这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

ImageBitmapRenderingContext interface is a canvas rendering context that provides the functionality to replace the canvas's contents with the given ImageBitmap . Its context id (the first argument to HTMLCanvasElement.getContext() or OffscreenCanvas.getContext() ) is "bitmaprenderer" .

This interface is available in both the window and the worker 上下文。

方法

ImageBitmapRenderingContext.transferFromImageBitmap()

显示给定 ImageBitmap in the canvas associated with this rendering context. Ownership of the ImageBitmap is transferred to the canvas. This was previously named transferImageBitmap() , but was renamed in a spec change. The old name is being kept as an alias to avoid code breakage.
