Military Specification: Requirements for Raster Graphics Representation in Binary

摘要

This specification is intended to be used by contracting agencies of the Department of Defense in the procurement of raster graphics data and raster graphics applications. The specification presents raster graphics requirements which are applicable to electronic storage and transmission of raster encoding of office document pages and large format engineering drawings. Raster graphics representation specified herein consists of two types. Type I or untiled raster graphics data has no document architecture and is represented by a single compressed data entity. Type II or tiled raster graphics has a document architecture conforming to ISO 8613 wherein the raster content consists of extensions to the ISO 8613-part 7 raster content architecture. The extensions are presented in the form of part 7 addenda and permit the encoding of layout content which is subdivided into tiles. Untiled raster graphics requirements are intended to be used in procuring data for systems that utilize untiled raster graphic representations. Examples of such systems include typical technical documentation systems and DSREDS/EDCARS used by the Army and Air Force. Tiled raster graphics requirements are intended to be used in procuring data for systems that utilize tiled raster graphics representations. Such representations are best applied in systems handling large format drawings typically associated with engineering design. (kr)
