function getScaledImageAsThumbnailAsync(mode)
Public Function GetScaledImageAsThumbnailAsync (mode As ThumbnailMode) As IAsyncOperation(Of StorageItemThumbnail)
Parameters
- mode
- ThumbnailMode
The enum value that describes the purpose of the thumbnail and determines how the thumbnail image is adjusted.
For guidance about choosing the best thumbnail mode, see Guidelines and checklist for thumbnails.
Returns
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.

function getScaledImageAsThumbnailAsync(mode, requestedSize)
Public Function GetScaledImageAsThumbnailAsync (mode As ThumbnailMode, requestedSize As UInteger) As IAsyncOperation(Of StorageItemThumbnail)
Parameters
- mode
- ThumbnailMode
The enum value that describes the purpose of the thumbnail and determines how the thumbnail image is adjusted.
For guidance about choosing the best thumbnail mode, see Guidelines and checklist for thumbnails.
- requestedSize
-
UInt32
unsigned int
uint32_t
The requested size, in pixels, of the longest edge of the thumbnail. Windows uses the requestedSize as a guide and tries to scale the thumbnail image without reducing the quality of the image.
If Windows can't find a thumbnail image that it can scale to meet the requested size, a larger thumbnail might be returned. If no larger thumbnail is available, a thumbnail image that is smaller than the requested size might be returned.
Returns
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.
