title: Free JPEG2000 Library or SDK for de-compression
body: <p>I have written code to compress and decompress image files using a proprietary SDK for transmission from an aircraft via satellite. Unfortunately a license must be purchased for decompression as well as compression.  Until now my applications have been mostly used in-house so I can keep track of the licenses and distribution.  Now I need to provide the applications for outsiders and I can neither control distribution nor want to pay for the licenses.</p>
  
  <p>Does anyone know of free de-compression programs, SDKs, or libraries?  I program in C++ for Windows NT, 2000, XP.  </p>
  
  <p>My image files are raw data, monochrome, with 16bit unsigned pixels and the compression that is used is lossless or very mildly lossy.</p>
