- 当前 Bug 的表现（可附上截图）

小程序wx.chooseImage拍照，drawImage绘图 微信闪退

- 预期表现

可以正常绘图到页面

- 复现路径

- 提供一个最简复现 Demo

chooseImage: function (successfunc) {

let that = this;

// 'original',

wx.chooseImage({

count: 1,

sizeType: ['original'],

sourceType: ['camera'],

success(res) {

!!successfunc && successfunc(res)

}

})

},

that.canvas = wx.createCanvasContext('image-canvas', that)

that.canvas.drawImage(tempImagePath, 0, 0, width, canvasHeight)

that.canvas.draw()
