标准摘要
[中文适用范围]: 本文件 specifies the Multi-Image Application Format (MIAF),其中包含编码图像、图像组和序列以及它们的元数据,并嵌入在高效图像文件(HEIF)格式中。该文件构建于 HEIF 规范之上,定义了以下内容:——对 ISO/IEC 23008-12(HEIF)规范的一组附加约束条件,以简化其文件格式选项;——特定的 alpha 平面格式;——一组支持编码格式的具体配置文件和级别;——一组具体元数据格式;——一组品牌,包括应用程序品牌,表示符合特定配置文件;——扩展 MIAF 格式以支持其他编码格式、配置文件、级别和元数据的一组规则。该文件还定义了 MIAF 阅读器和 MIAF 渲染器的规范性行为。MIAF 规格书特意编写为可扩展的,并允许向前兼容。该格式也容许其他数据的存在,例如编码格式、元数据和其他派生图像。 [外文原描述]: This document specifies the Multi-Image Application Format (MIAF), which contains coded images, groups and sequences of images along with their metadata and the information about their relations to each other, all embedded in the High Efficiency Image File (HEIF) format. This document builds on the HEIF specification and defines the following: — a set of additional constraints on ISO/IEC 23008-12 (HEIF) specification, to simplify its file format options; — specific alpha plane formats; — a set of specific profiles and levels for the supported coding formats; — a set of specific metadata formats; — a set of brands, including application brands indicating conformance with specific profiles; — a set of rules for extending MIAF format to support additional coding formats, profiles, levels and metadata. This document also defines the normative behaviour for a MIAF reader and MIAF renderer. The MIAF specification is intentionally written to be extensible, and to allow for forward compatibility. The format is also permissive of the presence of other data, such as coding formats, metadata, and derived images.
