Path Item, Sub Path Item, and Path Point classes
The
Path
Item
class represents information about a drawing object, such as the outline of a shape, or a
curved line. The
Sub
Path
Item
class is contained in the
Path
Item
class, and provides the actual geometry
of the shape. The
Path
Point
class contains information about each point in a sub path. See
“Using the
PathItem object” on page 49
.
Preferences class
The
Preferences
class allows you to access and set the user preference settings. See
“Working with
document preferences” on page 61
.
Notifier class
The
Notifier
object ties an event to a script. For example, if you would like Photoshop to automatically
create a new document when you open the application, you could tie a script that creates a
Document
object to an
Open
Application
event. For more information on notifiers, see
