CHAPTER 2: Photoshop Scripting Basics Photoshop Object Model 14 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 "Using Notifier objects" on page 48. Count Item class The Count Item object provides scripting support for the Count Tool. Color Sampler class The Color Sampler object provides scripting support for the Color Sampler Tool. Measurement Scale class The Measurement Scale object provides scripting support for the new Measurement Scale feature that allows you to set a scale for your document.
