The ImageBitmap.close() method disposes of all graphical resources associated with an ImageBitmap.
void ImageBitmap.close()
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
