HarmonyOS 矩阵变换问题demo

参考demo：

import matrix4 from '@ohos.matrix4';

@Entry
@Component
struct Index {
  @State x:number= 100;
  @State y:number= 100;
  @State perspective:number= 1;
  @State show:boolean= true;
  private matrix1 = matrix4.identity()

    .setPolyToPoly({ src: [{ x: 0, y: 0 }, { x: 200, y: 0 },  { x: 200, y: 200 },{ x: 0, y: 200 }],srcIndex:0,
      dst: [{ x: 50, y: 0 }, { x: 150, y: 0 }, { x: 200, y: 200 },{ x: 0, y: 200 }],dstIndex:0, pointCount: 4 })

  build() {
    Column(){

      Column(){
        Image($r("app.media.startIcon"))
          .width('200px')
          .height('200px')
        // if (this.show) {
        Image($r("app.media.startIcon"))
          // .scale({ centerY: '50%', centerX: '50%', x: 1, y: 1 })
          .transform(this.matrix1)
          .width('200px')
          .height('200px')
        // }

      }.width('80%').height('80%')

    }.width("100%").height("100%").onClick(()=>{
      console.log("tag "+ JSON.stringify(this.matrix1))
    })
  }
}
