Set the SimpleRuler Property to false. Setting it to True, draws the ruler without tick marks (which means that the ruler will simply be a line)

Guna,
In LEADTOOLS version 16 there is a method called GetAnnotationContainer Method which you can use to get the values in the annotation object.

However, such method does not exist in version 15, the only way for you would be to save the annotation objects that you have in your medical viewer, then load them into a RasterImageViewer object and use this object to get to the annotation container and then to the ruler object.

I do not have a sample code that does that. However, you check one of our Annotation demos that use our RasterViewer to load and save annotation. You can find a demo here:
