LightBox不在8号角显示图像

Question

在我的申请中，我添加：

"@ngx-gallery/core": "^4.0.3",
"@ngx-gallery/gallerize": "^4.0.3",
"@ngx-gallery/lightbox": "^4.0.3",

我从API读取了图像列表，并将其作为ImageItem列表放在this.items中，但是在页面灯箱中不起作用！这是我在ts中的方法：

GetGallery() {
  this.onlineSaleService.GetGalleryImages().subscribe((data: any[]) => {
    debugger;

    this.items = data['Result'].map(item => new ImageItem({ src:this.root+item.ImageName, thumb: this.root+item.ImageName,textProperty:item.Title }));
    this.galleryItem=data['Result'];
    const lightboxRef = this.gallery.ref('lightbox');
    lightboxRef.setConfig({
      imageSize: ImageSize.Cover,
      thumbPosition: ThumbnailsPosition.Top
    });

    lightboxRef.load(this.items);
  });
}

这是我的html代码：

<a  (click)="lightbox.open(0)"> gallery</a>

这是调试器中的结果：

这是结果：

这是package.json代码：

最终我阅读了文档并找到了解决方法：

    lightboxRef.setConfig({
  loadingMode: 'indeterminate', 
});

确定将显示图像加载进度（它使用HttpClient下载图像）。不确定将使用本机加载程序。enter link description here
