ImageData()

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

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.

Syntax

new ImageData(array, width, height);
new ImageData(width, height);

Parameters

array
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.
width
An unsigned long representing the width of the represented image.
 height
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.

Example

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