HarmonyOS PixelMap等通过NAPI提供的复杂类型，由于有部分实现在Native侧，在组件间如何传递？

let icon: Resource = $r('app.media.app_icon')  
let context = getContext()  
let iconDescriptor = context.resourceManager.getDrawableDescriptor(icon);  
let iconPixel = iconDescriptor.getPixelMap()  
  
@Entry  
@Component  
struct pixelTest {  
  @State icon: PixelMap = iconPixel;  
  
  build() {  
    Column() {  
      Image(this.icon)  
        .width(100).height(100)  
      subComponent({  
        icon: this.icon,  
        icon2: this.icon  
      })  
    }.width('100%').height('100%')  
  }  
}  
  
@Component  
struct subComponent {  
  @Link icon: PixelMap;  
  icon2: PixelMap | ResourceStr = '';  
  
  build() {  
    Column() {  
      Image(this.icon)  
        .width(100).height(100)  
      Image(this.icon2)  
        .width(100).height(100)  
    }  
  }  
}
