title: How to know the page starting points in the pdf page ? ,
body: <p>Problem :- I can parse the PDF position operators in content stream.
  If the cooridnates are started from the left bottom to my calculations are getting correct  and able to tag the content properly.</p>
  <p>q1) In case the starting coordinates are changed i.e(top left, or top right or bottom right).
  The parsed coordinates are not matching to tag content , in this case how exactly to calculation will happen.</p>
  <p>q2) If the starting points are changed how the content stream will represent it ?</p>

  <p>The Page coordinates(0,0) starts from top left.  similarly there might be scenarios the coordinates might start  from top right and bottom right , now the question is how to tag this kinds of files .</p>
