Abstract

A method is described which allows the data provided by one object to be assigned to one or more object areas on one or more page images. This function, called Object Area Linkage, is part of the Object Area Descriptor structured field of the Mixed Document Content Archi (Image Omitted) tecture (MO:DCA) to allow the data provided by an object to be assigned to one or more object areas (Fig. 1). Another function, called Object Area Format, specifies if data can be assigned to object areas that span page image and page model boundaries (Fig. 2). The benefits of this enhanced function for the assignment of data to an object area are: The data from on object can be assigned to selected object areas on one page image, on page images defined by one page model, or on page images defined by two or more page models.

Object Area Linkage and Format for DOCUMENT Processing Environments

A method is described which allows the data provided by one object to be assigned to one or more object areas on one or more page images. This function, called Object Area Linkage, is part of the Object Area Descriptor structured field of the Mixed Document Content Archi

tecture (MO:DCA) to allow the data provided by an object to be assigned to one or more object areas (Fig. 1). Another function, called Object Area Format, specifies if data can be assigned to object areas that span page image and page model boundaries (Fig. 2). The benefits of this enhanced function for the assignment of data to an object area are: The data from on object can be assigned to selected

object areas on one page image, on page images defined

by one page model, or on page images defined by two or

more page models. In MO:DCA an object area is defined by its Object Area Descriptor (OBD) structured field. Object Positioning (OBP) structured fields are used to position one or more object areas on one or more pages. Object Map (MRT, MIG, MBO, etc., for Map Revisable Text Object, Map Image Object, Map Graphics Object, etc., structured fields are used to position object data (text, image, graphics, etc.) in an object area. The positioning of object data in object areas has been enhanced by the addition of two parameters, Next Object Area Descriptor and Object Area Format Flags, in the Object Area Descriptor structured field.

The Next Object Area Descriptor parameter links object areas together to form a sequence of object areas to which object data can be assigned. The initial object area, to which the data from an object is assigned, is specified by a Map Object structured field which maps an object's data to the object area by referencing both the object that contains the data and the descriptor that defines the object area. The Next Object Area Area Descriptor parameter in the referenced descriptor can name another Object Area Descriptor structured field in which case there are at least two object areas for the page image to which object data from an object can be assigned in a sequential fashion. That is, the first portion of the object's data is assigned to the first object area and when that area is full, the next portion of the object's data is assigned to the next object area on the same page image, and so on. Before object area linkage was added to MO:DCA, the only way to assign object data to two object areas on the same page image was to

map the object to both areas. This approach had the drawback that only the first portion of the object's data would be assigned to both object areas. Therefore, objects had to be broken up into smaller objects to have all of the data assigned to object areas. The ability to link Object Area Descriptors through the Next Object Area Descriptor parameter avoids the necessity of having to bra...
