ImageData

Constructors

ImageData()

Creates an ImageData object from a given Uint8ClampedArray or Float16Array 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.
