SWF is also sometimes used for creating animated display graphics and menus for DVD movies, and television commercials.

SWF is currently the dominant format for displaying animated vector graphics on the web, far exceeding the W3C open standard SVG, which has met with problems over competing implementations. An open standard is a Standard that is publicly available and has various rights to use associated with it

On 1 May 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. The Gnash project aims to create a free player and Browser plugin for the Adobe Flash file format and replace the Proprietary software niche [3]

Description

Originally limited to presenting vector based objects and images in a simple sequential manner, the newer versions of the format allow audio, video and many different possible forms of interaction with the end user. Once created, SWF files can be played by the Adobe Flash Player, working either as a browser plugin or as a standalone player. The Adobe Flash Player is a widely distributed proprietary multimedia and application player created by Macromedia and now developed and distributed by Adobe SWF files can also be encapsulated with the player, creating a self-running SWF movie called a "projector".

The file format was first created by FutureWave, a small company later acquired by Macromedia with one primary objective: to create small files for displaying entertaining animations. [4] The idea was to have a format which could be reused by a player running on any system and which would work with slower network connection.

Plugins to play SWF files in web browsers are available from Adobe for most desktop operating systems, including Microsoft Windows, Apple Mac, and Linux on the x86 architecture. A web browser is a software application which enables a user to display and interact with text images videos music games and other information typically located on a Microsoft Windows is a series of Software Operating systems and Graphical user interfaces produced by Microsoft.

Licensing

A full specification of SWF is available. Until May 1, 2008, it was not an open format, as implementing software that plays the format was disallowed by the specification's license[6]. An open format is a published specification for storing digital data usually maintained by a Standards organization, which basically can be used and implemented by anyone On that date, however, as part of its Open Screen Project, Adobe dropped all such restrictions on the SWF and FLV formats. [7] Implementing software which creates SWF files has always been permitted, on the condition that the resulting files render "error free in the latest publicly available version of Adobe Flash Player. "[8] The Wikimedia Foundation decided to partner with Kaltura[9] which offers Flash-based video-editing solutions. The Wikimedia Foundation Inc is a Non-profit charitable organization headquartered in San Francisco, California, United States, Kaltura is a Software company based in New York which was founded in 2006

An open source SWF player called Gnash is currently being developed by GNU under the GNU General Public License (GPL). Open source is a development methodology which offers practical accessibility to a product's source (goods and knowledge The Gnash project aims to create a free player and Browser plugin for the Adobe Flash file format and replace the Proprietary software niche GNU ( pronounced) is a computer Operating system composed entirely of Free software.
