In the field of computer software, JasPer - a 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. It consists of a C library and some sample applications useful for testing the codec. The license changed in early 2004 to an MIT License-style one, in response to requests from the open-source community. 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〔(【引用サイトリンク】title=KDE TechBase - Development/Architecture/KDE3/Imaging and Animation )〕 (as of version 3.2).〔(【引用サイトリンク】title=The JasPer Project Home Page )〕〔(【引用サイトリンク】title=XnView User Guide )〕 the GEGL graphics library supported JasPer in its latest Git versions.〔(【引用サイトリンク】title=The GEGL source code git repository )〕 In a series of objective JPEG-2000-compression quality tests conducted in 2004, "JasPer was the best codec, closely followed by IrfanView and Kakadu".〔 〕 However, Jasper remains one of the slowest implementations of the JPEG-2000 codec, as it was designed for reference, not performance. == 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.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「JasPer」の詳細全文を読む スポンサード リンク
