Mozilla's getting a new look. What do you think?


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 ImageBitmapRenderingContext.transferImageBitmap() 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.


void ImageBitmapRenderingContext.transferImageBitmap(bitmap)


An ImageBitmap object to transfer.



<canvas id="htmlCanvas"></canvas>


var htmlCanvas = document.getElementById("htmlCanvas").getContext("bitmaprenderer");

// Draw a WebGL scene offscreen
var offscreen = new OffscreenCanvas(256, 256);
var gl = offscreen.getContext("webgl");

// ... some drawing using the gl context ...

// Transfer the current frame to the visible canvas
var bitmap = offscreen.transferToImageBitmap();


Currently drafted as a proposal: OffscreenCanvas.
