import { Renderer } from '@antv/g-mobile-canvas';

const renderer = new Renderer();
// use existed context
const canvasElement = createMobileCanvasElement(context);

const canvas = new Canvas({
    canvas: canvasElement,
    renderer,
    //（可选）传入原本 DOM 环境下需要通过 window 获取的属性和方法，例如 dpr、rAF 等
    // @see https://g-next.antv.vision/zh/docs/api/canvas#devicepixelratio
    devicePixelRatio: 2,
    requestAnimationFrame,
    cancelAnimationFrame,
});
