Introduction JPEG XR (JPEG extended range) is a still-image compression standard and file format for continuous tone photographic images, based on technology originally developed and patented by Microsoft under the name HD Photo. It supports both lossy and lossless compression, and is the preferred image format for Ecma-388 Open XML Paper Specification documents. The DirectDraw Surface container file format (uses the filename extension DDS), is a Microsoft format for storing data compressed with the proprietary S3 Texture Compression (S3TC) algorithm, which can be decompressed in hardware by GPUs.
Technical details One file container format that can be used to store JPEG XR image data is specified in Annex A of the JPEG XR standard. It is a TIFF-like format using a table of Image File Directory (IFD) tags. A JPEG XR file contains image data, optional alpha channel data, metadata, optional XMP metadata stored as RDF/XML, and optional Exif metadata, in IFD tags. The DirectDraw Surface format is useful for storing graphical textures and cubic environment maps as a data file, both compressed and uncompressed. The Microsoft Windows file extension for this data format is '.dds'.
