public IAsyncOperation<StorageItemThumbnail> GetScaledImageAsThumbnailAsync(ThumbnailMode mode);
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

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.

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

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.

Parameters

mode
ThumbnailMode

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.

options
ThumbnailOptions

The enum value that describes the desired behavior to use to retrieve the thumbnail image. The specified behavior might affect the size and/or quality of the image and how quickly the thumbnail image is retrieved.

Returns

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.
