How to draw the edge using the relative points and anchor information available in the .notation [message #1075312]

How to draw the edge using the relative points and anchor information available in the .notation file ?

if my source port is at the location (x1,y1) and target port is at the location (x2,y2), how to draw the edge between them using the relative bendpoint and anchor information ?

Basically , how to calculate the list of lines (required to draw the edge) to draw ?

For example:

 <bendpoints xmi:type="notation:RelativeBendpoints" xmi:id="_jlXcEndlEeK9gIAa9s5AVQ" points="[-4, 0, 774, -107]$[-817, 0, -39, -107]$[-817, 107, -39, 0]$[-798, 107, -20, 0]"/>
    <sourceAnchor xmi:type="notation:IdentityAnchor" xmi:id="_p7G2IHdlEeK9gIAa9s5AVQ" id="(0.2,0.4)"/>
    <targetAnchor xmi:type="notation:IdentityAnchor" xmi:id="_p7IEQHdlEeK9gIAa9s5AVQ" id="(1.0,0.5)"/>

can anybody explain it in a generalized manner ?
