HarmonyOS 启动页背景图适配

设置startIcon和自己页面的一个splash控件为同一张背景图后，会闪烁，startIcon展示的图片偏小，有没有启动页适配方案相关文档

@Component
export struct BrandSplash {
  build() {
    buildSplash()
  }
}

@Builder
export function buildSplash() {
  Image($r('app.media.splash_bg'))
    .width('100%')
    .height('100%')
    .objectFit(ImageFit.Contain)
    .backgroundColor($r('app.color.Wh0_u'))
}

module.json5配置
