But I'm glad to say that in IPP v4.1 (which is available right now) we significantly improve this sample. Now it supports encoding and decodingfor both lossless and lossy modes. There will be even more improvements in next version, IPP v5.0 beta which comes soon.</DIV> <DIV></DIV> <DIV>So, you can download IPP v4.1 libraries and samples from here</DIV> <DIV><A href="http://www.intel.com/software/products/ipp/" target="_blank">http://www.intel.com/software/products/ipp/</A></DIV> <DIV></DIV> <DIV>Regards,</DIV> <DIV> Vladimir</DIV><P>Message Edited by vdudnik on <SPAN class="date_text">04-22-2005</SPAN> <SPAN class="time_text">02:53 AM</SPAN></P> Fri, 22 Apr 2005 16:48:55 GMT Vladimir_Dudnik 2005-04-22T16:48:55Z https://community.intel.com/t5/Intel-Integrated-Performance/decompress-using-IPP/m-p/991923#M22446 <DIV></DIV> <DIV>I have compressed images (JPEG 2000 lossless).
