title: change or move text position in a PDF file
body: <p>Via a .net application, I want to modify a pdf document by moving the first line or the first word little space down.</p>
  
  <p>is there any library that can help me to change some text position on the pdf document programmatically?</p>
  
  <p>i want to change the y position of a text object on the pdf, this operation will be done for many files, and i don't want to use any intermediate process like converting to svg or word, i want a direct modification to the pdf file.</p>
  
  <p>i have checked some libraries like PdfSharp , iTextSharp , PDFLibNet , Amyuni, pdfclown and i didn't find a solution for this problem.</p>
