* Understand Compositing and Color extensions in SVG 1. 2 in 30 minutes!

The example above shows a notation named " type-image-svg " that references the standard public FPI and the system identifier ( the standard URI ) of an SVG 1. 1 document, instead of specifying just a system identifier as in the first example ( which was a relative URI interpreted locally as a MIME type ).

Since 2001, the SVG specification has been updated to version 1. 1 ( current Recommendation ) and 1. 2 ( still a Working Draft ).

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.

SVG Tiny later became an autonomous Recommendation ( current version 1. 2 ) and the basis for SVG 1. 2.

In addition to these variants and profiles, the SVG Print specification ( still a Working Draft ) contains guidelines for printable SVG 1. 2 and SVG Tiny 1. 2 documents.

Conforming SVG 1. 1 viewers will display compressed images.

Examples include Web accessibility a set of guidelines and two accessible web portals designed for people developing reading skills are peepo. com — try typing a letter with your keyboard for more — and peepo. co. uk with enhanced graphics, unique style controls and improved interactivity ( requires an SVG supported browser ).

* Export diagrams as GIF, PNG, PS, EPS, PGML and SVG.

Modern imaging systems like PostScript, Asymptote, Metafont, and SVG use Bézier splines composed of cubic Bézier curves for drawing curved shapes.

It is also possible to add support for new shapes by writing simple XML files, using a subset of Scalable Vector Graphics ( SVG ) to draw the shape.

Other approaches, such as individual frames served by AJAX, or SVG images may be animated via JavaScript or SMIL.

Scalable Vector Graphics ( SVG ) is a family of specifications of an XML-based file format for two-dimensional vector graphics, both static and dynamic ( i. e., interactive or animated ).

The SVG specification is an open standard that has been under development by the World Wide Web Consortium ( W3C ) since 1999.

SVG images and their behaviors are defined in XML text files.

As XML files, SVG images can be created and edited with any text editor, but it is often more convenient to create them with drawing programs such as Inkscape.

All major modern web browsers — including Mozilla Firefox, Internet Explorer 9, Google Chrome, Opera, and Safari — have at least some degree of support for SVG and can render the markup directly.

Earlier versions of Microsoft Internet Explorer ( IE ) do not support SVG natively.

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.

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.

SVG Tiny 1. 2 was initially released as a profile and later refactored to be a complete specification, including all needed parts of SVG 1. 1 and SVG 1. 2.

The SVG 1. 1 specification defines 14 functional areas or feature sets:

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 Great Seal of the United States ).

: Since 2008, there has been discussion among professional users of SVG that either gradient meshes or preferably diffusion curves could usefully be added to the SVG specification.

* Opera ( 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.

* Browsers based on the Gecko layout engine ( such as Firefox, Flock, Camino, and SeaMonkey ) all have had incomplete support for the SVG 1. 1 Full specification since 2005.

Gecko 1. 9, included in Firefox 3. 0, adds support for more of the SVG specification ( including filters ).

* Browsers based on WebKit ( such as Apple's Safari, Google Chrome, and The Omni Group's OmniWeb ) have had incomplete support for the SVG 1. 1 Full specification since 2006.

* Scalable Vector Graphics ( SVG ) ( a specification for two-dimensional vector graphics developed by the World Wide Web Consortium ( W3C ).

Hypermedia applications may be developed on embedded devices for the mobile and the Digital signage industries using the Scalable Vector Graphics ( SVG ) specification from W3C ( World Wide Web Consortium ).

The SVG file specification uses this type of blending, and this is one of the models that can be used in PDF.

The K700 also has a built-in email client, WAP and HTML browser which supports the SVG Tiny specification, a media player which is capable of playing MIDI, WAV, MP3 and AAC audio files and 3GP, MPEG-4 video files, and an FM radio ( which is only operable when the supplied headphones are inserted ).

This is commonly referred to as a " path " in vector graphics standards ( like SVG ) and vector graphics programs ( like Adobe Illustrator and Inkscape ).

The difference with the GIF image, is that the SVG image will be parsed within the SGML document, according to the declarations in the DTD, where the GIF image is just referenced as an opaque external object ( which is not parsable with SGML ) via its " data " attribute ( whose value type is an opaque ENTITY ).

Although not directly comparable to SVG since it is a bitmap-based format, the Canvas element in HTML5 provides an approach to rendering dynamic graphics in HTML that is procedural rather than declarative: instead of specifying the shapes to draw in XML, the author executes drawing commands from a script.

Conversely SVG is an ideal PDL for print-oriented uses, as it contains all the functionality required to place each glyph and image in a chosen location on the final page.

A much more print-specialized subset of SVG ( SVG Print, authored by Canon, HP, Adobe and Corel ) is a W3C Working Draft.

When an SVG image has been compressed with the industry standard gzip algorithm, it is referred to as an " SVGZ " image and uses the corresponding filename extension.

Apart from this, there is very little difference between SVG 1. 1 and SVG 1. 0.

The MPEG-4 Part 20 standard-Lightweight Application Scene Representation ( LASeR ) and Simple Aggregation Format ( SAF ) is based on SVG Tiny.

: Unicode character text included in an SVG file is expressed as XML character data.

The default scripting language is ECMAScript ( closely related to JavaScript ) and there are defined Document Object Model ( DOM ) objects for every SVG element and attribute.

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 glyphs are defined in SVG as a font that is then referenced from the element.

Google 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 HTML, and that users would begin to see such content listed among their search results.
