微信小程序 wx.canvasGetImageData

Question

用小程序 canvas 获取图像的信息报错.

      const ctx = wx.createCanvasContext('skinCanvas');
      // await this.editEye(ctx);
      ctx.drawImage("../imgs/body.png",0,0,450/2,450/2)
      ctx.draw(false,()=>{
        wx.canvasGetImageData({
          canvasId: 'skinCanvas',
          width: 1,
          height: 1,
          x: 0,
          y: 0,
          success(res) {
            console.log("res:",res)
          },
          fail(res) {
            console.log("faild",res)
          }
        })
      })

TypeError: window.atob is not a function

请问谁知道怎么弄呢? 有了解的大神吗?
