TryDisplayStorageFileBitmapAtCursorAsync(StorageFile)	Attempts to asynchronously display a bitmap from a storage file at the current cursor position.
TryDisplayStorageFileBitmapAtPointAsync(StorageFile, Point, Int32)	Attempts to asynchronously display a bitmap from a storage file at a particular point, scaled to a particular width.
TryDisplayStorageFileBitmapAtPointAsync(StorageFile, Point)	Attempts to asynchronously display a bitmap from a storage file at a particular point.
TryDisplayStoredBitmapAtCursorAsync(LineDisplayStoredBitmap)	Attempts to asynchronously display a stored bitmap from at LineDisplayStoredBitmap object at the current cursor position.
TryDisplayTextAsync(String, LineDisplayTextAttribute, Point)	Try to display the specified text at a specified position in the line display window, using the specified display attribute.
TryDisplayTextAsync(String, LineDisplayTextAttribute)	Try to display the specified text in the line display window, using the specified display attribute.
TryDisplayTextAsync(String)	Try to display the specified text in the line display window.
