Physical position and size of the image in the viewer (single item mode).
public LeadRect ImageBounds { get; }
The physical position and size of the image in pixels (single item mode).
This is a helper property for applications that use ImageViewer in single item mode. It is a shortcut to GetItemViewBounds using ActiveItem. For more information, refer to Image Viewer in Single Item Mode.
