createImageData
Creates an opaque object whose data property contains a one-dimensional array of pixel values, initialized to transparent black.
Declaration
ImageData createImageData(
ImageData? imagedata
);Parameters
- sw:
The width of the pixel array.
- sh:
The height of the pixel array.
Return Value
An imageData object.
Discussion
This method is typically used to create additional pixel arrays that can be blitted to the canvas in a single operation. You can optionally pass in another imageData object as a parameter, instead of a width and height, to create a new imageData object with the same pixel dimensions as the specified object.
