The ImageData interface represents the underlying pixel data of an area of a <canvas> element. It is created using the ImageData() constructor or creator methods on the CanvasRenderingContext2D object associated with a canvas: createImageData() and getImageData(). It can also be used to set a part of the canvas by using putImageData().

The CSS repeating-linear-gradient function creates an <image> consisting of repeating gradients. It works similarly to the basic linear gradients as described by linear-gradient(), and takes the same arguments. However, it automatically repeats the color stops infinitely in both directions. The color stops' positions shift by multiples of the length of a basic linear gradient (the difference between the last color stops' position and the first).
