JPEG-XR lib - command line apps

JPEG XR is an approved ISO/IEC International standard (its official designation is ISO/IEC 29199-2).

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

For web developers, JPEG XR has a large number of interesting features, see the table below. Some of these are big advantages over other image formats like JPEG, PNG, OpenEXR, and TIFF.

 - Better Compression (40% smaller than JPEG)
 - Lossless Mode (better compression than PNG)
 - 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.)
