This document:

      specifies extended decoding processes for converting compressed image data to reconstructed image data;

      specifies an extended codestream syntax containing information for interpreting the compressed image data;

      specifies an extended file format;

      specifies a container to store image metadata;

      defines a standard set of image metadata;

      provides guidance on extended encoding processes for converting source image data to compressed image data;

      provides guidance on how to implement these processes in practice.
