ThumbnailMode ThumbnailMode ThumbnailMode ThumbnailMode Enum

Describes the purpose of the thumbnail to determine how to adjust the thumbnail image to retrieve.

Syntax

Declaration

public enum ThumbnailModepublic enum ThumbnailModePublic Enum ThumbnailModepublic enum ThumbnailMode

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(ThumbnailMode) 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 GetThumbnailAsync(ThumbnailMode) and specifying the videoView thumbnail mode.

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