  ThumbnailMode mode

For guidance about choosing the best thumbnail mode, see Guidelines and checklist for thumbnails.

Return value

Type: IAsyncOperation<StorageItemThumbnail>

When this method completes successfully, it returns a StorageItemThumbnail that represents the thumbnail image or null if there is no thumbnail image associated with the item.


In Windows 8, the GetThumbnailAsync method has just one immersive monitor at a time that can show the Windows Store app user interface. In Windows 8.1, the Windows Store app user interface can appear on multiple monitors, with the option to show a single app on multiple monitors simultaneously. For scaling, consider multiple scale factors at once.

In Windows 8.1, the GetThumbnailAsync method can return any size thumbnail. Therefore, apps that display local pictures should call this method to get the scaled image they want to display. This ensures that apps benefit from all cache and performance optimizations, including a special mechanism to obtain thumbnails from the cloud without downloading the full file.

For guidance about choosing the best thumbnail mode, see Guidelines and checklist for thumbnails.
