问题描述

使用 Taro.canvasGetImageData 获取画布像素时会提示:

支付宝小程序暂不支持 canvasGetImageData

WechatIMG219

但是支付宝小程序 已经支持 获取画布像素的接口了
详情 https://docs.alipay.com/mini/api/ui-canvas getImageData 部分

const ctx = my.createCanvasContext('awesomeCanvas');

ctx.getImageData
  x: 0,
  y: 0,
  width: 100,
  height: 100,
  success(res) {
    console.log(res.width) // 100
    console.log(res.height) // 100
    console.log(res.data instanceof Uint8ClampedArray) // true
    console.log(res.data.length) // 100 * 100 * 4
  }
})
