Types of plug-ins

Plug-ins are notified by Illustrator when they have just been loaded or are about to be unloaded,
permitting them to restore or save any state information.

Types of plug-ins

This section describes the different types of Illustrator plug-ins you can create. A single plug-in file can
contain multiple plug-in types. For example, a shape creation plug-in may implement several plug-in
filters and a plug-in tool. Plug-in types are listed in the following table and described more fully after the
