如何更改TextInput密码输入模式下passwordIcon的大小、颜色、位置

@Entry 
@Component 
struct TextInputExample { 
  @State text: string = '' 
  @State changeType: InputType = InputType.Password 
  @State isVisible: boolean = false 
  @State changeState: boolean = false 
  controller: TextInputController = new TextInputController() 
 
  build() { 
    Column() { 
      Flex({ direction: FlexDirection.Row }) { 
        Stack() { 
          TextInput({ text: this.text, controller: this.controller }) 
            .type(this.changeType) 
            .placeholderFont({ size: 16, weight: 400 }) 
            .showPasswordIcon(false) 
            .width(336) 
            .height(56) // 设置内间距让输入内容不超过图标位置 
            .padding({ 
              right: 50 
            }) 
            .onChange((value: string) => { 
              this.text = value 
            }) 
          // Image覆盖passwordIcon实现 
          Image($r(this.isVisible ? 'app.media.visible' : 'app.media.Invisible')) 
            .margin({ 
              left: 280 
              // left: 200 
            }) 
            .backgroundColor('#E7E8EA') 
            .width(20) 
            .height(20) 
            .onClick(() => { 
              this.changeState = !this.changeState 
              this.isVisible = !this.isVisible 
              if (this.changeState) { 
                this.changeType = InputType.Normal 
              } else { 
                this.changeType = InputType.Password 
              } 
            }) 
        } 
      } 
    }.width('100%').height('100%').backgroundColor('#F1F3F5') 
  } 
}
