HarmonyOS鸿蒙Next中如何像安卓一样的.9图，实现图片指定区域拉伸

当前Image对于.9图的使用是给Image组件设置resizable属性，达到图片局部拉伸的效果，文档可参考：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/ts-basic-components-image#resizable11。

以下是简单的使用例子：

[@Entry](/user/Entry)
[@Component](/user/Component)
export struct Image9SliceSample {
  [@State](/user/State) left: number = 30;
  [@State](/user/State) right: number = 2;
  [@State](/user/State) top: number = 2;
  [@State](/user/State) bottom: number = 2;
  [@State](/user/State) fit: ImageFit = ImageFit.Cover;
  [@State](/user/State) w: number = 100
  [@State](/user/State) h: number = 200

  [@Builder](/user/Builder)
  ImageBuilder() {
    Image($r('app.media.image1'))
      .resizable({
        slice: {
          top: `${this.top}px`,
          left: `${this.left}px`,
          bottom: `${this.bottom}px`,
          right: `${this.right}px`,
        }
      })
      .width(`${this.w}px`)
      .height(`${this.h}px`)
  }

  build() {
    Column({ space: 20 }) {
      Text("123")
        .background(this.ImageBuilder)
        .width(`${this.w}px`)
        .height(`${this.h}px`);

      Blank().height(80)
        .height(`${this.h}px`)

      Row() {
        Button("add top to " + this.top).fontSize(10)
          .onClick(() => {
            this.top += 1
          })

        Button("add bottom " + this.bottom).fontSize(10)
          .onClick(() => {
            this.bottom += 1
          })

        Button("add left " + this.left).fontSize(10)
          .onClick(() => {
            this.left += 1
          })

        Button("add right " + this.right).fontSize(10)
          .onClick(() => {
            this.right += 1
          })
      }

      Row() {
        Button("reduce top to " + this.top).fontSize(10)
          .onClick(() => {
            this.top -= 1
          })

        Button("reduce bottom " + this.bottom).fontSize(10)
          .onClick(() => {
            this.bottom -= 1
          })

        Button("reduce left " + this.left).fontSize(10)
          .onClick(() => {
            this.left -= 1
          })

        Button("reduce right " + this.right).fontSize(10)
          .onClick(() => {
            this.right -= 1
          })
      }

      Row() {
        Button("add w").fontSize(10)
          .onClick(() => {
            this.w += 10
          })

        Button("add h").fontSize(10)
          .onClick(() => {
            this.h += 10
          })
      }
    }
    .backgroundColor(Color.Orange)
    .width('100%').height('100%')
  }
}
