The library in a Flash Professional document stores media assets that you create in the Flash Professional authoring environment or import to use in the document. You can create vector artwork or text directly in Flash Professional; import vector artwork, bitmaps, video, and sound; and create symbols. A symbol is a graphic, a button, a movie clip, or text that you create once and can reuse multiple times. You can also use ActionScript to add media content to a document dynamically.
The library also contains any components that you have added to your document. Components can be either compiled clips or MovieClip based components.
You can open the library of any Flash Professional document while you are working in Flash Professional, to make the library items from that file available for the current document.
You can create permanent libraries in your Flash Professional application that are available whenever you start Flash Professional. Flash Professional also includes several sample libraries containing buttons, graphics, movie clips, and sounds.
You can export library assets as a SWF file to a URL to create a runtime-shared library. This lets you link to the library assets from Flash Professional documents that import symbols using runtime sharing.
The Library panel (Window > Library) displays a scroll list with the names of all items in the library, which lets you view and organize these elements as you work. An icon next to an item’s name in the Library panel indicates the item’s file type.
note: (Flash Professional CC and later versions only) Dragging objects from Stage to the Library panel to convert to a Symbol is deprecated, and will not be functional with Flash Professional CC.
note: (Flash Professional CC and later versions only) Dragging objects on to the Stage across two undocked documents is deprecated, and will not be functional with Flash Professional CC.
