适用范围：This part of ISO/IEC ISP 15124 specifies an interchange format suitable for transfer of structured documents between equipment designed for raster processing. The documents supported by ISO/IEC ISP 15124 are based on a paradigm of an electronic engineering drawing or illustration. Such documents contain one or more pages. Each page consists of a base image in the form of a bi-tonal raster graphics, character, or geometric graphics content. This base image may be further annotated with character, raster graphics or geometric graphics content. These latter content portions serve to provide revision control for the engineering drawing or illustration. There is no restriction on the minimum size of the base image. ISO/IEC ISP IS 124 allows large format raster documents to be interchanged in a formatted form in accordance with ISO/IEC 8613. It is assumed that, when negotiation is performed by the service using this part of ISO/IEC ISP IS 124, all non-basic values are subject to negotiation. This pan of ISO/IEC ISP 15124 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 part of ISO/IEC ISP IS 124 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. There are two DAP object identifiers supporting this part of ISO/IEC ISP 15124 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.
