sealed class

A color matrix (also commonly called a "color twist matrix") is used to transform one color into another, by considering the color definition to be a 3D vector into a color cube. Only because we now have an alpha channel, it is actually a 4D vector into a color hypercube!

It is a 5x5 matrix and is used to transform an {R,G,B,A,1} color. Note that the color vector is considered to be "wide" rather than "tall" (compare this to the System.Drawing.Drawing2D.Matrix class and a Point , which is considered to be tall, rather than wide).

You can retrieve any Item from the matrix (this is the indexer property), or you can use one of the 25 properties prefixed with "Matrix" to get or set the values.

The matrix is applied with the ImageAttributes.SetColorMatrix() method.
