web.canvas.ImageData
The ImageData interface represents the underlying pixel data
an area of a <canvas> element. It is created using the ImageData()
or creator methods on the web.canvas.CanvasRenderingContext2D
associated with a canvas: createImageData() and getImageData().
can also be used to set a part of the canvas by using putImageData().
The ImageData interface represents the underlying pixel data an area of a `<canvas>` element. It is created using the `ImageData()` or creator methods on the `web.canvas.CanvasRenderingContext2D` associated with a canvas: `createImageData()` and `getImageData()`. can also be used to set a part of the canvas by using `putImageData()`.
constructorcljs
(constructor & args)Constructor.
The ImageData() constructor returns a newly instantiated web.canvas.ImageData object built from the typed array given and having the specified width and height.
array Optional
A js.Uint8ClampedArray containing the underlying pixel representation of the image. If no such array is given, an image with a black rectangle of the specified width and height will be created.
width
An unsigned long representing the width of the image.
height
An unsigned long representing the height of the image. This value is optional if an array is given: the height will be inferred from the array's size and the given width.
