Security considerations: Page Definitions are part of AFP Line Data, which is an architected specification of final-form presentation data. It is not a programming language, does not contain any file operators, and therefore cannot corrupt a receiver's file system or programming environment. It does not allow executable content or calls to external applications. The format does not provide integrity or privacy protection in itself. If privacy or integrity protection is needed it must be provided by external means. Interoperability considerations: none Published specification: As part of "AFP Programming Guide and Line Data Reference", AFP Consortium publication AFPC-0010-05. Page Definitions are described here with their synonym "Page Map". Link: https://www.afpconsortium.org/uploads/1/1/8/4/118458708/linedata-reference-05.pdf Application usage: A Page Definition is an AFP Line Data resource object. A presentation services program uses Page Definitions to map the line data produced by application programs. Used in Advanced Function Presentation (AFP) generators and consumers. A wide variety of applications are created by members of the AFP Consortium and other parties. Fragment Identifier Considerations: N/A Restrictions in Usage: This format is mostly used in applications around high speed transactional printing. Additional information: Deprecated alias names for this type: N/A Magic number(s): As any other AFP object, Page Definitions are enclosed with a "Begin" and an "End" structured field. A Page Definition starts with the sequence: 0xD3A8CB - Begin Page Map (BPM) Structured Field and it ends with the sequence: 0xD3A9CB - End Page Map (EPM) Structured Field File extension(s): N/A Macintosh File Type Code(s): N/A Object Identifiers: none Intended usage: Limited use Form Definitions as part of AFP Line Data is application output to be presented on screen or paper.
