This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use 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 spec changes.
The ImageBitmap.close() method disposes of all graphical resources associated with an ImageBitmap.
Syntax
void ImageBitmap.close()
Examples
var offscreen = new OffscreenCanvas(256, 256);
var gl = offscreen.getContext("webgl");
// ... some drawing using the gl context ...
var bitmap = offscreen.transferToImageBitmap();
// ImageBitmap { width: 256, height: 256 }
bitmap.close();
// ImageBitmap { width: 0, height: 0 } -- disposed
Specifications
Currently drafted as a proposal in the OffscreenCanvas specification.
