How to set position of a PDEPath object

Hi,
I am a beginer in plug-in development in Acrobat SDK.
I was trying to reflow contents inside pdf. I was able to reflow most  of the content except PDEPath object.as

For PDEPath object re-flow I was using  function PDEElementSetMatrix (PDEElement pdeElement, ASFixedMatrixP matrixP);

and the path object was not getting positioned at given place. Rather it was getting placed outside page margin very far above the page.

Another issue is that when ever I was trying to get position co-ordinates of any PDEPath object, using PDEElementGetMatrix function.
It was coming 0,0 as co-ordinate.

Can anyone help me to know what could be the problem here.

Thanks
