Scalable Vector Graphics (SVG) is an XML -based vector image format for defining two-dimensional graphics, having support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium since 1999. SVG images are defined in a vector graphics format and stored in XML text files.
Further information: Commons:Help:SVG. Scalable Vector Graphics is a commonly used file format for providing a geometrical description of an image using basic objects such as labels, circles, lines, curves and polygons. An image can be reduced or enlarged to an arbitrary size, and will not suffer image data loss, nor will it become pixelated.
In some cases, it may be desirable to add clickable annotations to an image. The templates Template:Annotated image and Template:Annotated image 4 exist for this purpose. These templates allow wikitext (e.g., regular text, wikilinks, allowed HTML code, references, and other templates) to be included on the image itself. They may also be used to ...
The procedure for adding images to articles is the same, regardless of whether the image was uploaded to Commons or directly to English Wikipedia. To make your uploaded file appear in an article, you need to insert it: edit the article and add the syntax [[File:Image name|thumb|Caption]] where you want the file to appear.
SVG-edit is a cross-browser web-based, JavaScript -driven web tool, and has also been made into browser addons, such as an addon for Firefox, a Chrome extension, and a standalone widget for Opera. [1] There's also an experimental SVG editing extension on MediaWiki that uses SVG-edit. [2]
For guidance on the syntax for doing this, see Help:Infobox picture. In very brief summary, one hurdle that trips up many people when attempting to add an image to an infobox template is that most internally provide the wiki code that "wraps" the image. Accordingly, you do not usually add the brackets, number of pixels, and other code details ...
MediaWiki converts the SVG image to a PNG image. The SVG format is the working format of the stored image so that people can more easily convert images for use in different languages. If you're using a browser other than Internet Explorer, just keep clicking the image and you'll eventually get the full-size image, which will be the SVG version.
There are 4 basic choices for image file formats: SVG for simple diagrams (especially those that need to be scaled). JPEG for photographic images. GIF for animated images. PNG for everything else. While some formats offer multiple compression systems, in general the format and the compression system are tied together.
