a movie clip, button, or graphic symbol in the Library panel.
3. Select Properties from the Library options menu.
4. Select the Enable Guides for 9-slice Scaling check box.
The slice guides are superimposed on the symbol on the Stage.
To edit a movie clip symbol using 9-slice scaling:
1. Enter symbol-editing mode by doing one of the following:
o Select an instance of the symbol on the Stage and right-click (Windows) or Control-
click (Macintosh), and select Edit from the context menu.
o Select the symbol in the Library and right-click (Windows) or Control-click
(Macintosh), and select Edit from the context menu.
o Double-click the symbol in the Library.
