Compression scheme used in the HD Photo (also known as WM Photo) image file format. HD Photo delivers a lightweight, high performance algorithm with a small memory footprint that enables practical, in-device encoding and decoding. It delivers compression quality comparable with JPEG-2000 and more than twice the quality of JPEG.

You need ImageGear.WPF Namespace to use this compression.
