The <feColorMatrix> SVG filter element changes colors based on a transformation matrix. Every pixel's color value [R,G,B,A] is matrix multiplied by a 5 by 5 color matrix to create new color [R',G',B',A'].

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

Now that we covered the basics of the SVG internals, we will take a look at some tools to work with SVG files.

There are several basic shapes used for most SVG drawing. The purpose of these shapes is fairly obvious from their names. Some of the parameters that determine their position and size are given, but an element reference would probably contain more accurate and complete descriptions along with other properties that won't be covered in here. However, since they're used in most SVG documents, it's necessary to give them some sort of introduction.

The <feMergeNode> SVG takes the result of another filter to be processed by its parent <feMerge>.

The <feComponentTransfer> SVG filter primitive performs color-component-wise remapping of data for each pixel. It allows operations like brightness adjustment, contrast adjustment, color balance or thresholding.

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>.

The <feFlood> SVG filter primitive fills the filter subregion with the color and opacity defined by flood-color and flood-opacity.

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

The <polygon> SVG element defines a closed shape consisting of a set of connected straight line segments. The last point is connected to the first point.
