JPEG-XR lib - libraries
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.)
