Converting an enhanced metafile into a chronologically independent object property list for conversion into a PDF document
Abstract:
An electronic paper file is generated from an enhanced metafile such that data may be converted from multiple applications with different data descriptions to a single electronic paper format having a particular data description. The enhanced metafile includes a series of individual records that provide a sequence of graphic instructions to render properties associated with objects in the document in an output format. The enhanced metafile is parsed into a series of state independent objects to generate an intermediary representation of the document. The objects and corresponding identifying information are temporarily stored in an object storage structure before using the objects to generate the electronic paper file. The object storage structure provides a stateless model of the enhanced metafile such that the objects may be randomly accessed and applied to any output format.
