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.[1] 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. As of 2011[update]Template:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters". 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[2] (as of version 3.2).[3][4] As of 22 June 2010[update]Template:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters". the GEGL graphics library supported JasPer in its latest Git versions.[5]
In a series of objective JPEG-2000-compression quality tests conducted in 2004, "JasPer was the best codec, closely followed by IrfanView and Kakadu".[6] However, Jasper remains one of the slowest implementations of the JPEG-2000 codec, as it was designed for reference, not performance.Script error: No such module "Unsubst".
Etymology
The name "JasPer" has simultaneous connotations with Canada's Jasper National Park, with the semi-precious gemstone, jasper, and with "JP" as an abbreviation of the JPEG-2000 standard.[7]
