信息技术 图像处理与交换（IPI）功能规范 第5部分：基本图像交换格式（BIIF）

[中文适用范围]： 本文件建立了基本图像交换格式（BIIF）的规范。本文件为应用之间交换图像和图像相关数据的互操作性提供了基础。它还详细描述了格式的总体结构，以及BIIF定义的所有字段的有效数据和格式规范。附录C包含BIIF的模型配置文件表，以协助配置文件开发。本文件的范围和应用领域包括支持商业和政府图像、程序员成像内核系统（PIKS）数据以及其他图像技术领域的能力，按该优先级顺序。本文件为图像、符号和文本提供了数据格式容器，以及包含图像相关支持数据的机制。本文件：提供了一种方式，使不同的应用可以共享图像和相关信息；允许应用向具有不同需求或能力的用户交换全面信息，允许每个用户仅选择与其需求和能力相对应的数据项；最小化数据的预处理和后处理；最小化格式化开销，特别是对于那些仅交换少量数据的应用和带宽受限的系统；提供了一种机制（可传输文件结构，TFS）来交换PIKS图像和图像相关对象；提供可扩展性以适应未来的数据，包括对象。 [外文原描述]： This document establishes the specification of the Basic image interchange format (BIIF). This document provides a foundation for interoperability in the interchange of imagery and imagery-related data among applications. It also provides a detailed description of the overall structure of the format, as well as specification of the valid data and format for all fields defined with BIIF. Annex C contains a Model Profile of BIIF in tables to assist in profile development. The scope and field of application of this document includes the capability to perpetuate a proven interchange capability in support of commercial and government imagery, Programmer’s Imaging Kernel System (PIKS) data, and other imagery technology domains in that priority order. This document provides a data format container for image, symbol, and text, along with a mechanism for including image-related support data. This document: — provides a means whereby diverse applications can share imagery and associated information; — allows an application to exchange comprehensive information to users with diverse needs or capabilities, allowing each user to select only those data items that correspond to their needs and capabilities; — minimizes preprocessing and postprocessing of data; — minimizes formatting overhead, particularly for those applications exchanging only a small amount of data and for bandwidth-limited systems; — provides a mechanism (Transportable File Structure, TFS) to interchange PIKS image and image-related objects; — provides extensibility to accommodate future data, including objects.
