Public Class Ruler
The ruler tracks mouse movements and modifications being performed on an item, and displays markers over the scales indicating the current position in diagram's coordinate system. The colors of these markers can be changed using the PointerColor and ProjectionColor properties.
If EnableGuides is set to true, the ruler allows aligning several items by clicking on a scale and dragging. That displays alignment guides which follow the mouse pointer and move all selected items on their way. If no diagram elements are selected, all items are moved.
