Scope

This part of ISO/IEC ISP 12064 specifies an interchange format suitable for transfer of structured documents between equipment designed for raster processing. The documents supported by this part of ISO/IEC ISP 12064 are based on a paradigm of an electronic engineering drawing or illustration. Such documents c ontain 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 part of ISO/IEC ISP 12064 allows large format raster documents to be interchanged in a formatted form in accordance with [ITU-T Rec. T.410 series /

ISO/IEC 8613].

It is assumed that, when negotiation is performed by the service using this part of ISO/IEC ISP 12064, all non-basic values are subject to negotiation.

This part of ISO/IEC ISP 12064 is independent of the processes carried o ut 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 part of ISO/IEC ISP 12064 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 reproduc ed document; (c) Raster graphics coding - these concern the raster graphics representations and control functions that make up the document raster graphics content.

There are two DAP object identifiers supporting this part of ISO/IEC ISP 12064 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 part of ISO/IEC ISP 12064, it is referring to this specification regardless of which DAP identifier may be selected to create the data stream. See more
