function clipImage(path){
const canvas = document.createElement('canvas')
canvas.width = 200

const ctx = canvas.getContext('2d')
const img = document.createElement('img')
img.src = path
img.setAttribute("crossOrigin",'Anonymous')
img.onload = function (){
ctx.drawImage(this,0,0,200,100)
console.log(canvas.toDataURL())

使用 ctx.arc()和 ctx.clip()进行裁剪 ctx.arc(x, y, radius, startAngle, endAngle); ctx.clip(); ctx.drawImage(img, x, y, width, height)
