Remarks

Windows uses the default, preferred size as a guide to scale the thumbnail image without reducing the quality of the image. It does not guarantee the size of the thumbnail image that is retrieved.

Using thumbnail modes

Use this enumeration to determine the thumbnail image you get when you call one of the getThumbnailAsync methods. These methods return the thumbnail image as a storageItemThumbnail object.

For example, you can get a thumbnail image to preview a video file by calling storageFile.GetThumbnailAsync(ThumbnailMode) and specifying the videoView thumbnail mode.

To help you decide which mode you should use, see Guidelines and checklist for thumbnails.
