canvas使用lineTo()方法绘制的斜线段，会产生锯齿
使用这个方法并没有起到预想中的效果
context.imageSmoothingEnabled = true;
请问在canvas中，一般采取什么方法做到斜线抗锯齿？

let width = canvas.width,height=canvas.height;if (window.devicePixelRatio) {canvas.style.width = width + "px";canvas.style.height = height + "px";canvas.height = 高度 * window.devicePixelRatio;canvas.width = 宽度 * window.devicePixelRatio;ctx.scale(window.devicePixelRatio, window.devicePixelRatio);}
let width = canvas.width,height=canvas.height;
if (window.devicePixelRatio) {
canvas.style.width = width + "px";
canvas.style.height = height + "px";
canvas.height = 高度 * window.devicePixelRatio;
canvas.width = 宽度 * window.devicePixelRatio;
ctx.scale(window.devicePixelRatio, window.devicePixelRatio);
}
