通过picker选择图片后，返回file://***协议，如何通过Image展示？

import picker from '@ohos.file.picker'; 
 
@Entry 
@Component 
struct Index { 
  @State imagePath: string = '' 
  ; 
 
  build() { 
    Column() { 
      Button('select') 
        .onClick(() => { 
          let PhotoSelectOptions = new picker.PhotoSelectOptions(); 
          PhotoSelectOptions.MIMEType = picker.PhotoViewMIMETypes.IMAGE_TYPE; 
          PhotoSelectOptions.maxSelectNumber = 5; 
          let photoPicker = new picker.PhotoViewPicker(); 
          photoPicker.select(PhotoSelectOptions).then((PhotoSelectResult) => { 
            this.imagePath = PhotoSelectResult.photoUris?.[0] ?? ''; 
          }) 
        }) 
      Image(this.imagePath) 
        .width(100) 
    } 
    .width('100%' 
    ) 
  } 
}
