Using Format Objects and Collection Items to Format Pages
To support page-formatting features, your application needs to manipulate format objects and keep track of the number of times a format object is shared. Generally, you work with format objects when a user creates a new format, wants to share a format with additional pages in a single document, disposes of a page, or modifies a format that is shared by other pages in the same document. Because your application is responsible for associating format objects with the individual pages of a document, you need to save this association when a user saves a document.Your application can also manipulate format objects to support special formatting features. These features include associating form shapes with format objects, supporting page-specific halftone information in your application's documents, and copying format objects for use in multiple documents. QuickDraw GX also allows you to access information associated with a specific format object, such as its mapping and associated paper-type objects.
The following sections describe how to use page-formatting features.
