HarmonyOS Image组件如何随时随地获取图片中心点的x，y坐标信息（在不借助PixMap或者martix4的情况下）

import matrix4 from '@ohos.matrix4';  
import componentUtils from '@ohos.arkui.componentUtils';  
@Entry  
@Component  
struct Utils {  
@State x: number = 120;  
@State y: number = 10;  
@State z: number = 100;  
@State value: string = '';  
private matrix1 = matrix4.identity().translate({ x: this.x, y: this.y, z: this.z });  
build() {  
  Column() {  
    Image($r("app.media.img"))  
      .transform(this.matrix1)  
      .translate({ x: 20, y: 20, z: 20 })  
      .scale({ x: 0.5, y: 0.5, z: 1 })  
      .rotate({  
        x: 1,  
        y: 1,  
        z: 1,  
        centerX: '50%',  
        centerY: '50%',  
        angle: 300  
      })  
      .width(300)  
      .height(100)  
      .key("image_01")  
    Button('getRectangleById')  
    .onClick(() => {  
      this.value = JSON.stringify(componentUtils.getRectangleById("image_01"))  
    }).margin(10).id('onClick')  
    Text(this.value)  
      .margin(20)  
      .width(300)  
      .height(300)  
      .borderWidth(2)  
  }.margin({left: 50})  
}  
}
