Use this tag for questions related to the OffcreenCanvas web API.
Just like the HTMLCanvasElement, the OffscreenCanvas API offers a way to draw graphics, make photo compositions, create animations, and do real-time video processing or rendering.
This API differs from the HTMLCanvasElement in that it is not hooked by a DOM node, and can thus live in a Web Worker. This offers the advantage of both producing complex graphics without blocking the main UI thread, and to be able to run animation smoothly even when the main thread is blocked.
