ImageBitmapRenderingContext.transferFromImageBitmap() method displays the given ImageBitmap in the canvas associated with this rendering context. The ownership of the ImageBitmap is transferred to the canvas as well.

This method was previously named transferImageBitmap() , but was renamed in a spec change. The old name is being kept as an alias to avoid code breakage.

var gl = offscreen.getContext("webgl");
// ... some drawing using the gl context ...
// Transfer the current frame to the visible canvas
var bitmap = offscreen.transferToImageBitmap();
