Template:Short description Template:Infobox software

JasPer is a computer software project to create a reference implementation of the codec specified in the JPEG-2000 Part-1 standard (i.e. ISO/IEC 15444-1) - started in 1997 at Image Power Inc. and at the University of British Columbia.<ref>Template:Cite web</ref> It consists of a C library and some sample applications useful for testing the codec.

The copyright owner began licensing the code to the public under an MIT License-style license in 2004 in response to requests from the open-source community. Template:As of JasPer operated as a component of many software projects, both free and proprietary, including (but not limited to) netpbm (as of release 10.12), ImageMagick and KDE<ref name="kde3">Template:Cite web</ref> (as of version 3.2).<ref name="jasper">Template:Cite web</ref><ref name="xnview">Template:Cite web</ref> Template:As of the GEGL graphics library supported JasPer in its latest Git versions.<ref name="gegl">Template:Cite web</ref>

In a series of objective JPEG-2000-compression quality tests conducted in 2004, "JasPer was the best codec, closely followed by IrfanView and Kakadu".<ref> Template:Cite conference </ref> However, Jasper remains one of the slowest implementations of the JPEG-2000 codec, as it was designed for reference, not performance.Template:Original research inline

Etymology
