SWF ( ) is an abbreviation for ''small web format'', an Adobe Flash file format used for multimedia, vector graphics and ActionScript.〔(Open Screen Project )〕 Originating with FutureWave Software, then transferred to Macromedia, and then coming under the control of Adobe, SWF files can contain animations or applets of varying degrees of interactivity and function. It may also be used for programs, commonly browser games, using ActionScript. SWF files can be generated from within several Adobe products including Flash, Flash Builder (an IDE) and After Effects, as well as through MXMLC, a command line application compiler which is part of the freely available Flex SDK. Although Adobe Illustrator can generate SWF format files through its "export" function, it cannot open or edit them. Other than Adobe products, SWFs can be built with open source Motion-Twin ActionScript 2 Compiler (MTASC), the open source Ming library and the free software suite SWFTools. There are also various third party programs that can produce files in this format, such as Multimedia Fusion 2, Captivate and SWiSH Max. Originally, the term SWF was used as an abbreviation for ''ShockWave Flash''. This usage was changed to the backronym ''Small Web Format'' to eliminate confusion with a different technology, Shockwave, from which SWF was derived.〔(【引用サイトリンク】title=SWF Definition from PC Magazine Encyclopedia )〕 == History == The small company FutureWave Software originally defined the file format with one primary objective: to create small files for displaying entertaining animations. The idea involved a format which player software could run on any system and which would work with slower network connections. FutureWave released FutureSplash Animator in May 1996. In December 1996 Macromedia acquired FutureWave and FutureSplash Animator became Macromedia Flash 1.0. The original naming of SWF came out of Macromedia's desire to capitalize on the well-known Macromedia Shockwave brand; Macromedia Director produced Shockwave files for the end user, so the files created by their newer Flash product tried to capitalize on the already established brand. As Flash became more popular than Shockwave itself, this branding decision became more of a liability, so the format started to be referred to as simply SWF.〔 Adobe acquired Macromedia in 2005. On May 1, 2008, Adobe dropped its licensing restrictions on the SWF format specifications, as part of the Open Screen Project. However, Rob Savoye, a member of the Gnash development team, has pointed to some parts of the Flash format which remain closed. On July 1, 2008, Adobe released code which allowed the Google and Yahoo search-engines to crawl and index SWF files.〔 (Streamingmedia.com: Google and Yahoo Roll out Flash Search )〕 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「SWF」の詳細全文を読む スポンサード リンク
