The ImageData() constructor returns a newly instantiated ImageData object build from the typed array given and having the specified width and height.

This constructor is the preferred way of creating such an object in a worker.


var imageData = new ImageData(array, width, height);
var imageData = new ImageData(width, height);


array Optional
A Uint8ClampedArray containing the underlying pixel representation of the image. If no such array is given, an image with a black rectangle of the given dimension will be created.
An unsigned long representing the width of the represented image.
An unsigned long representing the height of the represented image. This value is optional if an array is given: it will be inferred from its size and the given width.


var imageData = new ImageData(100, 100); // Creates a 100x100 black rectangle
// ImageData { width: 100, height: 100, data: Uint8ClampedArray[40000] }
