ImageKnife 这个控件可以监听加载完成后的图片再获取图片的实际宽高吗

let imageKnifeOption: RequestOption = new RequestOption(); 
imageKnifeOption.load(“https://img2.baidu.com/it/u=3803237529,2189230955&fm=253&fmt=auto&app=138&f=JPEG?w=800&h=500”) 
.addListener({callback:(err:BusinessError|string, data:ImageKnifeData) => { 
  if (data.isPixelMap()) { 
    console.log("TEST== data: " + JSON.stringify(data)) 
    if (data.drawPixelMap) { 
      let pixelmap = data.drawPixelMap.imagePixelMap; 
      if (pixelmap) { 
        console.log("TEST== pixelmap: " + JSON.stringify(pixelmap)) 
        this.pixelMap = pixelmap; 
 
        pixelmap.getImageInfo((error, imageInfo) => { 
          if(error) { 
            console.log(‘getImageInfo failed.’); 
          } else { 
            let size = imageInfo.size 
            console.log("TEST== size: " + JSON.stringify(size)) 
          } 
        }) 
 
      } 
    } 
  } 
  return false; 
}}) 
let imageKnife:ImageKnife|undefined = ImageKnifeGlobal.getInstance().getImageKnife(); 
if(imageKnife != undefined){ 
  imageKnife.call(imageKnifeOption) 
} 
}
