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().
ImageData()
Creates an ImageData object from a given Uint8ClampedArray and the size of the image it contains. If no array is given, it creates an image of a transparent black rectangle. Note that this is the most common way to create such an object in workers as createImageData() is not available there.
ImageData.data Read only
A Uint8ClampedArray representing a one-dimensional array containing the data in the RGBA order, with integer values between 0 and 255 (inclusive). The order goes by rows from the top-left pixel to the bottom-right.
ImageData.colorSpace Read only
A string indicating the color space of the image data.
ImageData.height Read only
An unsigned long representing the actual height, in pixels, of the ImageData.
ImageData.width Read only
An unsigned long representing the actual width, in pixels, of the ImageData.
