scope:

This Recommendation | International Standard specifies a coding format, referred to as JPEG XR, which is designed primarily for continuous-tone photographic content. The main body of the text specifies the syntax and semantics of JPEG XR coded images and the associated decoding process. Annex A specifies a tag-based file storage format for the storage and interchange of such coded images. Annex B specifies profiles and levels, which determine conformance requirements for classes of encoders and decoders. Aspects of color imagery representations and color management are discussed in Annex C. The typical expected encoding process is described in Annex D.
