标准摘要
[中文适用范围]： 本文档规定了多图像应用程序格式 (MIAF)，其中包含编码图像、图像组和图像序列及其元数据和有关它们彼此关系的信息，所有这些都嵌入在高效图像文件 (HEIF) 格式中。本文档以 ISO/IEC 23008-12 (HEIF) 为基础，并规定了以下内容： — 一组对 ISO/IEC 23008-12 (HEIF) 的附加约束，以简化其文件格式选项； — 特定的 alpha 平面格式； — 一组用于支持编码格式的特定配置文件和级别； — 一组特定的元数据格式； — 一组品牌，包括表示符合特定配置文件的应用程序品牌； — 一组用于扩展 MIAF 格式以支持其他编码格式、配置文件、级别和元数据的规则。本文档还定义了 MIAF 阅读器和 MIAF 渲染器的规范行为。本文档 (MIAF) 旨在具有可扩展性，并允许向前兼容。该格式还允许存在其他数据，例如编码格式、元数据和派生图像。 [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 ISO/IEC 23008-12 (HEIF) and specifies the following: — a set of additional constraints on ISO/IEC 23008-12 (HEIF), 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. This document (MIAF) 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.
