SVG images and their behaviors are defined in XML text files. This means that they can be, and. As XML files, SVG images can be created and edited with any, as well as with drawing software. All major modern —including, and —have. This image illustrates the difference between bitmap and vector images. The bitmap image is composed of a fixed set of pixels, while the vector image is composed of a fixed set of shapes. In the picture, scaling the bitmap reveals the pixels while scaling the vector image preserves the shapes.

SVG has been in development within the (W3C) since 1999, after six competing proposals for vector graphics languages had been submitted to the consortium during 1998. The early SVG Working Group decided not to develop any of the commercial submissions, but to create a new markup language that was informed by but not really based on any of them. SVG allows three types of graphic objects: shapes such as paths and outlines consisting of straight lines and curves, images, and text. Graphical objects can be grouped, styled, transformed and composited into previously objects.

The feature set includes nested, and template objects. SVG drawings can be and can include, defined in the SVG XML elements or via that accesses the SVG (DOM). SVG uses for styling and for scripting. Text, including, appearing in plain text within the SVG DOM enhances the of SVG graphics.

The SVG specification was updated to version 1.1 in 2011. There are two 'Mobile SVG Profiles,' SVG Tiny and SVG Basic, meant for with reduced computational and display capabilities. Scalable Vector Graphics 2 became a on 15 September 2016.

SVG 2 incorporates several new features in addition to those of SVG 1.1 and SVG Tiny 1.2. Printing Though the SVG Specification primarily focuses on, its design includes the basic capabilities of a like Adobe's. It contains provisions for rich graphics, and is compatible with for styling purposes. SVG has the information needed to place each glyph and image in a chosen location on a printed page. Scripting and animation. Main article: SVG drawings can be dynamic and interactive. Time-based modifications to the elements can be described in, or can be programmed in a (e.g.

The W3C explicitly recommends SMIL as the standard for animation in SVG. A rich set of such as onmouseover and onclick can be assigned to any SVG graphical object. Compression SVG images, being XML, contain many repeated fragments of text, so they are well suited for algorithms. When an SVG image has been compressed with the industry standard algorithm, it is referred to as an 'SVGZ' image and uses the corresponding.svgz filename extension. Conforming SVG 1.1 viewers will display compressed images. An SVGZ file is typically 20 to 50 percent of the original size. W3C provides SVGZ files to test for conformance.

Development history SVG was developed by the W3C starting in 1998, after six competing vector graphics submissions were received that year:. Web Schematics, from CCLRC. PGML, from Adobe, IBM, Netscape, and Sun. VML, by Autodesk, Hewlett-Packard, Macromedia, and Microsoft. Hyper Graphics Markup Language, by Orange, PCSL, and PRP. WebCGM, from Boeing, CCLRC, Inso, JISC, and Xerox. DrawML, from Excosoft The working group was chaired at the time by of the W3C.

Version 1.x. SVG 1.0 became a on 4 September 2001. SVG 1.1 became a W3C Recommendation on 14 January 2003. The SVG 1.1 specification is modularized in order to allow subsets to be defined as profiles.

Apart from this, there is very little difference between SVG 1.1 and SVG 1.0. and (the Mobile SVG Profiles) became W3C Recommendations on 14 January 2003.

These are described as profiles of SVG 1.1. SVG Tiny 1.2 became a W3C Recommendation on 22 December 2008. It was initially drafted as a profile of the planned SVG Full 1.2 (which has since been dropped in favor of SVG 2), but was later refactored as a standalone specification. SVG 1.1 Second Edition, which includes all the errata and clarifications, but no new features to the original SVG 1.1 was released on 16 August 2011. Version 2.x. SVG 2 will completely rework draft 1.2, with more integration with new web features such as CSS, HTML5, and.

Mobile profiles Because of industry demand, two mobile profiles were introduced with SVG 1.1: SVG Tiny (SVGT) and SVG Basic (SVGB). These are subsets of the full SVG standard, mainly intended for with limited capabilities. In particular, SVG Tiny was defined for highly restricted mobile devices such as; it does not support styling or scripting.

SVG Basic was defined for higher-level mobile devices, such as. In 2003, the, an international telecommunications standards group, adopted SVG Tiny as the mandatory vector graphics media format for next-generation phones. SVGT is the required vector graphics format and support of SVGB is optional for (MMS) and Packet-switched Streaming Service. It was later added as required format for vector graphics in 3GPP (IMS).

Differences from non-mobile SVG Neither mobile profile includes support for the full Document Object Model (DOM), while only SVG Basic has optional support for scripting, but because they are fully compatible subsets of the full standard, most SVG graphics can still be rendered by devices which only support the mobile profiles. SVGT 1.2 adds a microDOM (μDOM), styling and scripting. Related work The standard - Lightweight Application Scene Representation (LASeR) and Simple Aggregation Format (SAF) is based on SVG Tiny. It was developed by (/SC29/WG11) and published as ISO/IEC 144.

SVG capabilities are enhanced in MPEG-4 Part 20 with key features for mobile services, such as dynamic updates, binary encoding, state-of-art font representation. SVG was also accommodated in, in the - a textual representation of the MPEG-4 multimedia content using.

Functionality The SVG 1.1 specification defines 14 functional areas or feature sets: Paths Simple or compound shape outlines are drawn with curved or straight lines that can be filled in, outlined, or used as a. Paths have a compact coding. For example, M (for “move to”) precedes initial numeric x and y, and L (for “line to”) precedes a point to which a line should be drawn. Further command letters ( C, S, Q, T, and A) precede data that is used to draw various and curves. Z is used to close a path.

In all cases, absolute coordinates follow capital letter commands and relative coordinates are used after the equivalent lower-case letters. Basic shapes Straight-line paths and paths made up of a series of connected straight-line segments (polylines), as well as closed polygons, circles, and ellipses can be drawn. Rectangles and round-cornered rectangles are also standard elements. Text Unicode character text included in an SVG file is expressed as character data.

Many visual effects are possible, and the SVG specification automatically handles bidirectional text (for composing a combination of English and Arabic text, for example), vertical text (as Chinese was historically written) and characters along a curved path (such as the text around the edge of the ). Painting SVG shapes can be filled and/or outlined (painted with a color, a gradient, or a pattern). Fills may be opaque, or have any degree of transparency. 'Markers' are line-end features, such as arrowheads, or symbols that can appear at the vertices of a polygon.

Color Colors can be applied to all visible SVG elements, either directly or via fill, stroke, and other properties. Colors are specified in the same way as in, i.e. Using names like black or blue, in such as #2f0 or #22ff00, in decimal like rgb(255,255,127), or as percentages of the form rgb(100%,100%,50%).

Gradients and patterns SVG shapes can be filled or outlined with solid colors as above, or with color gradients or with repeating patterns. Color gradients can be linear or radial (circular), and can involve any number of colors as well as repeats. Opacity gradients can also be specified.

Patterns are based on predefined raster or vector graphic objects, which can be repeated in x and/or y directions. Gradients and patterns can be animated and scripted. Since 2008, there has been discussion among professional users of SVG that either or preferably could usefully be added to the SVG specification. It is said that a 'simple representation using diffusion curves is capable of representing even very subtle shading effects' and that 'Diffusion curve images are comparable both in quality and coding efficiency with gradient meshes, but are simpler to create (according to several artists who have used both tools), and can be captured from bitmaps fully automatically.' The current draft of SVG 2 includes gradient meshes.

Clipping, masking and compositing Graphic elements, including text, paths, basic shapes and combinations of these, can be used as outlines to define both inside and outside regions that can be painted (with colors, gradients and patterns) independently. Fully opaque clipping paths and semi-transparent masks are composited together to calculate the color and opacity of every pixel of the final image, using blending. Filter effects. Main article: Interactivity SVG images can interact with users in many ways. In addition to hyperlinks as mentioned below, any part of an SVG image can be made receptive to user interface such as changes in, mouse clicks, scrolling or zooming the image and other pointer, keyboard and document events. Event handlers may start, stop or alter animations as well as trigger scripts in response to such events. Linking SVG images can contain hyperlinks to other documents, using.

Through the use of the element or a, can link to SVG files that change the visible area of the document. This allows for creating specific view states that are used to zoom in/out of a specific area or to limit the view to a specific element. This is helpful when creating. Support in combination with the element also allow linking to and re-using internal and external elements. This allows coders to do more with less markup and makes for cleaner code. Scripting All aspects of an SVG document can be accessed and manipulated using scripts in a similar way to HTML. The default scripting language is (closely related to ) and there are defined (DOM) objects for every SVG element and attribute.

Scripts are enclosed in. Main article: SVG content can be animated using the built-in animation elements such as, and. Content can be animated by manipulating the DOM using ECMAScript and the scripting language's built-in timers. SVG animation has been designed to be compatible with current and future versions of (SMIL). Animations can be continuous, they can loop and repeat, and they can respond to user events, as mentioned above.

Fonts As with HTML and CSS, text in SVG may reference external font files, such as system fonts. If the required font files do not exist on the machine where the SVG file is rendered, the text may not appear as intended. To overcome this limitation, text can be displayed in an SVG font, where the required are defined in SVG as a font that is then referenced from the element. Metadata In accord with the 's initiative, SVG allows authors to provide about SVG content. The main facility is the element, where the document can be described using metadata properties (e.g. Title, creator/author, subject, description, etc.). Other metadata schemas may also be used.

In addition, SVG defines and elements where authors may also provide plain-text descriptive material within an SVG image to help indexing, searching and retrieval by a number of means. An SVG document can define components including shapes, gradients etc., and use them repeatedly. SVG images can also contain, such as and images, and further SVG images.

Example This code will produce the shapes shown in the image (excluding the grid). SVG exported from The use of SVG on the web was limited by the lack of support in older versions of (IE).

Many web sites that serve SVG images, such as, also provide the images in a raster format, either automatically by or by allowing the user directly to choose the file. Announced on 31 August 2010 that it had started to index SVG content on the web, whether it is in standalone files or embedded in, and that users would begin to see such content listed among their search results. It was announced on 8 December 2010 that would also begin indexing SVG files. The site announced an option to restrict image searches to SVG files on 11 February 2011. Native browser support was the first browser to support SVG in release version 3.2 in February 2004. As of 2011, all major desktop browsers, and many minor ones, have some level of SVG support. Other browsers' implementations are not yet complete; see for further details.

Some earlier versions of Firefox (e.g. Versions between 1.5 and 3.6 ), as well as a smattering of other now-outdated web browsers capable of displaying SVG graphics, needed them embedded in or to display them integrated as parts of an HTML webpage instead of using the standard way of integrating images with.

However, SVG images may be included in XHTML pages using., the inventor of the, has been critical of (earlier versions of) Internet Explorer for its failure to support SVG. (since 8.0) has support for the SVG 1.1 Tiny specification while Opera 9 includes SVG 1.1 Basic support and some of SVG 1.1 Full. Opera 9.5 has partial SVG Tiny 1.2 support.

It also supports SVGZ (compressed SVG). Browsers based on the (such as, and ) all have had incomplete support for the SVG 1.1 Full specification since 2005. The Mozilla site has an overview of the modules which are supported in Firefox and of the modules which are in progress in the development.

Gecko 1.9, included in, adds support for more of the SVG specification (including filters)., which uses the layout engine (a fork of the Gecko engine), supports SVG. Browsers based on (such as 's, and 's ) have had incomplete support for the SVG 1.1 Full specification since 2006. has partial SVG support. and older versions do not support SVG. IE9 (released 14 March 2011) supports the basic SVG feature set.

IE10 extended SVG support by adding SVG 1.1 filters. Microsoft Edge supports much of SVG 1.1. The also supports SVG. There are several advantages to native and full support: are not needed, SVG can be freely mixed with other content in a single document, and rendering and scripting become considerably more reliable. Plug-in browser support Internet Explorer, up to and including IE8, was the only major browser not to provide native SVG support.

IE8 and older require a plug-in to render SVG content. There are a number of plug-ins available to assist, including:. Open-Source JavaScript GUI Framework provides partial support for SVG 1.1, SMIL, DOM and style scripting in Internet Explorer (5.5 - 8.0) too. It is not dependent on any plugins and relies on presence of alternative Vector Graphics format VML in Internet Explorer., a widely deployed plugin.

from can support all web elements supported by WebKit, including SVG 1.0 and partially SVG 1.1. ( discontinued)., targets SVGT 1.2. Adobe SVG Viewer from plugin supports most of SVG 1.0/1.1. ( discontinued). ( discontinued). is another JavaScript library that takes advantage of the intersection between VML's and SVG's features to create vector graphics and animate them. for Internet Explorer from examotion GmbH, supports SVG 1.1 on and ( discontinued).

SVG Web is a JavaScript library for Web developers, targeted at Internet Explorer and dependent on the presence of an installed plugin on the client machine. SVG Web provides partial support for SVG 1.1, SVG Animation (SMIL), Fonts, Video and Audio, DOM and style scripting. On 5 January 2010, a senior manager of the Internet Explorer team at Microsoft announced on his official blog that Microsoft had just requested to join the of the W3C in order to 'take part in ensuring future versions of the SVG spec will meet the needs of developers and end users,' although no plans for SVG support in Internet Explorer were mentioned at that time. Internet Explorer 9 beta supported a basic SVG feature set based on the SVG 1.1 W3C recommendation. Functionality has been implemented for most of the SVG document structure, interactivity through scripting and styling inline and through CSS. The presentation elements, attributes and DOM interfaces that have been implemented include basic shapes, colors, filling, gradients, patterns, paths and text.

Mobile support SVG Tiny (SVGT) 1.1 and 1.2 are mobile profiles for SVG. SVGT 1.2 includes some features not found in SVG 1.1, including non-scaling strokes, which are supported by some SVG 1.1 implementations, such as Opera, Firefox and WebKit.

As shared code bases between desktop and mobile browsers increased, the use of SVG 1.1 over SVGT 1.2 also increased. Support for SVG may be limited to SVGT on older or more limited, or may be primarily limited by their respective operating system. Has optionally supported SVG Tiny since version 1.1.

At the SVG Open 2005 conference, demonstrated a mobile implementation of SVG Tiny 1.1 for the (CLDC) platform. Mobiles that use, as well as the 's built in browser, also include SVG support. However, even though it used the engine, the built-in browser did not support SVG prior to v3.0 (Honeycomb).

Prior to v3.0, Firefox Mobile 4.0b2 (beta) for Android was the first browser running under Android to support SVG by default. The level of SVG Tiny support available varies from mobile to mobile, depending on the SVG engine installed. Many newer mobile products support additional features beyond SVG Tiny 1.1, like gradient and opacity; this is sometimes referred as 'SVGT 1.1+', though there is no such standard. Has built-in support for SVG Tiny 1.1 since version 5.0. Support continues for WebKit-based BlackBerry Torch browser in OS 6 and 7.

's has built-in support for SVG. For example, icons are generally rendered using the platform's SVG engine. Nokia has also led the JSR 226: Scalable 2D Vector Graphics expert group that defines API for SVG presentation and manipulation.

This API has been implemented in S60 Platform 3rd Edition Feature Pack 1 and onward. Some also support SVG (such as ).

Most phones beginning with (by release date) support SVG Tiny 1.1. Phones beginning with also support such features as opacity and gradients. Phones with have support for JSR 226. Has supported SVG since version 7.5 SVG is also supported on various mobile devices from, and /.

ESVG, an SVG rendering library mainly written for devices, is available on some mobile platforms.
