Remarks

ImageSize is updated automatically by the item when a new value is set to Url, Image or SvgDocument. It can also be set to a custom value to create an item with a specific size for owner drawing or to be rendered at a later time using the virtualizer. For more information, refer to Image Viewer Items.

ImageSize property of ImageViewer will update this member if this is the active item when the viewer is used in single item mode.
