Abstract

A method is described to permit page layout definitions, e.g., first chapter page, recto page, verso page, etc., to be identified and made available to Document and Page Composition products using Page Models from which several page images can be created to view or print data. The Page Model function is a feature of the Mixed Object Document Content Architecture (MO:DCA) to provide page image generation based on the amount of available data to be imaged rather than the number of composed pages in a MO:DCA data stream. Fig. 1 illustrates this concept. The benefits of this function over the existing methods are as follows: 1. The document does not have to be paginated before it can be imaged. 2.

Page Model for DOCUMENT Processing

A method is described to permit page layout definitions, e.g., first chapter page, recto page, verso page, etc., to be identified and made available to Document and Page Composition products using Page Models from which several page images can be created to view or print data. The Page Model function is a feature of the Mixed Object Document Content Architecture (MO:DCA) to provide page image generation based on the amount of available data to be imaged rather than the number of composed pages in a MO:DCA data stream. Fig. 1 illustrates this concept. The benefits of this function over the existing methods are as follows: 1. The document does not have to be paginated before it can be

imaged.

2. Objects that provide data for two or more page images do not

have to be broken into two or more smaller objects whose data

is contained within two or more composed pages.

3. Different page layouts can be used to produce two or more page

images for one data group (e.g., one object).

4. Page layouts can be automatically or explicitly selected. A page model is a set of linked Page Descriptor structured fields, as shown in Fig. 2. The first descriptor for the first page image is identified by a Map Page structured field. The next descriptor for the next page image is pointed to by the descriptor used for the current page image. The page model in Fig. 2 contains three descriptors. For this example, it is assumed that descriptor A defines the page layout for the first page of a chapter, descriptor B defines the page layout for the left-hand pages of a chapter, and descriptor C defines the page layout for the right-hand pages of a chapter. Map Page selects descriptor A; therefore, descriptor A defines the page layout of the first page image for the data provided by the object contained in data group D. Note that Map Page also selects a data group, establishing an explicit relationship between a page model and the data to be imaged. When data group D is imaged, the order of its imaged pages is first chapter page, followed by a left-hand page, followed by a right-hand page. Page imaging continues, alternating between left-hand and right- hand pages until the end of the data group. In effect, the number of

page images created for the data group is dependent on the amount of data within the data group. For example, if more data is added to the data group, then more page images may be generated when next the d...
