const ctx = canvas.getContext("2d")

// var image = new Image()

// image = new Image()

// image.src = this.data.background_res

// image.onload = function() {

// Promise.all([

// createImageBitmap(this, 10, 10, 100, 100),

// ]).then(function(sprites) {

// ctx.drawImage(sprites[0], 50, 50,sprites[0].width,sprites[0].height);

// });

// }

ctx.drawImage(this.data.background_res,0,0)

报如下错误。我要将本地的图片 座位 canvas的背景。
