 JPEG XR started its life in Microsoft Research. It publicly first appeared as
 the HD Photo format in Windows Vista.

  - Alpha Channel (compress color lossy and alpha losslessly)
  - Extended Bitdepth (supports 8-, 16-, and 32-bit/channel)
  - Progressive Decode
  - Advanced Decoding Features (tile-based layout, for efficient
    region-of-interest access.)
