Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium (W3C) since 1999. SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted, and compressed. As XML files, SVG images can be created and edited with any text editor, but are more often created with drawing software. All major modern web browsers—including Mozilla Firefox, Internet Explorer, Google Chrome, Opera, and Safari—have at least some degree of SVG rendering support. ==Overview== SVG has been in development since 1999 by a group of companies within the W3C after the competing standards Precision Graphics Markup Language (PGML, developed from Adobe's PostScript) and Vector Markup Language (VML, developed from Microsoft's RTF) were submitted to W3C in 1998. SVG drew on experience from the designs of both those formats. SVG allows three types of graphic objects: vector graphics, raster graphics, and text. Graphical objects, including PNG and JPEG raster images, can be grouped, styled, transformed, and composited into previously rendered objects. SVG does not directly support z-indices that separate drawing order from document order for overlapping objects, unlike some other vector markup languages like VML. Text can be in any XML namespace suitable to the application, which enhances search ability and accessibility of the SVG graphics. The feature set includes nested transformations, clipping paths, alpha masks, filter effects, template objects, and extensibility. Since 2001, the SVG specification has been updated to version 1.1. The SVG Mobile Recommendation introduced two simplified ''profiles'' of SVG 1.1, SVG Basic and SVG Tiny, meant for devices with reduced computational and display capabilities. An enhanced version of SVG Tiny, called SVG Tiny 1.2, later became an autonomous Recommendation.〔 Work is currently in progress on SVG 2, which incorporates several new features in addition to those of SVG 1.1 and SVG Tiny 1.2. 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「Scalable Vector Graphics」の詳細全文を読む スポンサード リンク
