The decodeURI() function decodes a Uniform Resource Identifier (URI) previously created by encodeURI() or a similar routine.

The svg element is a container that defines a new coordinate system and viewport. It is used as the outermost element of SVG documents, but it can also be used to embed an SVG fragment inside an SVG or HTML document.

The clipPathUnits attribute indicates which coordinate system to use for the contents of the <clipPath> element.

The amplitude attribute controls the amplitude of the gamma function of a component transfer element when its type attribute is gamma.

The <pattern> element defines a graphics object which can be redrawn at repeated x- and y-coordinate intervals ("tiled") to cover an area.

The <feFuncB> SVG filter primitive defines the transfer function for the blue component of the input graphic of its parent <feComponentTransfer> element.

The <font-face-format> SVG element describes the type of font referenced by its parent <font-face-uri>.

The <font> SVG element defines a font to be used for text layout.

The <font-face-name> element points to a locally installed copy of this font, identified by its name.

The <feTile> SVG filter primitive allows to fill a target rectangle with a repeated, tiled pattern of an input image. The effect is similar to the one of a <pattern>.
