Remarks

You can access the LowLagPhotoControl for the capture device through MediaCapture.VideoDeviceController.

Thumbnails are supported for a low shutter lag single photos and photo sequences.

To enable thumbnails, set ThumbnailEnabled to true.

You can set the desired thumbnail size through DesiredThumbnailSize and set the thumbnail format through ThumbnailFormat.

Properties

DesiredThumbnailSize DesiredThumbnailSize DesiredThumbnailSize DesiredThumbnailSize

Gets or sets the desired size for thumbnails, which is the largest length of the image, either width or height.

public : unsigned int DesiredThumbnailSize { get; set; }
public uint DesiredThumbnailSize { get; set; }
Public ReadWrite Property DesiredThumbnailSize As uint
var uint = lowLagPhotoControl.desiredThumbnailSize;
lowLagPhotoControl.desiredThumbnailSize = uint;
Value
unsigned int uint uint uint

The desired thumbnail size.

Remarks

The actual dimension of the thumbnail is not guaranteed to be the value specified by DesiredThumbnailSize, but the system will attempt to create thumbnails as close as possible to this value.
