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
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 } })
