Look in the DiagramLinks collection for the Diagram.

SX=0;SY=0;EX=0;EY=0; means the start and end points are offset zero logical units (pixels at 100%) from the center of the source and end objects.

Here's an example from a connector that I joined to the extremities of some relatively large elements.
24,75,SX=71;SY=214;EX=-273;EY=25;EDGE=2;$LLB=;LLT=;LMT=;LMB=;LRT=;LRB=;IRHS=;ILHS=;,Mode=3;EOID=13A6BC3D;SOID=3478A400;Color=-1;LWidth=0;,False, ,56,


If you want the absolute positions you need to get the center points from the objects at either end and calculate them.

Thanks for your reply,

I am saving the diagram as image using below method,
Diagram.SaveDiagramImageToFile(filepath);

Diagram in EA details:
Scale="100"
Cx="850" Cy="1098"

Image Details : Dimensions : 616 x 517

image dimensions and EA diagram dimensions not match.

How to save image with the same dimension as in EA??

I'm not sure the saved dimensions have any relation the internal location units.

Check the xmi export, or the feature to export the diagram image map from the cache.
