scope:

This is the definition of a specification for an Office Document Architecture (ODA) Document Application Profile (DAP) named ODA Raster DAP. This DAP is suitable for interchanging documents in formatted form. The documents contain only raster graphics images. There are two DAP object identifiers supporting this DAP with the only difference being in the encoding of the data stream. One uses the ASN.1 based ODIF encoding. The other uses the SGML/SDIF based ODL encoding. When this document refers to this profile, it is referring to this specification regardless of which DAP identifier may be selected to create the data stream.

This DAP has been prepared by the ODA Special Interest Group (SIG) of the Open Systems Environment Implementors' Workshop (OIW). The DAP is defined in accordance with ISO 8613-1 and follows the standardized proforma and notation defined in ISO 8613-1 Annex F. The DAP is based on ODA as defined in ISO 8613 and the Tiled Raster Graphics Addendum to ISO 8613, Part 7.

This DAP specifies an interchange format suitable for transfer of structured documents between equipment designed for raster processing. The documents supported by this DAP are based on a paradigm of an electronic engineering drawing or illustration. Such documents contain one or more pages. Each page consists of an image in the form of a bi-tonal raster graphics content. There is no restriction on the minimum size of the image.

This document defines a DAP that allows large format raster documents to be interchanged in a formatted form in accordance with ISO 8613.

It is assumed that, when negotiation is performed by the service using this DAP, all non-basic values am subject to negotiation.

This DAP is independent of the processes carried out in an end system to create, edit, or reproduce raster documents. It is also independent of the means to transfer the document which, for example, may be by means of communication links or exchanged storage media.

The features of a document that can be interchanged using this DAP fall into the following categories:

a. Page format features - these concern how the layout of each page of a document will appear when reproduced.

b. Raster graphics layout and imaging features - these concern how the document content will appear within pages of the reproduced document.

c. Raster graphics coding - these concern the raster graphics representations and control functions that make up the document raster graphics content.
